216 SPECIAL HISTOLOGY. 



oval or cylindrical masses, in which the outlines of the cells 

 have frequently coalesced into a single, general contour-line. I 

 have never been able to detect any other membrane surrounding 

 the cells besides the connective tissue of the corresponding com- 

 partment and I have almost always succeeded, by pressure, or 

 the addition of alkalies, in isolating the cells, without bringing 

 into view any special sac. True follicles, I have hitherto seen 

 only in the inner portions of the cortex, in the form of round 

 or oval vesicles 002 — G'03"' in diameter, within which, no 

 cells like those of the cortical cylinders are formed, but only a 

 collection of oil-drops could be recognised, and which I have 

 been inclined to regard as enlarged cells. The contents of 

 the cortical cells normally consist of fine granules of a nitro- 

 genous substance ; but to these are almost always added 

 solitary fat-granules, which in many cases (in the yellow cor- 

 tical substance), exist in such quantity, as entirely to fill the 

 cells, which then assume a deceptive resemblance to those 



of a fatty liver. In the brown 

 layer of the cortex, the cells are 

 entirely filled with brown pig- 

 ment granules. 



The medullary substance also 

 has a stroma of connective tissue, 

 which prolonged from the cor- 

 tical lamellae, pervades the whole 

 interior, for the most part, in 

 more delicate fasciculi, constitu- 

 ting a network with rather nar- 

 row, rounded meshes. In this network lies a pale, fine-granular 

 substance, in which, in Man, by careful manipulation, and in 

 recent preparations, I have almost always noticed pale cells of 

 0008 — 0'1&" } which, in their fine-granular contents, occasion- 

 ally presenting a few fat, or pigment-granules, their frequently 

 very distinct nucleus with large nucleoli, their angular form, 

 and occasionally single or multiple, or even branched processes,

 from the summit of a cortical cylinder ; I, pigment-cells from the innermost layer of 

 the cortex ; c, fat-containing cells, from the yellow cortical layer ; d, a larger cyst filled 

 with fat, from a cortex of that kind (gland-follicle, Ecker) ; e, cells from the medul- 

 lary substance, some with processes ; x 350 diam.
