to discover the Ova of Rabbits. 
were eight or nine corpora lute a in one ovarium, and two only 
in the other ; on the side of the two I only found one ovum, 
but twice as large as those on the other side. I observed that 
the redness of the uterus, depended on not losing much of the 
animal's blood ; for when they had been so killed that much 
blood was lost, the fallopian tubes at least and ovaria were 
always pale. 
EXPERIMENT XXV. 
Opened another rabbit at two days and a half after the 
coitus: ovaria impregnated, but found no ova in the tubes, 
nor orifices in the corpora lutea. 
EXPERIMENT XXVI. 
Opened one, third day complete : found about six or seven 
ova in the fallopian tubes, near their end, or about an inch 
within the tube, on the side next the uterus : in the micro- 
scope the ovum appeared as having three coats; the middle 
one perhaps becomes allantois or membrana quarta. 
EXPERIMENT XXVII. 
Opened again another at two days and half : and though 
there were a great many corpora lutea , I could not discover 
any ova ; they were probably too small to be perceived, for on 
the third day complete some of the ova were not perceptible, 
till they were put into a fluid, and viewed in the microscope. 
EXPERIMENT XXVIII. 
Opened one the third day all but two hours : found six ova 
in one fallopian tube, and seven in the other, which corres-
