 In the specimen examined tliere was no trace of sublingual glands. 

 The parotids are larger than the submaxillaries, but very similar to 

 them in structure. 



The stomach (fig. 2) resembles that of man in general outline; 

 the oesophagus enters it by a narrow orifice far removed from the

phagus. The intestinal canal is about six times the length of the 

 head and body, of nearly the same calibre throughout, without 

 caecum, and suspended typically in the mesentery. The liver (fig. 4) 

 is wide and deeply divided into lobes ; the spigelian lobe bind, the 

 caudate very long, divided at its posterior extremity by the deep 

 renal fossa ; umbilical and cystic fissures well marked ; the gall- 

 bladder large and pyriform, projecting considerably beyond the 

 margin of the right central lobe, on which it is placed. 



The lungs (fig. 6) are large and deeply divided into lobes, the 

 right lung into three, the fissures extending to the root of the lung, 

 the left into two nearly equal lobes ; the azygos lobe well developed 

 and pyramidal in outline.
