front of the organ. There were nine transverse septa, from 

 three to five inches in length, quite regular at the anterior 

 extremity, but much less so posteriorly ; the largest were two 

 and a half inches apart. Midway they formed large con- 

 tinuous cells, capable of holding eight ounces or more ; ante- 

 riorly, they were intersected by other septa, forming very reg- 

 uleir cells which would have held from two to four ounces, 

 but posteriorly the cells were very irregular, holding about 

 two ounces. 



The second cavity of the stomach, which must serve 

 merely as a receptacle for water, had a crescentic form, the 

 small curvature measuring seven inches, and the large fifteen. 

 It communicated very freely with the first ca /it y at the dis- 

 tance of four and one half inches from the oesophagus : the 

 opening into the third cavity is smaller, and immediately 

 below this it formed a cul-de-sac which was two inches deep ; 

 midway, it measured transversely on the inner surface, nine 

 and a half inches. In the small curvature there was a smooth 

 space, four inches wide at the left extremity, but diminishing 

 to one inch at the right. Along this space there ran a strong- 

 ly marked muscular band ; it arose on the left side of the 

 termination of the oesophagus, measured there one inch wide, 

 but gradually diminished and terminated at the opening of 

 the second cavity into the third. Thus the opening of 

 the third cavity is drawn up towards that of the oesophagus 

 to receive the cud that has been chewed, and which is 

 prevented from falling again into the first cavity by the 

 united action of the large muscular band in the first cavity, 

 and the small one in the second. The cells of this cavity 

 were much more numerous, and very much smaller than 

 those of the first, with which they were almost directly 

 continuous ; on an average, they would have held from 

 three to four drams, but the largest, which were situated 

 at the left extremity, were from two to four times as large. 

 There were thirteen transverse septa, counting them on the 

 large curvature, but some of these bifurcated and some united 

 towEirds their extremities. These were intersected by two 

 others, four or five inches long and one fourth of an inch wide,
