242 THE CAT. (chap. VIII. tremity the external orifice of the urethra. The organ is held suspended from the wall of the abdomen by a fold of integument which is inserted around the glans, forming what is called the piqyuce (Fig. 115). When not sexually active, the penis is bent backwards towards its ex- tremity, a condition which makes the cat " retromingent." A small bone traverses the midst of the distal part of the penis, reaching almost to its extremity'. The surface of the glans is beset with hard papilla:', the points of which are directed towards its base. The corpora cavernosa and the corpus spongiosum are each formed of a spongy mass of fibrous bands, called trabcculce, containing elastic and muscular fibres as well as nerves and arteries. In the intervals of these bands are highly distensible veins, into which a certain number of arteries directly open. It is the capacity for temporary distension by means of such veins which causes these tissues to be spoken of as "erectile.'" The itrefJira consists of a tube of mucous membrane invested b)' organic muscular fibres. It originates at the bladder, upon quitting which it enters a gland to be shortly described as the prostate. In the floor of this prostatic portion of the tube is a small, ridge-like prominence, called the renini moiifaiiuin, in the midst of which is a narrow, slit-like depression, named the nfric/e (xiiiiis j^ocii/aris, or rc>iica j))'Ofro.sYr/i'r' (jland (Fig. 115, ^;.) is a voluminous, prominent, glandular structure surrounding the urethra at its exit from the bladder, and opening ii\.to that canal by numerous apertures at the
