THE SEXUAL ORGANS. 237 



them by their tubular form, and the frequently much convoluted 

 course of the glandular vesicles, which are 0*04 — O'OS'" wide. 

 More simple forms of glands of this kind (fig. 161) are occa- 

 sionally met with intermixed with the others, and in the pars 

 prostatica, instead of them, we find minute mucous follicles, 

 similar to those which have been before described as occurring 

 in the cervix vesicae. The epithelium, both in the vesicles of 

 the " glands of Littre" and in the excretory ducts, 1 — 2'" long, 

 which are directed forwards, penetrating the mucous membrane 

 obliquely, is cylindrical; in the former situation, however, 

 more or less approaching the tesselated form (fig. 261) ; the 

 secretion is common mucus, which in dilatations of the glan- 

 dular follicles is, not unfrequently, collected in some quantity. 

 Some minute, inconstant fossse of the mucous membrane have 

 been termed lacunae Morgagni, in which I have been unable to 

 detect anything of a glandular nature. The fascia penis, a 

 tissue abounding in finer elastic fibres, surrounds the penis, 

 from the root to the glans, being, in the former situation, in con- 

 nexion with the perineal fascia, and that of the inguinal region, 

 and also contributes to the formation of the suspensory ligament 

 of the penis, a structure very rich in true elastic tissue, which 

 extends from the symphysis to the dorsum penis. Externally 

 it is continuous, without any line of demarcation, with the skin 

 of the penis, which, up to the free border of the prepuce, a 

 simple duplicature of it, possesses the nature of the common 

 integument; though certainly characterized by its delicacy, 

 and the presence of a layer of smooth muscles in the abundant, 

 fat-less, subcutaneous tissue, a continuation of the tunica dartos 

 (vid. § 34), which extends as far as into the prepuce. At the 

 border of the prepuce the integument of the penis assumes 

 more of the nature of a mucous membrane and is no longer 

 furnished with hairs and sudoriparous glands, although it has 

 well developed papillae; it is still thinner than before, and on 

 the glans is intimately connected with the spongy body, and 

 covered with a softer cuticle (§ 42. fig. 56, 4), always, how- 

 ever, 0-055'" thick. With respect to the sebaceous glands 

 ( gl. Tysonianae), which exist in this situation, and the forma- 

 tion of the preputial smegma, consult §§ 46, 74. 



The arteries of the penis are derived from the pudic, and 

 are peculiar only in the way in which they supply the corpora
