" Thereis a peculiar structure connected with the salivary system, 

 which appears to have been hitherto unnoticed in this or any other 

 raammiferous animal. The secretion of the submaxillary gland, a 

 gland of very large size, is leceived prior to its expu]sion into a 

 sac, in which it becomes very tenacious ; the sac is about the size 

 of a french-bean, and receives the saliva by four or five short ducts 

 entering at its posterior part and having valves at their orifices, by 

 which a retrograde course of fluids is prevented from the sac to the 

 gland. A long duot is continued from the anterior extremity of the 

 sac, and terminates by a minute orifice iramediately behind the syni.

" The epiglottis rises behind the soft palata into the posterior nares, 

 nor does the structure appear to admit of its ever passing beneath 

 thatpartj it is deeply notched at the fl/3ex. The mnscn\aT jM7-ietes 

 of the pharynx and ccsophagus are very thick, for from the nature of 

 the teeth, small, conical and wide apart, the food can undergo but 

 little comminution in the mouth, and hence the necessity of addi- 

 tional povver for propelling imperfectly divided substances Into the 

 stomach, and of a structure analogous to the gizzards of birds for 

 completing their trituration in that cavity. The rings of the tra- 

 chea overlap each other behind, but do not coalesce : they are irre- 

 gular in their size. 



" The thyroid glands are of the size of french-beans, and united 

 by a very thin transverse band, likę a connecting vessel. 



" No morbid appearances were met with in either of the preced- 

 ing dissections."
