 upper and pofterior edges, and are thicker and foft at the under extremities. 



The trunk of the body confifts of the neck, breaft, back, and belly. The neck is 

 roundifh, and fhorter than the head ; its vertebrae, or chine bones, are not, as in moft 

 animals, connected by a fufpenfory ligament ; the nape is hollowed ; the throat, im« 

 mediately below the chin, is hollowed at its upper part, and protuberant in the middle 

 a little lower down. The breaft is fomewhat flattened both before and behind ; on the 

 fore part there is a cavity or depreflion where it joins with the neck ; the arm-pits are 

 hollow and hairy ; the pit of the ftomach is flat : On the breaft are two diftant, round, 

 protuberanc mammae, or dugs, each having a cylindrical obtufe wrinkly projecting 

 nipple, which is furrounded by a darker coloured circle called the areola. The back is 

 flat, having protuberances on each fide at the fhoulder blades, with a furrow or depref- 

 fion between them. The abdomen or belly is large and protuberant, with a hollow at 

 the navel ; the epigaftric region, or fituation of the ftomach, is flat ; the hypogaftric 

 regions, or fides of the belly, are protuberant ; the groins flattifh and hollowed. The 

 pubis is hairy; the pelvis, or bafon, is wider above, and grows narrower below; the 

 male parts are external and loofe ; the penis cylindrical ; the fcrotum roundifh, lax,. 

 and wrinkled, being divided in the middle by a longitudinal ridge or fmooth line^ 

 which extends along the whole perinaeum : The female parts are compreffed and pro-

 catamenia. There is no. external tail. 



The limbs confift of arms and hands, inftead of fore legs, and of thighs, legs, and

 a foot in length, from the joint of the flioulder to the elbow ; the fore- arm, or cubit, 

 contains two bones, and is obtufely prominent ; the ulna, which forms the principal 

 thick nek of the member, is round, and fomewhat flattened on the infide. The hands 

 are broad, flat, and rounded ; convex on the out fide, or back of the hand, and con- 

 cave on the infide, or -palm. Each hand has five fingers, one of which, named the 

 thumb, is fhorter and thicker than the reft, and is placed at fome diftance from them ; 

 the others are near each other, and placed parallel, the outer or little finger being the 

 fmalieft ; the fecond, named index, or fore finger, and the fourth, called the ring finger, 

 are next in length and in fize ; and the third, or middle finger, is the longeft ; the point 

 of this laft, when the arm and hand hang down, reaches to the middle of the thigh-
