to discover the Ova of Rabbits. 207 
on the upper edge and in the body, so that the parts all re- 
mained turgid; the spermatics and hypogastrics not cut 
through; the corpora lutea were very vascular, an artery run- 
ning across ramified from both sides, but particularly spent 
itself in the centre ; the upper part of the corpus luteum, or 
centre, was a little concave, like the head of a turned small- 
pock, but no evident foramen : I believe the ova were gone out, 
but I could see nothing of them in the tubes nor uterus ; the 
fimbrise were more vascular than I ever saw them, and wholly 
covered the ovaria; the peristaltic motion of the tubes was 
very evident, and greater than ever I had seen it ; the inner 
surface of the horns was graniform, with white spots ; this I 
suppose decidua, or perhaps corpus glandulosum Everrahdi. 
De Graaf saw the ova in the tubes this day. 
EXPERIMENT XXI. 
Opened a rabbit at six days and a half : ova in the horns of 
the uterus were just begun to fix, but did not adhere by ves- 
sels ; they were very much enlarged compared with the sixth, 
and the side next the uterus had a round rough spot in it, now 
very conspicuous; the chorion and amnion were almost in 
contact with one another ; they were easily turned out of the 
uterus, which embraced them every where loosely, but at the 
bottom ; the corpora lutea now increased exceedingly in vas- 
cularity, and nourished by a large vessel running across the 
tubes ; remarkably pale, as having done their duty ; the gra- 
niform appearance on the uterus internally not observable as 
ip the last.
