MACACUS SILENUS. 11 



large salivary glands, as large as [those of the] human. An uvula, 

 which I never saw before. The muscles of the larynx very like [those 

 of] the human. The digastricus passes through the stylo -hyoidaeus. 

 It has a trochlearis muscle [of the eye-ball] as in the human. 



The pericardium adheres by a broad surface to the diaphragm, there- 

 fore there is a short vena cava inferior. The heart is not so flat as in 

 the human, but more so than in the quadruped. The auricles are more 

 rounded on their anterior appendixes. There is a fourth lobe to the 

 lungs which lies between the heart and diaphragm, so that the heart 

 was some way from the diaphragm. 



The fundus of the gall-bladder appears in a fissure on the convex 

 surface of the liver; the internal surface is vastly rugous, and the 

 papillae of these rugae are large and hard. 



There is a bone in the penis, in length between the glans and 

 attachment of the prepuce. The tunica vaginalis communicates with 

 the abdomen. 



The length of the small guts are three times the length of the animal 

 from head to heel, and [that of] the great [gut is] just once [the same 

 length]. 



[The Wanderoo (Macacus Silenus).~\ 



In a long-tailed monkey there is one panniculus carnosus that arises 

 from the os humeri just at the insertion of the pectoralis major, and 

 from the fascia that the muscle throws over the biceps. This panniculus 

 passes back with the panniculus carnosus, spreads and is lost in the 

 skin of the back insensibly, taking the same direction with the latissimus 

 dorsi, so that it covers that niusclet The other panniculus carnosus is 

 the platysma myoides ; the anterior of which is as in the human, and 

 is very strong, decussating each other at the chin. Its posterior edge 

 is continued back, and joins the outer part of the occipito-frontalis, so 

 that that part of occipito-frontalis and this portion make but one muscle ; 

 and this muscle is lost in the skin of the neck just above the termination 

 of the other panniculus carnosus ; so that these two panniculi carnosi 

 of each side will make a kind of raphe in the skin down the back. 



The occipito-frontalis, the elevatores auriculae, and the platysma 

 myoides make but one muscle, and this is the reason that those animals 

 can move their ears and skin of their head so much as they do. The buc- 

 cinator muscle makes a bag, just before the masseter muscle, and before 

 the lower jaw. 



The ears are a good deal like the human, but, as it were, irregularly 

 formed, thin and black ; and when the animal is erect, the ear is as in 

 the human as to situation. 



The eyes are as large as the human, and of the same shape. The
