a mixture of parts, or an evident attempt towards it, is less common than those 

 we have mentioned. Mr. Hunter has given several instances of it in the neat cat- 

 tle, where the mixture of male and female organs was in different degrees. In 2 

 free-martins, imperfect testicles were found in the situation of the ovaria ; and, in 

 a 3d, an appearance like both testicles and ovaria was met with, close together, in 

 the situation of the ovaria. He also gives the dissection of an hermaphrodite ass ; 

 in which there were substances resembling both testicles and ovaria in the abdo- 

 men. Mr. Hunter never met with an instance of this kind in the dog ; and I 

 have not found one in any record which I have examined. I shall therefore state 

 the following history of a case which has fallen under my own observation, as it 

 proves, that a mixture of the generative organs sometimes occurs, in a species of 

 animal in which it had not been before met with ; and, as the dog is more domes- 

 ticated than almost any other quadruped, the occurrence must be rare indeed, 

 otherwise it could not have escaped notice. 



A favourite dog of Lord Besborough's, which had lived in the family for many 

 years, was observed to have no teats, and never to have been in heat, though, to 

 appearance a perfectly formed bitch in all other respects : those circumstances being 

 made known to Sir Jos. Banks, he requested, that when the animal died, it might 

 be sent to him. This happened last summer ; and I had an opportunity of exa- 

 mining the organs of generation, which exhibited the following appearances. 

 There was not the smallest appearance of teats on the skin of the belly : so that, 

 in this particular, it differed both from the male and female ; nor was there the 

 least trace of any thing like the gland of the breast, under the skin. The clitoris 

 was very large, being three-quarters of an inch long, and half an inch broad ; the 

 orifice of the meatus urinarius was unusually large, as if it was intended for a 

 common passage to the bladder and vagina ; so that the external parts were only 

 the clitoris, meatus urinarius, and rectum. Internally, in the situation of the 

 ovaria, were 2 imperfectly formed small testicles, distinguished to be such by the 

 convolutions of the spermatic artery ; from these passed down an impervious chord, 

 or vas deferens, not thicker than a thread, to the posterior part of the bladder, 

 where they united into one substance, which was nearly 2 inches long, and termi- 

 nated behind the meatus urinarius. The other parts of the animal were naturally 

 formed. When the testicles were cut into, they appeared to have no regular glan- 

 dular structure. In this animal, the clitoris was the only part of the female organs 

 that was completely formed. What rendered the parts a decided mixture of male 

 and female organs was, the testes being in the place appropriated for the ovaria 

 and the ligamentous substance, to which the vasa deferentia were connected, some- 

 what resembling an impervious vagina. The clitoris, in this instance, could not be 

 considered as an imperfect penis, since the bone, the distinguishing mark of the 

 dog's penis, was wanting. 



In Haller's account of hermaphrodites, before-mentioned, there is the history 

 of a kid, in which there was a mixture of male and female organs, illustrated by
