characterized by intense heat during the summer, and extreme cold in the winter. In New York, for example, the mean summer temperature ranges as high as 70.9 degrees, while the mean winter temperature is as low as 30.1 degrees; yet the mean temperature of the whole year is 53.2 degrees, affording no indication of these extremes. The mean annual temperature alone, therefore, would be entirely misleading, as it would give no idea of these alternations of heat and cold. Such being the case, the actual character of any climate will be far better realized by placing in juxtaposition the mean annual temperature, the mean temperature of the hot, and the mean temperature of the cooler months. First of all, then, I purpose showing the mean annual temperature, and also the mean temperatures for the hot and cooler months, of the four largest Australian centres. TABLE showing the Mean Annual Temperature, and also the Mean Temperatures for the Hot and Cooler Months, of Sydney, Melbourne, Adelaide, and Brisbane. Capital. Mean Annual Mean Temperature Mean Temperature Temeperature for the Hot Months for the Cold Months Sydney 62.9 70 58.7 Melbourne 57.5 64.9 53.8 Adelaide 63.1 72.4 58.4 Brisbane 67.74 75.2 64.3 Much will be gained by a comparison of these temperatures of the Australian capitals with those of some other cities in different parts of the world. A contrast of this kind will, in my opinion, help to a truer understanding of the climate of these capitals, than any other. Accordingly I made a successful application to Mr. H.C. Russell, for the corresponding temperatures of the following cities: London, Edinburgh, Dublin; Marseilles, Naples, Messina; New York, San Francisco, New Orleans; Bombay, Calcutta, and Madras.

It will be seen, however, on reference to the preceding tables, that the Australian climate is more equable than that of Southern Europe, for there is not such a marked difference between the hot and the cooler months. In the New England States of North America, as exemplified by New York, there are intensely hot summers and extremely cold winters--to which fact attention has already been drawn. And lastly, in India, the thermometer stands at such a height, winter as well as summer, that we can only be thankful our lines are cast in more pleasant places. Having thus compared the summer and winter temperatures of the Australian capitals with those of other cities in different parts of the world, it will be advisable to direct our attention to some details connected with the climate of these capitals, and of the corresponding colonies generally. Commencing with Sydney we find that the climate is characterized by the absence of very violent changes of temperature, owing in great measure to its proximity to the ocean, which in winter is about 10 degrees warmer than the air. Its summer climate is marked by the absence of hot winds, which do not come more than three or four times, and the are short-lived, seldom lasting more than five or six hours. For a short time in the midsummer of each year, Sydney is visited regularly by moist sea breezes, which are enervating to many persons. While these continue the temperature seldom rises to 80 degrees, but there is so much moisture that they are very oppressive. Otherwise the climate is one of the most enjoyable in the world. In other parts of New South Wales towns may be found varying in mean temperature from 45.8 degrees at Kiandra to 69.1 degrees at Bourke. Speaking generally it is a fact that for the same mean annual temperature in New South Wales the range between summer and winter temperature is less than it is in Europe. The climate of Melbourne is characterized by a low average humidity, moderate rainfall, and moderate winds, strong gales being of her rare occurrence. The most marked feature is the summer hot wind. A hot wind is always a northerly wind, and the highest temperature generally occurs a little before the win changes to west or south-west. When this takes place a sudden drop to a comparatively low temperature sometimes follows within a few minutes. These hot winds, however, are not frequent, only averaging eight or nine per annum. These characteristics will apply to all Victoria except the mountain ranges, where all the climatic elements vary with the altitude. The climate of Adelaide is certainly healthy, and, with the exception of the extreme heat occasionally experienced in summer, the weather may be described as enjoyable. It must be remembered, however, that these high temperatures are always accompanied by extreme dryness, the wet bulb thermometer usually reading at such times from 