Having opened the abdomen, and removed the intestines, I extracted the 

 uterus and bladder, because the partes generation! inservientes are the most 

 noticed in comparative anatomy. I could not get the vasa praeparantia preserved, 

 and only got out the uterus itself, with the cornua, ovaria, and part of the liga- 

 menta lata. It is not unlike the uterus of such animals as bring forth several at 

 one litter; for on inflating it, I perceived several protuberances arise, as if they 

 had been so many cellules, such as bitches, cats, hares, &c. have, for contain- 

 ing the several foetuses, with their proper placentas and involucra; which might 

 have induced me to believe they bring forth more than one at a time, had not 

 authors affirmed the contrary. For whereas the uterus of such animals as bring 

 forth only one at a time, is proportionably large, and the cornua small ; here 

 the body of the uterus was so small, that one would think it only a bivium to 

 the two. cornua; for after the tube had passed the corona, which is pretty strong 

 and close, I observed the cornua to swell on every side by inflation, leaving a 

 a sulcus in the middle, and these diff^erent protuberances to arise with depres- 

 sions, as so many interstices between them. Each of the ovaria was the size 

 of a large apple, with the ova fitly distinguished by their proper membranes, 

 being for the most part about the size of a small pea, and all involved within a 

 common thin and pellucid tunicle, through which they shone; but to defend 

 them there was provided a loose thick wrinkled tunicle, which I could remove 

 at pleasure, it nowise adhering to the ovaria, but fluctuated above them, and 

 proceeded from the cornua. I opened one or two of these ova, and found them 

 filled with a thin limpid substance, not unlike hydatides, but that the humour 

 was more viscous. The extremities of the cornua, which received the ova, 

 were very narrow, for when I had inflated the uterus, it retained the air for 

 some time, without passing immediately out by the cornua; though afterwards, 

 when I had strictly tied the vagina, I observed the air insensibly slide out, and 

 now and then I could see small bullulae arise toward the ovaria. The vagina 

 was very small and narrow, not admitting above two or three fingers: its inner 

 surface was whitish, and moistened by a certain kind of mucus, and all full of 

 plicae or wrinkles. 



The bladder is rounder than that of an ox, and much larger than Dr. Moulins 

 would have it; for he says, it is much about the size of an ox bladder, but I 

 find, when gently inflated, it can contain 6 or 7 English gallons. It is very 

 strong, and the vessels appear very prettily dispersed through the tunicles, 

 which I could have easily separated, but did not design to lose it. The ureters 

 were about half an inch diameter, and I could have easily discovered their inser- 

 tion, if I had not designed to preserve the bladder. Both uterus and bladder
