LENGTH OF THE INTESTINAL CANAL. 71 



en une verite d'observation ce qui n'est encore qu'une 

 presomption extremement vraisemblable." 



St.-Hilaire's suggestion appears never to have been 

 acted upon. There is no record, so far as I am aware, 

 of any measurement having been made of the intes- 

 tines of the African Cats, wild or domestic. With 

 the hope of being able to settle this question, at 

 the suggestion of Dr. P. L. Sclater, Mr. J. C. Mitchell, 

 Professor of Zoology in the College of Agriculture 

 at Gizeh, near Cairo, was applied to, and he has most 

 kindly sent the following measurements of the intes- 

 tinal canal of Felis chaus and the Egyptian Domestic 

 Cat ; he was not able to procure an example of the Felis 

 maniculata in the flesh *. The Egyptian Domestic 

 Cat has been much crossed with imported Domestic 

 Cats of different kinds, but that which he examined 

 he considered to be one of the pure breed.
