COAGULATED BLOOD UNDER THE VAGINAL WALLS.
This is common after calving, but sometimes occurs before, as the result of
accidental injury. The mass may be recognized by its dark hue and the
doughy sensation to the touch. It may be cut into and the mass turned out
with the fingers, after which it should be washed frequently with an
antiseptic lotion (carbolic acid 1 dram in 1 quart of water).
CONSTRICTION OF A MEMBER BY THE NAVEL STRING.
In early fetal life the winding of the navel string around a limb may cause
the latter to be slowly cut off by absorption under the constricting cord.
So at calving the cord wound round a presenting member may retard progress
somewhat, and though the calf may still be born tardily by the unaided
efforts of the mother, it is liable to come still-born, because the
circulation in the cord is interrupted by compression before the offspring
can reach the open air and commence to breathe. If, therefore, it is
possible to anticipate and prevent this displacement and compression of the
navel string it should be done, but if this is no longer possible, then the
extraction of the calf should be effected as rapidly as possible, and if
breathing is not at once attempted it should be started by artificial
means.
WATER IN THE HEAD OF THE CALF (HYDROCEPHALUS).
This is an enormous distention of the cavity holding the brain, by reason
of the accumulation of liquid in the internal cavities (ventricles) of the
brain substance. The head back of the eyes rises into a great rounded ball
(Pl. XIX, figs. 4 and 5), which proves an insuperable obstacle to
parturition. The fore feet and nose being the parts presented, no progress
can be made, and even if the feet are pulled upon the nose can not by any
means be made to appear. The oiled hand introduced into the passages will
feel the nose presenting between the fore limbs, and on passing the hand
back over the face the hard rounded mass of the cranium is met with. A
sharp-pointed knife or a cannula and trocar should be introduced in the
palm of the hand and pushed into the center of the rounded mass so as to
evacuate the water. The hand is now used to press together the hitherto
distended but thin and fragile walls, and the calf may be delivered in the
natural way. If the enlarged head is turned backward it must still be
reached and punctured, after which it must be brought up into position and
the calf delivered.
If the hind feet present first, all may go well until the body and
shoulders have passed out, when further progress is suddenly arrested by
the great bulk of the head. If possible, the hand, armed with a knife or
trocar, must be passed along the side of the shoulder or neck so as to
reach and puncture the distended head. Failing in this, the body may be
skinned up from the belly and cut in two at the shoulder or neck, after
which the head can easily be reached and punctured. If in such case the
fore limbs have been left in the womb, they may now be brought up into the
passage, and when dragged upon the collapsed head will follow.
If the distention is not sufficient to have rendered the bony walls of the
cranium thin and fragile, so that they can be compressed with the hand
after puncture, a special method may be necessary. A long incision should
be made from behind forward in the median line of the cranium with an
embryotomy knife (Pl. XXI, fig. 1) or with a long embryotome (Pl. XX, fig.
3). By this means the bones on the one side are completely separated from
those on the other and may be made to overlap and perhaps to flatten down.
If this fails they may be cut from the head all around the base of the
rounded cranial swelling by means of a guarded chisel (Pl. XX, fig. 8) and
mallet, after which there will be no difficulty in causing them to
collapse.
DROPSY OF THE ABDOMEN OF THE CALF (ASCITES).
This is less frequent than hydrocephalus, but no less difficult to deal
with. With an anterior presentation the fore limbs and head may come away
easily enough, but no effort will advance the calf beyond the shoulders.
The first thought should be dropsy of the belly, and the oiled hand
introduced by the side of the chest will detect the soft and fluctuating
yet tense sac of the abdomen. If there is space to allow of the
introduction of an embryotomy knife, the abdomen may be freely cut with
this, when the fluid will escape into the womb and parturition may proceed
naturally. If this can not be effected, a long trocar and cannula may be
passed between the first two ribs and straight on beneath the spine until
it punctures the abdomen. (Pl. XVIII, fig. 2.) Then the trocar is to be
withdrawn and the liquid will flow through the cannula and will be hastened
by traction on the fore limbs. In the absence of the trocar and cannula,
two or three of the first ribs may be cut from the breastbone, so that the
hand may be introduced through the chest to puncture the diaphragm with an
embryotomy knife and allow an escape of the water. In some slighter cases a
tardy delivery may take place without puncture, the liquid bulging forward
into the chest as the abdomen is compressed in the pelvic passages. With a
posterior presentation the abdomen may be punctured more easily either in
the flank or with a trocar and cannula through the anus.
GENERAL DROPSY OF THE CALF.
This occurs from watery blood or disease of some internal organ, like the
liver or kidney, and is recognized by the general puffed-up and rounded
condition of the body, which pits everywhere on pressure but without
crackling. If not too extreme a case, the calf may be extracted after it
has been very generally punctured over the body, but usually the only
resort is to extract it in pieces. (See "Embryotomy," p. 202.)
