Mr. Home's Observations on the 
mals ; it is of considerable length, and tapers towards the end of 
the glans, which is extremely small, and pointed. The testicles 
are contained in a very pendulous scrotum, situated upon the 
belly, before the penis ; the scrotum is more commonly drawn 
up to the abdominal muscles, but at other times it hangs down 
several inches in length ; this appears to be one of the effects 
of the animal's desires, at least it was so in one of the male 
kanguroos at the menagerie at Richmond ; for when the ani- 
mal was at rest the scrotum was drawn up, but when the penis 
was brought into the state of erection, the scrotum became ex- 
tremely pendulous. 
In the female, the external parts of generation are situated 
close to the anus, there being one common verge of the exter- 
nal skin to both these canals, which are only separated from 
one another by means of a septum of no considerable thick- 
ness. This common verge of the external skin projects above 
two inches beyond the bones of the pelvis, and admits of a 
good deal of motion. 
From this structure, both in the male and female, it is 
evident that they copulate in the same way as most other 
quadrupeds. 
In giving an anatomical description of the female organs of 
the kanguroo, I shall, with a view to avoid unnecessary detail, 
describe them first in their most natural, or unimpregnated 
state, and afterwards take notice of the changes they undergo 
during pregnancy, and in the time of parturition. In this de- 
scription I shall be the less minute, as accurate drawings of the 
parts are annexed, which will explain whatever may appear to 
be deficient in the description. 
At the external orifice of the vagina is situated the clitoris,
