upper surface is more or less ridged along its course. The entire 

 ossicle in figure and density may be compared to a small quill pen, 

 wherein runs the corpus spongiosum. 



In the Rhesus Monkey the bone of the penis is relatively solid and 

 less than half in magnitude of that here described.

Previously to dissecting this Monkey I noted that the general colour 

 over all the body is marly brown, produced by banded hairs of brown 

 and black ; the darkest tint appears to be along the middle of the 

 back. Abdomen, chest, and the inner surface of the limbs are more 

 sparsely supplied with hair, and this is shaded off to a rufous brown. 

 Face bare in great part ; but there are a few short bairs of the same 

 colour as the body situate at the posterior edge of the cheeks, and 

 some straggling hairs around the upper lip, besides a moderately 

 strong yellowish-brown beard. The skin of the nose and that of the 

 lower lip incline to dark brown ; but the remainder of the face in the 

 living animal is usually of an intense red or purple hue. This, I may 

 observe, is due to great vascularity ; for it diminishes or is very much 

 subdued in the dead body. 



There is a certain character given to the physiognomy by the eye- 

 brows, which meet in the middle line, these being composed of 

 scattered stiff erect hairs, each about an inch long. Upon the 

 frontal region of the cranium only very short hairs are present, so 

 that it has a bald look. Towards the occiput they increase in number 

 and length, and close to the neck average 3 inches long, becom- 

 ing at the same time very dark in hue. I may as well mention here 

 that the hirsute covering of the shoulders and back agrees with the 

 neck, though shortening on the loins, as also on the limbs. A close 

 examination revealed little or no underfur. 



Respecting the aspect of the head itself, it struck me as compara- 

 ble with a beetle-browed human being, partly on account of the dispo-
