ANATOMY OF THE STOMACH. 55 



tents towards the oesophagus in the process of ru- 

 mination, the cud being evidently returned into 

 the mouth from this cavity, and not from the 

 second, as in the bullock ; there was also a thin 

 layer passing in an opposite direction, besides 

 some irregular fibres which would give a rota- 

 tory movement to the contents. The most effi- 

 cient muscular power, however, was a large thick 

 band in the posterior parietes ; it was eighteen 

 inches in length, arose near the cardiac orifice, 

 around which it communicated with the small 

 band which went to the second cavity, and was 

 at this part six inches broad ; at the thickest part, 

 midway, it was an inch and a quarter in width, 

 and at the further extremity it became broader, 

 thinner, and was gradually lost in the parietes." 

 " The cells in the first cavity, which serve the 

 animal as a reservoir for water, were arranged in 

 two rows. The first extended fifteen inches from 

 the orifice of the second cavity, along the posterior 

 parietes, towards the left side. Ten transverse 

 and parallel septa were sent off at a right angle 

 from the strong muscular band, varying in length 

 from five to nine inches, and in depth from three 

 fourths to more than two inches, but becoming 

 less and less marked towards the left side, where 

 they gradually disappear. These septa are in- 

 tersected by others which are thinner, for the 

 most part quite regular, and situated about one