SWELLING OF THE CALF WITH GAS.
This is usually the result of the death and decomposition of the fetus when
extraction has been delayed for a day or more after the escape of the
waters. It is impossible to extract it whole, owing to its large size and
the dry state of the skin of the calf, the membranes, and the wall of the
womb. These dry surfaces stick with such tenacity that no attempt at
traction leads to any advance of the calf out of the womb or into the
passages. When the fetus is advanced the adherent womb advances with it,
and when the strain is relaxed both recede to where they were at first. The
condition may be helped somewhat by the free injection of oil into the
womb, but it remains impossible to extract the enormously bloated body, and
the only resort is to cut it in pieces and extract it by degrees. (See
"Embryotomy," p. 202.)
RIGID CONTRACTIONS OF MUSCLES.
In the development of the calf, as in after life, the muscles are subject
to cramps, and in certain cases given groups of muscles remain unnaturally
short, so that even the bones grow in a twisted and distorted way. In one
case the head and neck are drawn round to one side and can not be
straightened out, even the bones of the face and the nose being curved
around to that side. In other cases the flexor muscles of the fore legs are
so shortened that the knees are kept constantly bent and can not be
extended by force. The bent neck may sometimes be sufficiently straightened
for extraction by cutting across the muscles on the side to which it is
turned, and the bent knees by cutting the cords on the back of the shank
bones just below the knees. If this fails, there remains the resort of
cutting off the distorted limbs or head. (See "Embryotomy," p. 202.)
TUMORS OF THE CALF (INCLOSED OVUM).
Tumors or new growths grow on the unborn calf as on the mature animal, and
by increasing the diameter of the body render its progress through the
passage of the pelvis impossible. In my experience with large, fleshy
tumors of the abdomen, I have cut open the chest, removed the lungs and
heart, cut through the diaphragm with the knife, and removed the tumor
piecemeal by alternate tearing and cutting until the volume of the body was
sufficiently reduced to pass through. Where this failed it would remain to
cut off the anterior part of the body, removing as much of the chest as
possible, and cutting freely through the diaphragm; then, pushing back the
remainder of the body, the hind limbs may be seized and brought into the
passages and the residue thus extracted. The tumor, unless very large, will
get displaced backward so as not to prove an insuperable obstacle.
In many cases the apparent tumor is a blighted ovum which has failed to
develop, but has grafted itself on its more fortunate twin and from it has
drawn its nourishment. These are usually sacs containing hair, skin,
muscle, bone, or other natural tissues, and only exceptionally do they show
the distinct outline of the animal.
MONSTROSITY IN THE CALF.
As a monstrous development in the calf may hinder calving, it is well to
consider shortly the different directions in which these deviations from
the natural form appear. Their origin and significance will be rendered
clearer if we divide them according to the fault of development in
individual cases. Monsters are such--
(1) From absence of parts--absence of head, limb, or other organ--arrested
development.
(2) From some organ being unnaturally small, as a dwarfed head, limb,
trunk, etc.--arrested development.
(3) From unnatural division of parts--cleft lips, palate, head, trunk,
limbs, etc.--abnormal growth.
(4) From the absence of natural divisions--absence of mouth, nose, eye,
anus; the cloven foot of ox or pig becomes solid, like that of the horse,
etc.--confluence of parts which are rightfully separate.
(5) From the fusion of parts--both eyes replaced by central one, both
nostrils merged into one central opening, etc.--confluence of parts.
(6) From unnatural position or form of parts--curved nose, neck, back,
limbs, etc.--lack of balance in the growth of muscles during development.
(7) From excessive growth of one or more organs--enormous size of head,
double penis, superfluous digits, etc.--redundancy of growth at given
points.
(8) From imperfect differentiation of the sexual organs--hermaphrodites
(organs intermediate between male and female), male organs with certain
feminine characters, female organs with certain well-marked male
characters.
(9) From the doubling of parts or of the entire body--double monsters,
doubled heads, doubled bodies, extra limbs, etc.--redundant development.
(Pl. XIX, figs. 1, 2, 3.)
_Causes._--The causes of monstrosities are varied. Some, like extra digits,
lack of horns, etc., run in families, which produce them with absolute
certainty when bred in the direct line, although they were originally
acquired peculiarities which have merely been fixed by long habit in
successive generations. The earliest horse had five toes, and even the most
recent fossil horse had three toes, of which the two lateral ones are still
represented in the modern animal by the two splint bones. Yet if our horse
develops an extra toe it is pronounced a monstrosity. A more genuine
monstrosity is the solid-hoofed pig, in which two toes have been merged
into one. Another of the same kind is the solid shank bone of the ox, which
consists of two bones united into one, but which are still found apart in
the early fetus. Though originally acquired peculiarities, they now breed
as invariably as color or form.
