In dissecting out the renal artery and vein in a human 

 subject I found some small bodies which I at first thought 

 were lymphatic glands. On hardening and making sections 

 of them, I found that they consisted of different structures. 

 Some of them were small lymphatic glands, differing in no 

 way from similar glands in other parts ; the largest was about 

 the size of a pea, while others were much smaller. 



One round body, about the size of a hemp- seed, turned out 

 to be a ganglion. It was nearly circular in shape, and had a 

 well-marked fibrous capsule, outside this were several nerve- 

 trunks consisting of meduUated nerve-fibres ; the nerve-trunks 

 varied very much in size. Inside the capsule were a large 

 number of ganglion cells, each cell lying in a single capsule 

 formed of a nucleated endothelial membrane. 



Amongst the ganglion cells were a number of nerve-bundles 

 consisting of medullated and nou-medullated fibres. The whole 

 was well supplied with blood-vessels. 



The next structure consisted of an oval body measuring a 

 little over a quarter of an inch in length by an eighth of an inch 

 in breadth. It had a fibrous capsule which varied very much in
