Prof. Leidy exhibited the internal organs of generation of a Hog, whirl. 

 were of an anomalous character, and had been sent to him for examination 



by Dr. S. C. Thornton, of Moorestown, New Jersey. The animal, Dr. Thorn- 

 ton informed him, had been bought for breeding purposes, and from outward 

 appearances was considered as a good sow. The animal was frequently in 

 heat, and as often received the boar. At these periods it would froth at the 

 mouth, and champ in the manner usual under such circumstances in the mil.'. 

 As the animal would not breed, it was fattened up for meat, and when killed, 

 the butcher, surprised at the peculiar appearance of the internal genital org. ins, 

 sent them to Dr. Thornton. The condition of the external organs the latter 

 did not ascertain, as they had not been preserved. 



In the specimen exhibited, the uterus and vagina were about as well devel- 

 oped as ordinarily in the sow, but approaching the usual position of the 

 ovary, the uterine horns abruptly narrowed into an impervious cord extending 

 along the inner edge and included in the peritoneal fold enclosing an epididy- 

 mis. 



A testicle with the epididymis occupied the usual position of an ovary in 

 relation with the uterns. The testicles were equally well developed on both 

 sides, but no traces of ovaries were evident. The body of the testicle measured 

 about an inch and a half long, by one and a quarter broad, and one thick. 

 The interior exhibited the ordinary appearance. The well developed epididy- 

 mis terminated in a vas deferens extending along the course of the uterine 

 horns, enclosed in the fold of the broad ligament, to the anterior wall of the 

 vagina, in which it pursued its way to the incised extremity of the latter. The 

 vaginal portions of the vasa deferentia were enlarged and provided with late- 

 ral caeca. The epididymis and vas deferens were distended with a milky 

 liquid, but this on examination was found to contain no spermatozoa, only 

 epithelial cells and granular matter.

Prof. Leidy directed attention to a few fossil bones lying on the table. One 

 of the specimens, a well preserved tibia, had been obtained by Prof. Hayden 

 from the pliocene formation of Little White River, a tributary of White River, 

 in the Mauvaises Terres of Dakota. A second specimen, a radius, looking as 

 if it might hare belonged to the same skeleton as the former, together with 

 an astragilus, were found by Prof. Hayden in the pliocene deposit of the Nio- 

 brara River, Nebraska. These bones indicate a small robust species of Rhino- 

 ceros not likely to have been the same as the Ilyracodon Nebrascmsis or the 

 Aceratherium octidmtalis, which belong to the miocene formation of the .Mau- 

 vaises Terres They are too small to have belonged to the Rhinoceros cra**u> } 

 whose remains were found in association with two of the specimens. Their 

 relation to R. meridianus of Texas, K. hesperius of California, and A. matutuius 

 of New Jersey is uncertain.
