MALE ORGANS OF PERISSODACTYLA. 663 



it is half an inch thick at its commencement, but expands as 

 it extends along the muscle, the fleshy fasciculi of which are 

 inserted into the tendon in an obliquely converging, or semi- 

 penniform manner. As the tendon augments in breadth, it 

 diminishes in thickness, converging towards its fellow, which it 

 meets and joins two inches before the anterior termination of the 

 fleshy portion. The two united flattened tendons beyond are 

 gradually converted into a round chord of ligamentous substance 

 an inch in diameter. This chord, ib. /, /", glides through a strong 

 slightly elastic aponeurotic sheath, along the median groove of 

 the dorsum penis ; it is connected with the inner surface of the 

 sheath by a highly elastic cellular tissue; the chord maintains its

ropelike character along the basal third of the glans, then sub- 

 sides, expanding laterally, and is finally lost upon the firm cap- 

 sule of the glans. There is no e os penis.' A pair of ' retractores 

 penis,' fig. 520, , t, are inserted into the under part of the base 

 of the glans. The nerves of the dorsum penis, the arteries, and 

 trunks of two large plexuses of veins, pass beneath the bridge 

 formed by the confluence of the tendinous and muscular parts of 

 the ' levatores penis ' and between the two suspensory ligaments 

 of the penis. These ligaments are an inch in breadth, and one- 

 third of an inch in thickness at their origin from the ischio-pubic 

 arch a little in advance of the ligamentous attachments of the 

 crura corporis cavernosi. The total length of the undistended 

 penis is three feet nine inches ; the circumference of the prepuce 

 is one foot five inches. The preputial orifice is two feet ten inches 

 from the vent. The substance of the large reflected preputial fold 

 of soft integument, fig. 520, p, r, is from half an inch to two-thirds 

 of an inch in thickness, and consists of a moderately compact 

 cellular corium, with a delicate epiderm, minutely rugose, in the 

 transverse direction, and perforate or punctate with the pores of 

 the mucous follicles which are very regularly dispersed at in- 

 tervals of about a quarter of an inch. The glans penis, ib. gl 9 

 is a long and slender subcompressed cone with a truncate apex ; 

 in its flaccid undistended state, it is one foot in length : the pre- 

 puce is reflected upon its base at the same transverse or circular 

 line, and there is no frasnum. The apex, ib. a, is not simple, but 

 resembles a mushroom on a thick peduncle, fig. 521, /, projecting 

 from an excavation at the end of the glans with a thin wall or 

 border, ib. e, e, like a second prepuce ; but this is of the same 

 structure as the rest of the firm surface of the glans. On each side 

 of the base of the glans, and rather towards its under part, there
