188 DR. HENEAGE GTBBES. 



corpuscles_, and blood seems to come from the vessels in the 

 trabeculae which open into these spaces, and to circulate through 

 them. It will be seen, then, that although in the arrangement 

 of the component parts of this structure there is a certain 

 resemblance to a lymphatic gland, there is this great difference 

 — in the one a current of lymph passes through the spaces 

 between the cell massss and trabeculse, while in the other there 

 is a current of blood. 



Some of the spaces, especially in the periphery, are filled 

 with red blood-cells ; amongst these are a number of much 

 larger cells, each containing a well-marked nucleus. This 

 nucleus is as large as that of the cells forming the cell masses, 

 but does not stain as deeply. 



In the cell masses the cells are closely aggregated together, 

 and only their nuclei can be made out. 



The large cells are much more numerous in the spaces near 

 the periphery than in the centre. 



In one part of the capsule I noticed a capillary vessel passing 

 through a space lined by endothelium. The capillary was 

 empty, but the space was filled with red blood-corpuscles. 



The above structures were found in the body of an adult 

 male under 30, who died from the effects of an accident. 



The next case I examined was that of a man aged 58, who 

 died from phthisis. 



I found the same structures as in the previous case. The 

 ganglion, however, was much larger, and each ganglion cell 

 contained a large number of yellow pigment granules. 



In this case I found three of the glands described before. 

 They varied in size, two being much smaller than the one 

 found in the first case, while the third was much larger, about 

 double the size. They were, however, identical in structure 

 with the one already described, and all the spaces between 

 the cell masses and trabeculse were filled with red blood- 

 corpuscles, and amangst them large nucleated cells. 



In addition to these I found in this case an oblong body 

 measuring half an inch in length. In structure it exactly 

 resembled a suprarenal capsule.
