178 PROCEEDINGS OF THE 



the Firth of Clyde on 10th Sept. last. It had been observed 

 floundering in the shallow water off the red lamps on the Greenock 

 Esplanade, and some boatmen went out to it; after no little diffi- 

 culty it was landed. It was said to weigh about a ton, and lived 

 for some hours out of the water. Its dimensions, taken after 

 death, were as follows: — Length, T 9"; height, 3' 9"; snout to eye, 

 10"; diameter of eye, 4J"; snout to gill-opening, 1' 11"; width of 

 gill-opening, 3"; depth of gill-opening, 6"; snout to pectoral limb, 

 2' 4§"; base of pectoral, 7^"; length of pectoral, 1' 1J"; snout to 

 base of dorsal, 4' 4|"; width of dorsal at base, 1' 11"; height of 

 dorsal, 2' 1"; mouth to vent, 4' 8*; mouth to anal fin, 5' 5"; width 

 of anal at base, 1' 9"; depth of anal, 1' 9". The liver was absolutely 

 crammed with a scolecid worm, Tetrarhynchus reptans. 



II. — On the Viscera of the Porpoise and White-beaked Dolphin. 

 By John Cleland, M.D., F.R.S., &c, Professor of Anatomy in 

 the University of Glasgow. 



This communication consisted of a description of specimens in 

 Dr. Cleland's Museum, prepared from viscera presented to him by 

 Mr. John M: Campbell. 



Stomach and intestines. — The stomach in both species is similar, 

 divisible into three main compartments : a panch, lined with horny 

 epithelium; a digestive stomach, highly rugose and glandular; and 

 an elongated pyloric portion, with thin walls, and communicating 

 with the digestive rugose stomach, by the intervention of a very 

 small compartment. The panch and the second stomach communi- 

 cate with a small opening, guarded by a highly rugose disposition 

 of horny epithelium; and the circumstance that in both the animals 

 examined the panch and gullet contained numbers of clean fish 

 bones, while the succeeding course of the alimentary canal was 

 free from all but pulpy contents, suggested the probability that 

 these animals habitually dispose of the bones of the fish on which 

 they feed by vomiting them. 



In the Dolphin it was noticed that the gall duct was thick-walled, 

 sacculated, and dilated, recalling the condition figured by Camper 

 in the elephant. Unfortunately this part was not preserved in the 

 Porpoise. The whole length of the intestine presents longitudinal 

 rugae, and has a very smooth-surfaced mucous membrane. In
