172 PROBOSCIDIA. 



muscle : its opening into the gut is as large as the little finger. There 

 is no gall-bladder. The lymphatics of the liver are most numerous on 

 the under surface. 



The pancreatic duet is very large, and was filled with a yellow slimy 

 mucus : it enters the duodenum by a proper orifice a little way from 

 the hepatic 1 . 



The spleen is a long, flat body, and lies in the doubling of the epiploon ; 

 its length was 3 feet 10 inches : its greatest breadth was 8 inches. 

 The kidneys are semi-conglomerate, more so than the human, by which 

 means the infundibula are larger. The maininillse do not project much, 

 so that the tubuli are easily injected, and are not larger than in the 

 human subject 2 . 



The thorax is sbort at the fore or lower part, but goes pretty far 

 down or back towards the spine. 



The pericardium adheres to the diaphragm nearly as in the human, 

 but not so closely or firmly, by which means the inferior vena cava is 

 nearly as short as in the human, and also adheres by a vast quantity of 

 strong dense cellular membrane to all the surrounding parts ; as to the 

 sternum and anterior parts of the lungs, &c. 



The heart is broad at the apex, not pointed as in the ox, &c. The 

 vense cavae superior and inferior had [at their meeting in the auricle] a 

 considerable ' valvula nobilis 3 .' The remains of the foramen ovale were 

 distinct. There are two valves at the termination of the vena cava 

 superior, but not sufficient to shut up the whole area. The jugular vein 

 and subclavian of the left side do not cross the thorax to the right, but 

 unite into one trunk, which passes down the left side of the heart, 

 winds round the basis of the left auricle, and opens into the right 

 auricle, as in many other animals 4 . The right subclavian and the two 

 carotids arise by one large common trunk which soon divides into the 

 three above mentioned ; and nearly all at the same place. 



The lungs on the left side are composed of one large lobe ; also that 

 on the right, excepting the small lobe, or process sent in between the 

 basis of the heart and diaphragm behind the inferior vena cava, which 

 is small, from the union of the pericardium to the diaphragm, there 

 being no great space for this process or lobe of the lungs to lie between 

 these parts, which we find generally to be pretty large in most qua-

4 [Most Eodentia, all Marsupialia, Monostremata, birds, and reptiles. Camper 

 does not notice this anatomical character. It is well shown in the dried and injected 

 preparations of the heart of the elephant in the Hunterian Museum.]
