The subcervicaland prespermatic portions can be removed without disturbing them. Xature of prostatic hypertrophy.—That prostatic enlargement is atrue hypertrophy is very improbable since it begins at a period whenthe functional activity of the gland is on the decrease while the hyper-trophies occurring in all other glandular organs are at a much earlierperiod. Furthermore, the hypertrophy is not diffuse but occurs indistinct well-defined areas. In great prostatic enlargements an. ^ Fig. J.—The hypertrophy here is advanced still further than that seenin H and I. The central portion is entirely replaced by the hypertrophiedtissue while the peripheral portion assumes the role of a thickened capsulein the periphery. The ejaculatory ducts are seen towards the posteriorsurface. astonishing number of these spheroids may be present. Each ofthese, however, does not represent a primarj^ tumor formation. Thegrowth in an area undergoing hyperplasia is not always equal atevery point, the result of this inequality being the production ofrmmerous spheroids, the direct descendants of one primary focus ofactivity. The size of the h^pertrophy depends upon the number andvolume of these tumor formations. These spheroidal tumors vary in their composition. Most frequentlythey are fibro-myo-adenomata, but aU variations from an almostpure adenoma to pure myoma or fibroma are encountered. The puremyomata and fibromata are unco
