224 NATURAL HISTORY OF 



subsequently compared with those of specimens of the Cape 



pigeon, afterwards obtained, with the following results : — 



The entire length of the alimentary canal in Fulmarus 



glacialioides I found to be 85 inches, and that of the 



intestinal tract, taken by itself, 74*5 inches. The caeca 



measured three lines in length, and were situated two inches 



above the anus. The stomach was distinctly divided into a 



cardiac and a pyloric portion, separated by a short and 



narrow interval. Of these portions, the cardiac division 



possessed a comparatively feeble muscular coat, and was 



remarkably glandular ; while the pyloric, of a somewhat 



flattened spheroidal form, was extremely muscular. The 



former I found distended with a firm mass of semi-digested 



ship-biscuit ; while the latter contained the two mandibles 



of a small Cephalopod. In the Cape pigeon, on the other 



hand, the length of the entire alimentary canal was 46 



inches ; that of the intestinal tract 34*5 inches. The 



oesophagus enlarged much more abruptly to form the cardiac 



portion of the stomach than was the case in the Fulmar ; 



and the muscular coat of that portion was considerably 



thicker, so that the gastric glands were not visible through 



it. The pyloric division was much more feebly developed 



than in the Fulmar, but the diameter of the intestinal canal 



was considerably greater than in that species. The stomach 



of one of the specimens examined contained ship-biscuit, 



and that of another a piece of pork-rind, so large that it 



must have distended the oesophagus greatly in its passage 



downwards. 



The wind freshened up again in the course of the forenoon, 

 so that we made good "way throughout the day. It lasted on 

 the 15th until the evening, when it died almost completely, 

 and there was a cloudy sky, with a good deal of fog along the
