Mr. Cruikshank's Experiments 
P. S. These experiments have been read, and the prepara- 
tions and engravings shewn, in the lectures on the gravid 
uterus, given at Windmill-street, every year since the original 
date of this journal. 
EXPLANATION OF THE PLATE (Tab. IV.) 
It was not thought necessary to delineate the whole uterus of 
the rabbit, as it exactly resembles the uterus of other quadru- 
peds, consisting of a vagina, common to two horns, two fallo- 
pian tubes, and two ovaries. Any one who wishes to see this, 
may see it in De Graaf’s little book, tolerably well executed 
for the age in which he lived : but I am more concerned in his 
first appearances of the ova, than in his general anatomy of the 
uterus of the rabbit; and therefore proceed to explain the copy 
of a plate previously engraved, nineteen years ago. 
The figures marked 3d day, are ova of the fallopian tube, 
found after impregnation on that day. The three first are 
of the natural size ; the three next are magnified, in the 
simple microscope. In all of them the chorion and amnion 
are even now distinct, and in some of them the alla?itois, as 
I suspect. 
The figures marked 3^ day, are ova still more advanced ; 
similar to which I found many in the tubes, many in the 
horns of the uterus. The three first are of the natural size ; 
the two following are magnified also in the simple micro- 
scope. 
The figures marked 4th day, are more enlarged ova in 
the horns of the uterus, loose, not adhering, capable of being
