" The stomach is muscular, small, and glandular, and of the shape 

 of an egg. The duodenum is broad at its origin, and at about &$- 

 inches from its commencement the biliary and pancreatic ducts enter. 

 The gall-bladder is 6 inches long and 2 inches in circumference ; it 

 is attached to the under side of the liver, and, gradually diminishing 

 in diameter, it passes over the stomach, and is inserted into the in- 

 testine, without the intervention of any duct. 



* The testes were large, as were the supra-renal glands and kid- 

 neys. 1 did not observe any difference from the usual structure and 

 proportions in any other parts. 



" The small intestines measured 22 feet 6 inches in length, and 

 were about the thickness of the little finger. There were attached 

 to them two cceca, each measuring about 1 inch 3 lines in length, 

 which were of the same diameter as the intestines. The great intes- 

 tines were somewhat larger than the small. The measurements of 

 the stomach and the intestines were as follows: 



Feet. Inches. Lines. 



Length of the oesophagus 10 



Breadth at the pharynx 1 6 



. irtfundibulum 2 4 



Length of the infundibulum 10 



Breadth at the junction of the infundibulum with 



the stomach 6 



Length of the stomach 4 



Width of ditto 2 6 



Length of the duodenum „ 1 3 



Circumference of ditto 4 



Length of the small intestines, inclusive of the 



duodenum 22 6 



Length of the cceca 1 3 



Circumference of the cceca and the small intes- 

 tines 2 6 



Length of the large intestines 6 



Circumference of ditto 2 9 



" The total length of the individual examined, measured over the 

 back, was 3 feet 2 inches and 6 lines; the length of the neck, 11 

 inches and 9 lines ; that of the trunk, 1 foot 1 inch and 9 lines." 



The reading of Mr. Reid's communication was illustrated by the 

 exhibition of the skeleton of the specimen of the Patagonian Penguin 

 described by him, and of preparations of many of the viscera, the 

 whole forming part of the collection of Mr. Blackett.

 HENRY ROSE.* 



AN emission of light has often been noticed during crystallization, 

 but its appearance has always been a casual one, and never, as far 

 as I am aware of, has it been produced at will. I have observed during
