Of the figures marked 9th day, one shows the foetus, now, 
for the first time, of itself visible to the naked eye, adhering 
near the tail to the placenta in the closest manner ; the navel 
string as yet too short to be visible, as contrary to De Graaf 
as possible. The second shows the same foetus magnified.

lopian tube , on one side of the uterus of the rabbit, with its 
fimbriated orifice opening into abdomen; and its uterine orifice 
opening into uterus ; also the ovarium, and corpus luteum in 
it, projecting above the surface.
