Mr. Cruikshank’s Experiments 
EXPERIMENT XVII. 
Opened a doe the third day after the coitus : the pouting 
parts of the corpora lutea very transparent before the uterus 
was touched; but as soon as the spermatic and hypogastric 
arteries were divided, in order to cut out the uterus, they all, as 
if struck with some shock likq electricity, became opaque. The 
pouting part I believe is the ovum, and stands upon the top of 
corpus luteum ; it is very vascular, particularly at its basis, but 
as soon as perfect, or ready for expulsion, carries no red blood ; 
it continues to grow of itself in utero, without adhering to the 
uterus for two or three days, then takes root, and becomes very 
vascular : nothing in the tubes or uterus. 
EXPERIMENT XVI 1 1. 
Opened another the fourth day in the morning; but it had 
not conceived, and was in the state of one hot. 
EXPERIMENT XIX. 
Opened one in the evening of the fourth day : the appear- 
ances were little different from those of the fifth morning; the 
ova were only less dispersed through the uterus, and all accu- 
mulated about the orifice of the tubes ; the amnion was like- 
wise closer to the chorion. 
EXPERIMENT XX. 
Opened another at the end of the third day, or rather on the 
beginning of the fourth: the ovaria were dark brown; the 
fallopian tubes and uterus almost black, from the great quan- 
tity of blood derived to them at this time ; I opened this uterus
