Notes of the post mortem appearances of a Cynncpphalus Papion, which died at 

 the Menagerie in Philadelphia. 



By Edward Halloweli, M. D. 



The animal is young, measuring about fourteen inches in length. 



Head — Brain not examined. 



Thorax. — The upper lobes of the right lung are firmly adherent to the pleura; 

 the whole of this portion of the lung is infiltrated with tubercular matter, firm to 

 the touch, and having a white caseifornn appearance ; the entire mass measures 

 three inches in length, by two in breadth, French measure; the lowest lobe of this 

 lung is of a brick dust red colour; presenting numerous tubercles immediately 

 beneath the pleura, varying in size from that of a grain of sand t) two lines and 

 a half ; the two lobes of the opposite lung are slightly adherent, and studded with 

 tubercles, the largest of which measures five lines in its greatest extent; the gene- 

 ral colour of this lung is reddish-brown. The tubercular infiltration above men- 

 tioned, occupies the whole of the uf)per lobes o*" the right lung which have a uni- 

 formly dull white colour throughout, and are resisting ^o the touch; the lowest 

 lobe is partially hepatized, containing a number of tubercles, most of which are 

 observed immediately beneath the pleura; the base ol the right lung is partially 

 adherent to the diaphragm. ') here are two distinct lobes to the left lung, the 

 upper presenting a slight fissure upon its anterior border; the tissue of both is im- 

 perfectly crepitant, containing numerous tubercles deposited near the surface of 

 the lung beneath the pleura; the largest of these measures four Imes in d atrieter; 

 the lining membrane of the cesophagus is pale, having a slight rosy tint and 

 appears healthy ; the mucous membrane of the trachea and bronchi is pale ; the 

 bronchial glands are tuberculous, but not remarkably enlarged. Hta/i — The 

 two surfaces of the pericardium are adherent throughout, their separation 

 requiring some effort ; the external surface of the heart is covered in nearly 

 its whole extent with a thin layer of false membrane of a slightly yellow colour, 

 giving it an appearance of roughness ; the general colour of the pericardium is 

 pale with a tinge of redness ; upon the surface of the heart, imbedded in its 

 tissue, innmediately beneath the peric irdiuin are several snnall tubercles, having 

 the sanne aspect as those of similar dinnensions found in other organs ; the ven- 

 tricles are ennpty containing no coagula. 



Abdomen. — The liver is divided into four lobes, one of which presents two 

 small subdivisions; it is of a brownish red colour; about a dozen scattered 

 tubercles, the largest having the size of millet seed are observed in its subperi- 

 toneal tissue; it measures four inches transversely, by two inches four lines in 

 its longitudin .1 d ameter. and fourteen lines in depth ; its tissue when cut into 

 presents nothing remarkable; the ga/l-b/adder is moderately distended with bile 

 of a brown colour and almost fluid consistence. S/jlctn — The spleen measures 

 two inches ten lines in length and fifteen lines in its greatest breadth ; it pre- 

 sents upon its convex surface numerous elevations, caused by the deposition 

 of tuberculous matter within its tissue, giving it a highly bosselated appear- 

 ance, resembling in some degree the cancerous dep sits observed in the human 

 liver; the largest of these measures seven lines in diameter, and is elevated 

 about three lines above the surface of the spleen; the tuberculous deposite 

 resembles in colour that of the lung, and appears to be composed of numerous
