ing a cape through it, tied this on one side, he would have it 

 puckered and constricted on that side, and thrown into cells 

 similar to those of the colon on the opposite side. Such is the 

 structure of the cornua of the uterus in the hind and doe. In 

 other animals it is different ; for there the cells are either much 

 larger, or they are entirely wanting. The cells of the cornua 

 uteri of the hind and doe, however, are not all of the same 

 size -, the first that is met with is much larger than any of the 

 others ; and here it is that the conception is generally lodged. 



As the uterus, tubes, or cornua, and other parts appertain- 

 ing in the human female are connected with the pubes, spine, 

 and surrounding structures by the medium of broad and fleshy 

 membranes, by suspensory bands, as it were, which anatomists 

 have designated by the name of bats' wings, because they have 

 found that the uterus suspended in this way resembled a bat 

 with its wings expanded, so also are the cornua uteri, together 

 with the testes [ovaries], on either side, and all the uterine 

 vessels, connected with the neighbouring parts, particularly 

 with the spine, by means of a firm membrane, within the folds 

 of which are suspended all the parts that have been men- 

 tioned, and which serves the same ofiice with reference to these 

 uterine structures as the mesentery does to the intestines, and 

 the mesometrium to the uterus of the fowl. In the same way, 

 too, as the mesenteric arteries and veins are distributed to the 

 intestines through the mesentery, are the uterine vessels dis- 

 tributed to the uterus through the membrane in question ; in 

 which also certain vessels and glands are perceived on either 

 side, which by anatomists are generally designated the testicles 

 [the ovaries.] 



The substance of the horns of the uterus in the hind and 

 doe is skinny or fleshy, like the coats of the intestines, and 

 has a few very minute veins ramified over it. This substance 

 you may in anatomical fashion divide into several layers, and 

 note different courses of its component fibres, fitting them to 

 perform the several motions and actions required, retention, 

 namely, and expulsion. I have myself frequently seen these 

 cornua moving like earthworms, or in the manner in which the 

 intestines may at any time be observed, twisting themselves 

 with an undulatory motion, on laying open the abdomen of a 

 recently slaughtered animal, by which they move on the chyle
