of a male Rhinoceros. 14,9 
and in shape and structure like those in the human subject: they 
contained only a small quantity of a ropy fluid. Upon throw- 
ing some coloured wax into the corpora cavernosa of the penis, 
the extremity became expanded, with the meatus urinarius 
placed in the centre ; this expansion was not so considerable as 
is observed in the horse : about three inches below, a second 
enlargement took place, though not so compleat and perfect as 
the first. The penis was curved in its form, with the convex 
side towards the body ; which proves that this animal must be a 
retro-coient : indeed his general structure might have suggested 
tins idea, had not these parts been particularly attended to. The 
contents of the thorax presented nothing worthy of remark. 
The lungs every where adhered to the inside of the thorax, and 
were in a high state of inflammation; which latter circumstance 
was probably the cause of the animal’s death. 
Whilst the animal was living, the eyes always appeared dull 
and watery ; the upper and under palpebrae were scarcely ever 
observed to come together ; the palpebra tertia was frequently 
carried, over the cornea, and corresponded in shape and struc- 
ture to that of the ox. The muscles of the eye-ball were ex- 
actly similar to those of other graminivorous animals : the globe 
of the eye was not larger than that of the sheep; and the 
cornea was much smaller. Upon cutting through the sclerotic 
coat, it was found somewhat harder and thicker than what is ob- 
served in the sheep ; and, upon endeavouring to separate it from 
the choroid, I found an uncommon resistance at the posterior 
part of the eye ; though in other parts, the adhesion between 
the coats appeared less than what takes place in the human 
body. This unusual connection, naturally directed my attention 
more particularly towards it ; when I readily discovered four