30 to 35 degrees, or even more, below the temperature of the air. The heat is, therefore, more bearable than if it was combined with the humid atmosphere. When the thermometer stands perhaps at something over 100 degrees, the wet bulb thermometer will show 65 degrees, and it is this which enables persons to bear the heat of the summer and carry on their usual pursuits with less inconvenience and discomfort than is felt in tropical and damp climates, though the temperature may be 15 or 20 degrees lower, but nearly saturated with aqueous vapour, as at Port Darwin, where during the rainy season of the north-west monsoon the thermometer may stand at only 88 degrees, whilst the wet bulb at the same time indicates 86 degrees. Such an atmosphere, it need hardly be said, is far more enervating than the hot and dry air of the Adelaide plains. The summer, which may be termed warm and dry, usually extends over, say, five months; and during the remainder of the year the climate is simply perfect. The temperature in mid-winter over the Adelaide plains rarely, if ever, reaches the freezing point, although there may be sharp frosts, and on still clear nights, so frequently experienced, copious dews. On the ranges, and on the high lying plains 150 miles north of Adelaide, lower temperatures are reached, indeed in some years there have been falls of snow. The climatic features of Brisbane are, as a mean expression, decidedly semi-tropical. The months from October to March may be classed as tropic when vegetation makes luxuriant growth, especially if the rainfall prove abundant. The rest of the year, from April to September, is marked by a dry, bracing, "continental" climate, during which the westerly wind often proves very cold, bleaching, and searching accompanied by great dryness accumulated during the passage of this current from southern-central Australia. Many settlers affirm that they feel the peculiar searching character of the dry cold "westerlies" more keenly than the more "honest" frost of the old country. Yet vigorous constitutions thoroughly enjoy the bracing nature of the westerly weather of winter. Hard ground frosts not unfrequently occur in the Darling Downs and Maranoa districts, especially during May, June, and July, in connection with the westerly type of climate; and, moreover, ice has at times been observed in the water-jugs of bedrooms, &c. As before intimated, the westerly winds are marked by great dryness, so that (saturation= 100) a percentage of relative humidity below 33 per cent. may occur during the prevalence of such phenomena, not only in Brisbane, but especially in the more western districts above mentioned. Such conditions are characterized by great diathermancy of atmosphere, and hence are frequently followed by days of considerable heat. Even in the tropics, in inland districts, ground frosts are known to have occurred owing to this extreme diathermancy of the atmosphere far from the coast, and the consequent attendant factor of active terrestrial radiation. In coast districts, or that fringe of country bordering the ocean north from Rockhampton, frost is of very rare occurrence, and the prevailing winds are between south-east and east-north-east, with a rainfall far more abundant than that obtaining in other parts of Queensland. The climate of the country surrounding the southern end of the Gulf of Carpentaria is very hot and trying from November to March, but genial thenceforward. It is certainly not unhealthy, and the fevers suffered from in the northern and gulf districts of Queensland are largely brought on by reckless or needless exposure. In addition to the foregoing, which has been obtained from head-quarters, certain questions were submitted by me as to the climatology of the different colonies. As it will be seen, these interrogations are somewhat extensive in their scope, and supply knowledge upon points, which is not ordinarily met with in my descriptions of Australian climate. In drafting them everything which had a bearing on health was included as far as possible, and consequently in a work of this kind they unquestionably deserve a prominent place. In arranging them I purpose placing the different replies after each question in the following order, namely, New South Wales, Victoria, South Australia, and Queensland. And in the different answers it should be borne in mind that Mr. H.C. Russell is responsible for New South Wales; Mr. R.L.J. Ellery for Victoria; Sir Charles Todd for South Australia; and Mr. Clement L. Wragge for Queensland. IS IT NOT A FACT THAT THE TEMPERATURE AND BAROMETRIC PRESSURE ARE EXPOSED TO SUDDEN AND MARKED CHANGES? HAVE YOU KNOWN THE TEMPERATURE TO FALL, SAY, AS MUCH AS 22 DEGREES IN 15 MINUTES? New South Wales.