Other monstrosities seem to have begun in too close breeding, by which the
powers of symmetrical development are impaired, just as the procreative
power weakens under continuous breeding from the closest blood relations. A
monstrosity consisting in the absence of an organ often depends on a simple
lack of development, the result of disease or injury, as a young bone is
permanently shortened by being broken across the soft part between the
shaft and the end, the only part where increase in length can take place.
As the result of the injury the soft, growing layer becomes prematurely
hard and all increase in length at that end of the bone ceases. This will
account for some cases of absence of eye, limb, or other organ.
Sometimes a monstrosity is owing to the inclosure of one ovum in another
while the latter is still but a soft mass of cells and can easily close
around the first. Here each ovum has an independent life; they develop
simultaneously, only the outer one having direct connection with the womb
and being furnished with abundant nourishment advances most rapidly and
perfectly, while the inclosed and starved ovum is dwarfed and imperfect
often to the last degree.
In many cases of excess of parts the extra part or member is manifestly
derived from the same ovum, and even the same part of the ovum, being
merely the effect of a redundancy and vagary of growth. Such cases include
most instances of extra digits or other organs, and even of double
monsters, as manifested by the fact that such extra organs grow from the
normal identical organs. Hence the extra digit is attached to the normal
digit, the extra head to the one neck, the extra tail to the croup, extra
teeth to the existing teeth, and even two similarly formed bodies are
attached by some point common to both, as the navels, breastbones, backs,
etc. (Pl. XIX, figs. 1, 2, 3.) This shows that both have been derived from
the same primitive layer of the embryo, which possessed the plastic power
of building up a given structure or set of organs. An inclosed ovum, on the
other hand, has no such identity or similarity of structure to the part
with which it is connected, showing an evident primary independence of both
life and the power of building tissues and organs. The power of determining
extra growth along a given natural line is very highly developed in the
early embryo and is equally manifest in the mature examples of some of the
lower forms of animal life. Thus a newt will grow a new tail when that
member has been cut off, and a starfish will develop as many new starfishes
as the pieces made by cutting up the original one. This power of growth in
the embryo and in the lower form of animals is comparable to the branching
out again of a tree at the places from which branches have been lopped. The
presence of this vegetablelike power of growth in the embryo accounts for
most double monsters.
The influence of disease in modifying growth in the early embryo,
increasing, decreasing, distorting, etc., is well illustrated in the
experiments of St. Hilaire and Valentine in varnishing, shaking, or
otherwise disturbing the connections of eggs and thereby producing
monstrosities. One can easily understand how inflammations and other causes
of disturbed circulation in the womb, fetal membranes, or fetus would cause
similar distortions and variations in the growing fetus. It is doubtless
largely in the same way that certain mental disturbances of a very
susceptible dam affect the appearance of the progeny. The monstrosities
which seriously interfere with calving are mainly such as consist in extra
members or head, which can not be admitted into the passages at the same
time, where some organ of the body has attained extra size, where a
blighted ovum has been inclosed in the body of a more perfect one, or where
the body or limbs are so contracted or twisted that the calf must enter the
passages doubled up.
_Treatment._--Extraction is sometimes possible by straightening the
distorted members by the force of traction; in other cases the muscles or
tendons must be cut across on the side to which the body or limbs are bent
to allow of such straightening. Thus, the muscles on the concave side of a
wry neck or the cords behind the shank bones of a contracted limb may be
cut to allow of these parts being brought into the passages, and there will
still be wanting the methods demanded for bringing up missing limbs or
head, for which see paragraphs below. In most cases of monstrosity by
excess of overgrowth it becomes necessary to cut off the supernumerary or
overdeveloped parts, and the same general principles must be followed as
laid down in "Embryotomy" (p. 202).

These include all general presentations, yet other subsidiary ones will at
once occur to the attentive reader. Thus, in each anterior or posterior
presentation, with the back of the calf turned downward or to one side, the
case may be complicated by the bending back of one or more members as a
whole or at the joint just above the shank bones (knee or hock). So also in
such anterior presentation the head may be turned back.
_Head and fore feet presented--Back turned to one side._--The calf has a
greater diameter from above down (spine to breastbone) than it has from
side to side, and the same is true of the passage of the pelvis of the cow,
which measures, on an average, 8-7/10 inches from above downward and 7-9/10
inches from side to side. Hence the calf passes most easily with its back
upward, and when turned with its back to one side calving is always tardy
and may be difficult or impossible. The obvious remedy is to rotate the
calf on its own axis until its spine turns toward the spine of the cow. The
operation is not difficult if the body of the calf is not yet fixed in the
passages. The presenting feet are twisted over each other in the direction
desired, and this is continued until the head and spine have assumed their
proper place. If the body is firmly engaged in the passages the skin of the
whole engaged portion should be freely lubricated with lard, and the limbs
