these are crossed in the middle by a perpendicular set, broader 

 and stronger, and so arranged as to resemble the teeth of a comb ; 

 on which account, these last, forming the partition between the 

 two corpora, have been collectively named the pecten. Thus, 

 preternatural distention of the organ, and consequent liability to 

 rupture, are guarded against both laterally and perpendicularly. 

 Seco)idlj/ , the interspaces are filled with a pale-red spongy sub- 

 stance, in which may be distinguished cylindrical processes 

 taking a longitudinal course: these JM. Girard pronounces to 

 be " evidemment musculaires ;" and I see reason for so con- 

 sidering them ; though I think it is a point which demands con- 

 firmation from physiological or experimental inquiry, and not 

 entirely to be decided upon anatomical evidence. Thirdly, these 

 cylindrical bands are surrounded and connected together by a cel- 

 kdar structure, that would appear to be the result or product of 

 some peculiar venous arrangement : at least, the small veins, 

 which are here far more numerous than the arteries, have every 

 where the freest communication with these apparent cells. 



Organization. — The cavernous structure is especially supplied 

 with blood by a large vessel, the internal pudic artery, a branch 

 of the obturator artery, which enters the crus, giving off several 

 small branches to the other parts of the organ. The pudic nerves, 

 two in number, springing from under the ischial arch, are seen 

 entering the corpus at the same place, one before, the other be- 

 hind the artery. The internal pudic veins, which are large and 

 numerous, divide here into two sets, one accompanying the 

 arteries, the other the nerves, after they have quitted the penis. 



THE GLANS PENIS is the large, irregular, fungus-iike 

 protuberance, forming the fore part of the organ, vulgarly called 

 its head. This part puts on a very different appearance when 

 distended from the state in which we find it in the dead animal: 

 it then presents a broad surface anteriorly, surrounded by a pro- 

 minent inflected border, which is turned back for some distance 

 above, but altogether deficient below, where there is a notch or 

 division of the glans. The lateral portions are prominent, incor- 

 porated in one superiorly, separate and divergent inferiorly : 

 posteriorly, they are terminated by a contracted circular part, 

 whose prominent border forms the corona glandis. From the 

 corona extends along the dorsum penis, a flattened substance of 

 an oblong oval figure : this is the posterior or terminating portion 

 of the glans. In the middle of the glans is a prominence, in 

 front, marking the termination of the corpora cavernosa ; and 

 below this is a circular fossa having in its centre the projecting 

 orifice of the urethra. Altogether, the glans may be regarded as 

 a part l>y which the penis is surmounted in order to enable the