--The temperature sometimes changes rapidly in the summer, coming with a change from a hot wind to a cold southerly, although the instances are rare. Once in 30 years I have known such a change to amount to 20 degrees in 15 minutes. Under ordinary circumstances the change in temperature from hot to cold wind takes several hours to amount to 20 degrees. The fluctuations of barometric pressure are moderate, seldom amounting to half an inch in a day, or an inch in a week. In England, on the other hand, the pressure sometimes varies quickly to the extent of two inches. Victoria.--Yes; the temperature much more so than the barometric pressure; it has fallen from a high temperature to 20 and even 30 degrees sometimes in as many minutes, when a hot north wind has suddenly changed to a cold southerly one. But such sudden and great changes occur very seldom, and then only in the hot summer months, and are known as "the change." On several occasions in the last 30 years it has fallen from 105 degrees in the shade to 70 degrees and 65 degrees in the shade in less than an hour. South Australia.--Yes, in the summer; but, especially as regards temperature, rarely in the winter. One notable example occurred on February 9th, 1887, when during a heavy thunder-storm the temperature fell 25 degrees in 10 or 15 minutes, followed by a rising temperature. In other instances the fall of temperature has been almost equally rapid. From this it will be seen that we are subject to large and quick falls of temperature following extreme heat. The approach of hot weather is usually gradual, and the fall abrupt. The barometer has been known to show a rise of 6/10 of an inch in 24 hours; this, however, is exceptional. Queensland.--There is no record of a fall of as much as 22 degrees in 15 minutes. But, on the other hand, a rise of 30 degrees in three hours is a common feature over the Darling Downs after sunrise. Owing to the diathermancy of the atmosphere already referred to, it is a fact, nevertheless, that in the "continental" or inland districts of Southern Queensland the temperature in winter is subject to sudden and marked changes. Barometric pressure, owing to the comparatively low latitude, is not exposed to sudden and marked changes, except during hurricane conditions, which usually affect the central coast-line in February and March. AS A COROLLARY TO THE PRECEDING, WOULD YOU SAY THAT THE CLIMATE IS MARKED BY GREAT VARIABILITY? New South Wales.--No; just the opposite. Indeed, as regards Sydney itself. there are few cities in which so much uniformity of temperature and slow changes, are to be found. The cause of any great change is the hot wind, and as that seldom comes more than three or four times in the year, great changes are infrequent. The mean diurnal range in Sydney is 11 1/2 degrees, and taking a series of years it is very unusual for the range on any day to reach 25 degrees. Victoria.--No; because these are exceptional phenomena. In the late Spring and during early summer the climate may be said to be occasionally subject to sharp and sudden changes, which give it the character of variability. But the deviations from mean temperature, except for short periods, are not remarkable. South Australia.--Yes, in summer; but not in winter. Queensland.--Certainly not; with the exception of the wide diurnal range of temperature in winter in the southern "continental" districts, as at Cambooya and Thargomindah. The changes are, according to my knowledge, far more sudden and marked in the southern colonies (as during a "shift" from N.E. by W., to S.W. for instance, at Melbourne, and especially at Adelaide) than in Queensland and its coastal districts. WITH REGARD TO SUSTAINED, PROLONGED, OR CONTINUED HIGH TEMPERATURES DURING THE SUMMER MONTHS, FOR HOW MANY DAYS HAVE YOU KNOWN THE TEMPERATURE REMAIN CONTINUOUSLY AT A HIGH LEVEL? THIS IS A VERY IMPORTANT QUESTION, AS IT CONCERNS INFANTILE MORTALITY IN NO SMALL DEGREE; I SHALL BE GRATEFUL FOR YOUR EXPERIENCE? New South Wales.