MAMMALIA. 51 



vegetables coarsely bruised by a first mastication ; thence 

 they are borne into the second, which is termed the bonnet* 

 the sides of which have laminse resembling those in a honey- 

 comb ; this stomach, which is very small and globular, seizes 

 the food, moistens it and compresses it into little pellets, 

 which then successively ascend to the mouth to be rechewed. 

 The animal remains in repose during this operation, which 

 is continued until all the food received into the paunch has 

 been subjected to it. When thus rechewed it descends di- 

 rectly into the third stomach, called the leaflet on account of 

 its sides having longitudinal laminse resembling the leaves of 

 a book : thence again it passes into the fourth stomach or 

 rennet, whose sides have only wrinkles, and which is the true 

 organ of digestion. Three sections. 



Section I. Euminantia without Horns. 



There are two genera, the genus Camelus and the genus 

 Moschus, Lin., Musk. 



GENUS CAMELUS, Lin. Camel. 



Canines in both jaws ; two pointed teeth implanted in the 

 incisive bone; inferior incisives to the number of six; eighteen 

 or twenty molars ; upper lips tumid and cleft ; neck long ; 

 instead of the large hoof flattened upon the internal side, which 

 invelopes the whole inferior portion of each toe, and which 

 determines the figure of the ordinary cloven foot, they have 

 merely one small one which adheres to the last phalanx, and 

 is of symmetrical form ; large masses of cells cover the sides 

 of the paunch. Two subgenera. 



SCBGENUS CAMELUS, Cuv. Camel proper. 



Toes united below, nearly to the point, by a common sole, 

 horny and favourable to progression upon sand ; lumps of fat 

 upon the back ; a second canine in the under jaw ; four mam- 

 mae. There are camels with one and camels with two humps. 

 [Old Continent.] 



SUBGENUS AUCHENIA, Illig. Lama. 



Toes separate ; no lumps ; no second canines in the under 

 jaw ; no mammse ; size much less than in the Camel. [New 

 Continent.]
