A text-book of veterinary obstetrics : including the diseases and accidents incidental to pregnancy, parturition and early age in the domesticated animals . conical, ramifying, or branched vilh, measuring THE PLACENTA. 91 from 4 to 6-lOths of an inch, \Yhich arc received into the depressions ofthe maternal cotyledons. This ramifying or racemose disposition of thechorial villi is peculiar to the Bovine and Ovine species. The chorialcotyledons are attached to the chorion by a very short, thick andvascular pedicle ; between them and the maternal cotyledons there isalways to be found a small quantity of thick, white, milky-looking fluid—the so-called cotyledonous or uterine milk. According to Schlossberger, this uterine milk should be considered asa fluid analogous to milk or chyle. It contains 88 per cent, of water,To of fat, 0-7 of salts, and 9-6 of a protein substance. In the cotyledonalfluid, as well as in that on the surface of the uterine mucous membraneof a Mare towards the end of pregnancy, Ercolani has demonstratedthe presence of albumin ; in the same fluid he has also proved the exist-ence of amidon, dextrin, and sodium chloride.^.

The reticulated surface of the maternal cotyledons is homologous withthe decuhia scrotina of other mammals; but it possesses a flrmer texture,and usually remains attached until the termination of gestation--allow-ing the fa-tal villi to be withdrawn from it at birth ; it is afterwards We must not overlook the fact, that the txistence of the uterine milk in theliving pregnant animal has been denied by M.
