LEMUR MONGOZ. 29 



be called the first stage towards the quadruped's or double-horned 

 uterus. This seems to be exactly the same with the mongoose. 



[ f Woolly Macauco/ Pennant, Lemur Mongoz, Linn.] 



The hair of the mongoose is almost as soft as wool or beaver, and is 

 very thick. The skin is thin, and it is not connected to the muscles by 

 a ductile cellular membrane, but is lined everywhere with pretty white 

 and hard fat. But this is only when the animal itself is fat, so that it 

 degenerates into the adipose membrane as in the human ; yet this fat 

 does not run into the interstices of the muscles, or muscular fibres as in 

 the human, but comes off from the muscles entire with the skin, so that 

 the skin is still loose on the muscles as in other animals. 



At the bottom of the eye there is a light green [pigmentum]. 



The tongue has a part underneath in shape of that of a bird's tongue, 

 so that it might be called double-tongued. 



The contents of the thorax are much as in brutes, only the heart is 

 not quite so pendulous, for the pericardium adheres by a little bit of its 

 surface to the diaphragm, just at the apex of the heart ; for the axis of 

 the heart is much more in the direction of the body than in the human ; 

 and, as the axis of the heart is pretty horizontal, the vena cava above 

 the diaphragm is shorter than common in brutes, but much longer than 

 in the human ; so long as to allow a small lobe of the lungs to pass 

 behind it, and to lie between the posterior part of the heart and the 

 spine. The cartilages of the trachea are complete rings. 



The stomach of a mocock is very spherical, or rather oval, having the 

 oesophagus passing into one side ; and the pylorus answers to the small 

 end of the egg, so that there is little or no small curvature ; by which 

 means the stomach is not bent, or is very little so. The small end of 

 the stomach is not continued so long and small as in the human, so that 

 it is pretty short and obtuse, which makes it more of the vegetable- 

 eater than in man. 



The pylorus or valvular part is not so closely or firmly connected to 

 the spine as in the human. It is a smooth regular stricture or ring, 

 not pushing more into the gut than into the stomach, but is much more 

 like the human than in any other animal. 



The duodenum is shorter than is commonly found in other beasts ; 

 but not so short as in the human or monkey ; and, as it crosses the 

 spine, it is more attached to the ascending part of the colon, but is not 

 attached to the spine or kidney at the loins and for a longer way than 

 in the brute, but not so much as in the former. The ileum passes into 

 the colon upon the right side. The caecum is very long, about 7 inches ; 

 it is small at the blind end, and becomes larger and larger to the colon,
