lace in some cases exteriorto the original envelope, but in most it appears to be within.Concretions of older date seem to lose the beautiful definiteness oftheir structure, and tend to disintegrate. The contents of thesesemi-organized formations appear to be earthy matter (phosphate,with a little carbonate of lime), tinged by the ordinary yellow pig-ment which is so often derived from the blood. We do not thinkthey are developed from the ordinary epithelial particles of thegland, but that the original vesicles are cells of a particular kind,which are produced from organic exudation upon the mucous sur- 3 B 38 ABNORMAL CONDITIONS OF THE PROSTATE GLAND. face, and fill themselves, as their growth proceeds, with successivedeposits of materials, which are probably poured out when theinland is the seat of vascular excitement.* It is most probable thatin ordinarily healthy states these concretions undergo solution atan early period of their existence, yielding up their contents to Fig. 178.

Prostatic concretions magnified. (Dr. H. Jones.) form part of the secietion of the gland. But if this does not occur,and they go on increasing in size, they become the nuclei of, or aredeveloped into, prostatic calculi. They are sometimes very nume-rous, as many as fifty or sixty having been found in an atrophieddilated prostate, which has, in consequence, when examined ptrrectwriy given the sensation of a bag of marbles. The calculi some-times cohere together, and form a large mass, projecting into themembranous portion of the urethra, which becomes in consequencemuch dilated. A remarkable case of this kind has been recordedby Dr. Herbert Barker,t in which twenty-nine calculi, weighingtogether 1,681 grains, were cemented together so as to form asingle concretion, which was nearly five inches long, and of anelongated pyriform shape. The surfaces of these calculi arefaceted from mutual pressure ; they are of a whitish or reddishcolour, of porcellaneous lustre and hardness, with a radia
