Not illustrated. 1893 Excerpt: ...epithelial cells, and the characteristic prostatic concretions or amyloid bodies, which are yellowish in color, spherical or triangular in form, and concentrically striated. These concretions appear to be composed of an albuminous substance in combination with a second which corresponds to lecithin (Fiirbringer, Posner). On standing for twenty-four hours the semen separates into an upper clear fluid and a thicker, opaque lower stratum; the former contains few morphological elements, while in the lower layer these are very abundant. Subsequently, after prolonged standing, two varieties of crystals are frequently encountered, those composed of ammonio-magnesium phosphate and the so-called spermatic crystals. According to Fiirbringer, the latter are formed probably by the action of the semen on the prostatic secretion: since these crystals are found almost constantly, after death, in the fluid of the prostate, and not within the contents of the seminal vesicles, they are more appropriately termed prostatic crystals. They occur usually as prisms or pyramids, colorless, or of a slight amber tint, and break readily on slight pressure. THE PENIS. The penis consists of three somewhat flattened cylindrical masses of erectile tissue, the corpora cavernosa and the corpus spongiosum, capped by the conical glans, all of which are held together by connective tissue and enveloped by the skin and subcutaneous tissue. The two cavernous bodies are enclosed within a stout fibrous envelope, the tunica albuginea, which reaches a thickness of about 217 i mm., and is composed of closely interwoven longitudinal bundles of white fibrous tissue, intermingled with well-developed elastic fibres. Within this common investment each body is Fig. 261. surrounded by an individual sheath of...
