X. The Dissection of an Hermaphrodite Dog. With Observations on Hermaphro- 

 dites in general. By Everard Home, Esq. F. R. S. p. 157. 



Instances of animals being brought forth, whose organs of generation are pre- 

 ternaturally formed, sometimes occur, and have been commonly called hermaphro- 

 dites ; this term however should be confined to those only in which there is a mix- 

 ture of the male and female organs in the same animal. Examples of this kind 

 have been rarely noticed ; they have been met with at very distant periods of time, 

 and confined to too few species of animals, to afford extensive opportunities for 

 collecting observations respecting them. To this cause must be attributed the 

 little information that has been acquired on so curious and interesting a subject. 



Monstrous productions, having a mixture of the male and female organs, and 

 which deserve the name of hermaphrodites, appear to arise most frequently in neat 

 cattle ; they are now generally known, and have been called free-martins. This 

 compound animal attracted the attention of the late Mr. Hunter ; and a paper of 

 his, containing a description of the organs of generation of different free-martins, 

 to show that they are by no means uniformly the same, or partake equally of the 

 parts belonging to both sexes, is published in the Phil. Trans, vol. 69. To add 

 to these dissections an account of similar formation of the organs of generation in 

 a dog, is the intention of the present paper. The subject having already been 

 considered an object deserving the attention of the r. s., is an inducement for 

 bringing forward new facts, and observations which have been made respecting them.