--Much depends upon what temperature is deemed a "high level." If we assume that 90 degrees and upwards is a high level, then such periods are very rare in Sydney; in fact during the past 24 years there have only been three. In 1868 there were three consecutive hot days of which the mean temperature was 91.8 degrees; in 1870 a period of four days with a mean temperature of 91.3 degrees; and in 1874 a period of four days with a mean temperature of 90.2 degrees. Since then, although sometimes near it, the temperature has never been for three days over 90 degrees. Taking a lower level, we have one period of nine days in 1870, the longest on record, during which the mean temperature was 82.6 degrees. It must, however, be distinctly understood that what is here taken is not the mean temperature of each 24 hours, but the highest temperature reached during the day, and which would not as a rule last more than three or four hours, if so much. If the mean temperature of the day were taken these temperatures, as given, would have to be reduced at least 10 per cent. Victoria.--It is very unusual to have a hot period lasting more than three days; when it does happen it is generally in February or March. In the majority of cases high temperatures (over 90 degrees) do not last more than one or two days. The exceptions generally occur in February or March, and have sometimes extended to four or five days hot weather, with a temperature of over 80 degrees with a maximum of about 90 degrees, has on a few occasions during the last 30 years extended from five to ten days; and in 1890, a memorable instance, to 12 days (the only case for 37 years). South Australia.--The longest stretch of continuous heat noted was in January and February 1857. On January 28th, 29th, and 30th, the temperature exceeded 100 degrees, and during the whole of February it was over 90 degrees on 25 days, and above 100 degrees on 12 days, the mean being 107 degrees. In January 1858 there were 10 consecutive days over 90 degrees, of which eight consecutive days were over 100 degrees. In January 1860 there were in the beginning of the month seven consecutive days, above 100 degrees (maximum 107.5 degrees). In the middle of the same month, seven days were over 90 degrees, of which five exceeded 100 degrees, two days reaching 113.7 degrees. These are, however, exceptions to our usual experience. Although there are several other instances of great heat, yet the foregoing will suffice to show what we occasionally suffer without much harm being done. Queensland.--During the period February 17th to February 23rd, 1891, the shade temperature at Townsville ranged between 81 degrees and 62 degrees, but at Cairns a range between 82 degrees and 70 degrees is of frequent occurrence, within at least fortnightly periods. ANY INFORMATION WITH REGARD TO HUMIDITY OF THE ATMOSPHERE ALSO, WILL BE OF GREAT VALUE. ALL PHYSICIANS ARE OF OPINION THAT A HIGH TEMPERATURE, COMBINED WITH MOISTURE, IS VERY IRRITATING TO THE LUNGS OF THOSE AFFECTED WITH PULMONARY DISEASE. Before setting forth the different answers in response to this, it will be desirable to refer briefly to the term "humidity." The humidity of the atmosphere is defined as the degree of its approach to saturation. Air completely saturated is represented by 100, and that absolutely free of vapour by 0. As a matter of fact, however, the latter never occurs; even in the driest regions of Arabia a humidity of 10 per cent. is almost unknown. For its estimation the Wet and Dry Bulb thermometers are employed. These consist of two ordinary thermometers. One has its bulb exposed so as to register the temperature of the air. The bulb of the other is covered with muslin; this latter material being kept wet through its connection with a cotton wick dipping into a vessel of water. The water ascends from this vessel by capillary attraction, spreads over the muslin, and evaporates quickly or slowly, according to the dryness or moistness of the atmosphere. Thus when the air is driest the difference between the two thermometers will be greatest, and, on the contrary, when it is completely saturated with moisture the two readings will be almost identical. New South Wales.--A considerable part of the colony, forming the western plains, is subject to great heat, caused, no doubt, by the sun's great power on treeless plains, and the almost total absence of cooling winds; yet, although in summer the temperature here frequently rises over 100 degrees, and sometimes up to 120 degrees, owing to the cold at night and in winter the mean temperatures are not greater than those of corresponding latitudes in the northern hemisphere. This region of the colony is remarkably dry, and stock of all kinds thrive well and are very free from disease. At Bourke, the driest place in the colony, the humidity for a long series of years is--in the spring 51 degrees, in the summer 49 degrees, in the autumn 61 degrees, and in the winter 74 degrees. At Sydney the humidity in the Spring is 69 degrees, in the summer 70 degrees, in the autumn 79 degrees, and in the winter 79 degrees.
