Mode of Generation of the Kangaroo. 
which when compared with the size of the other parts may be 
said to be large, and is covered by a prseputium. A little 
way further on in the vagina are two orifices, which are the 
openings of the ducts of Cooper's glands. The vagina itself 
is about an inch and half in length, beyond which it is divided 
into two separate canals, and on the ridge which lies between 
them opens the meatus urinarius leading to the urinary bladder. 
These two canals are extremely narrow for about a quarter 
of an inch in length, and their coats at this part very thick, but 
afterwards they become more dilated ; they diverge in their 
course, and pass upwards for nearly four inches in length; 
they then bend towards each other, so as to terminate laterally 
in the two angles of the fundus of the uterus, of which they 
appear to be an uniform continuation. 
The uterus itself is extremely thin and membranous in its 
coats, infundibular in its shape, and situated in the middle 
space between these canals ; it is largest at its fundus, and 
becomes smaller and smaller towards the meatus urinarius, 
where it terminates; the uterus at that part in the virgin 
state being impervious. 
The same internal membrane appears to be continued over 
the inner surface of the uterus and lateral canals ; it is thrown 
into several folds, forming longitudinal projecting ridges ; one 
of these constitutes a middle line, extending the whole length 
of the uterus, and dividing it into two equal parts. 
The ovaria, as well as the fimbrias, both in appearance and 
situation, resemble those of other quadrupeds ; the fallopian 
tubes follow nearly the same course to the uterus, but a little 
way before they reach it they dilate considerably, forming an 
oval cavity ; the coats of this part are also much thicker than
