seems to be the same in both cases ; in both the same aceta- bula are discovered, and the same viscid and albuminous mucus can be pressed out in both, as it can also in the cow.
In the conception that contains a single foetus, the umbi- lical vessels are distributed to the whole of the caruncules of either horn ; but the one in which the foetus itself is contained, swimming in its crystalline fluid within the amnion, is larger than the other. In the cases where there are two foetuses present, each has its own separate or appropriate caruncles, and does not send its umbilical vessels in quest of nourishment be- yond the cornu in which it is lodged.
In male foetuses, the testes contained in the scrotum, of large size for the age, hang externally. Female foetuses, again, have their dugs in the same situation, furnished with nipples like the breasts of women.
In the compound stomach of the foetus, namely the omasus and abomasus, a clear fluid is discovered, similar to that in which it floats; the two liquids agreeing obviously in smell, taste, and consistency. There is also a quantity of chyle in the upper part of the intestinal tube ; in the inferior portion a greenish-coloured excrement and scybala, such as we find when the animal is feeding on grass. The liver is discovered of con- siderable size, the gall-bladder of an oblong shape, and in some cases empty.
In so far as the order in which the several parts are pro- duced is concerned, we have still found the same rule to be observed in the hind and doe as in the egg, and we believe that the same law obtains among viviparous animals generally.
EXERCISE THE SEVENTY-FIRST.
Of the innate heat.
As frequent mention is made in the preceding pages of the calidum innatum, or innate heat, I have determined to say a few words here, by way of dessert, both on that subject and on the humidum primigenium, or radical moisture, to which I am all the more inclined because I observe that many pride them-
