74 _ Mr. Morgan's Description 



garoo, when loaded with its secretions, and at a time when the 

 young within the pouch was several months old ; for, as I have 

 before stated, the condition of these parts is constantly changing 

 at different periods of gestation. At the particular period, how- 

 ever, which I have mentioned, as referring to the animal under 

 consideration, the following appearances were presented. 



On removing the muscle which enveloped the mamma, that 

 part was found, as in the virgin animal, to be composed of two 

 distinct glandular substances, bearing nearly the same relative 

 proportions as in the former instance (tab. S. f. 1.). In form, 

 however, they were somewhat altered ; for the larger gland had 

 now changed from a circular to an oval shape, it was of a pur- 

 plish colour, and possessed of a very high degree of vascularity. 

 The marsupial teat was now found attached to its inner side. In 

 the former instance, when mentioning the dissection of the virgin 

 animal, it will be remembered, that this gland was described as 

 closely confined to the skin of the pouch immediately behind 

 the follicular openings, which led to a central canal in its inte- 

 rior; whereas, it was now found that its cellular connections 

 were comparatively loose, and that its attachment to that part 

 of the integuments, to which it formerly closely adhered, was 

 now formed by the medium of its excretory ducts, which, in- 

 closed within their proper sheath, were collected together and 

 disposed in the form of a fasciculus or cord passing from the 

 inner margin of the gland to the marsupial teat. 



All remains of the follicular apertures in the pouch had disap- 

 peared, the gland was removed from its former situation, and its 

 excretory ducts, formed into a plexus or fasciculated cord, were 

 continued from the gland to the true marsupial teat, exactly 

 through that part of the integuments of the pouch, which, in the 

 virgin animal, was occupied by the aperture I have before 

 alluded to. ,
