left ventricle ends blindly. The right ventricle opens at its anterior part^by an opening, 

 which it is hard to see from the inside, into an anterior expansion. A rod G nun. in 

 diameter, introduced from in front, fully distends the passage. I regret that 1 was not 

 present when the roaring sac was opened by the primary incision at the autopsy. It 

 was described as immense, extending over the front of the neck and the top of the chest 

 outward as far as the coracoids. The portion still connected with the specimen passes 

 up under the hyoid where it is sacculated. The communication with the larynx is just 

 to the right of the median line. 



The Tongue. 



This organ seems hardly to have received the attention it deserves. It is longer and 

 broader than in man. While strikingly similar, it presents some noteworthy differences. 

 As in the human tongue the anterior two thirds of the dorsum are to be sharply distin- 

 guished from the posterior one, which has the papillae circumcallatae near its front and 

 is occupied by adenoid tissue and mucous glands. In " Gumbo " the anterior two thirds 

 besides the filiform papillae have very nitiny fungiform ones, especially near the tip. 

 What is remarkable is, that the characteristics of the dorsal mucous membrane are 

 prolonged at the tip onto the inferior sui'face for 5 mm. or more. In the posterior third 

 there is an oval swelling of the whole tongue in the middle, while in man there is a 

 median furrow. The circumvallate papillae, some seven in number, are arranged rather 

 like aT than a V. In some cases two papilhie are surrounded by the same mote. The 

 surface of the very posterior part is very irregular, owing to accumulations of adenoid 

 tissue. Very striking is the large number of orifices looking like small pin-holes to the 

 naked eye. Whether these are really the openings of large ducts or simply little cavities 

 between adenoid collections can be determined only by the microscope. The papillae 

 foliatae are more strongly developed than in man. These constitute a system of trans- 

 versely placed ridges and furrows extending along either side of the tongue just in front 

 of the end of the anterior pillar of the fauces. This system describes a marked curve 

 with an inward convexity. From this in the anterioi- part of the posterior third of the 

 tono-ue among the large papillae and .somewhat in front of them is a curious system of 

 curved raised lines suggesting that of the tips of the fingers. 



The Caecum. 



The caecum (pi. 8.) was the only part of the intestines saved. The vermiform 

 process was divided some six inches from its origin, so that its length is not known. The
