In the separation of the placenta during parturition a quantity of maternal 
vascular tissue comes away therefore with the placenta. 

The Fetus. 
The foetus, a male, was well grown. It measured, from the tip of the nose 
to the end of the tail, 19 inches, and to the end of the hind flipper, 203 inches. 
Its girth immediately behind the pectoral flippers was 15 inches. The bladder 
and urachus were pervious up to the root of the umbilical cord, but I could 
not pass a bristle from the intra-abdominal urachus into the fine tubular urachus 
in the cord itself. The umbilical vein did not divide until it reached the under 
surface of the liver. The umbilical arteries had the usual relation to the side 
of the bladder. The teeth had not cut the gum, but the outlines of the crowns 
of the canines and molars could be distinctly felt through the mucous mem- 
brane. The palpebral fissure was not closed in by a membrane. The third 
eyelid was large. Vibrissze about one inch in length projected from the muzzle 
and eyebrows. , 
The foetus was covered with straight stiffish hairs, the longest of which were 
about half an inch in length, and neither woolly nor fur-like. The hairy coat 
was yellowish fawn-coloured, streaked with dark gray bands and spots. The 
hairs were firmly adherent to the skin, and no loose hairs were found in the 
bag of membranes. When the hairs were pulled out of the skin no under coat 
of wool was to be seen. The hairy coat of the mother was lead-grey in colour — 
on the back of the body and head, but on the back of the fore and hind limbs, 
and at the sides of the neck the general tint was white, with black spots. The 
belly also was white, and marked with numerous irregular black spots. The 
young male, shot at the same time, had a different coloration of the hair. The 
top of the head and back of the body were brown, interspersed with gray 
irregular patches; down the middle of the forehead was a dark-brown stripe, 
with a lighter brown stripe on each side. The belly was ash-coloured, with 
brownish spots at the sides and anal end. 
Several observers have directed attention to the shedding of the hairy coat 
of the foetus of some species of seal, either 7m utero, or immediately after birth. 
Wricut states* that the young of the Phoca variegata of Nituson (Phoca vitu- 
lina) change the first hair (which is whitish-yellow, long, and as it were curly or 
woolly) in the uterus in the first half of June, and the hairs of the new-born 
animals have then the same colour and quality as the hairs of the mother. The __ 
moulted woolly hair is found in the uterus alongside of the young animal. This, 
he says, is consistent with the mode of life of this species of seal, the young of __
