296 CURSORES. 



tines are as in the hen. The testes were black, and there are two 

 penises, as in a cock. 



The Partridge [Perdix cinerea, Ray]. 



A partridge has a crop : the viscera are just like a fowl's. The 

 rectum is about 5 inches long; and the caeca each 4 inches. The 

 length of the whole intestine was one length and a half of the bird. 

 The ovaria were white. Its flesh was very red, and it has bones for 

 tendons in the legs. The testicles are black. The redness of the 

 cheeks is owing to the colour of the rete mucosum ; for, by steeping the 

 chin in water until the cuticle comes off, it is found like a red paint 

 between it and the cutis. 



Norway partridges feed in the winter upon the buds of trees or shrubs, 

 and the small stalks on which these buds stand.

The Ostrich \_Struthio camelus, Linn.]. 



The ostrich is very weak everywhere, excepting in his legs. As the 

 anterior parts of the body are of no use, excepting what immediately 

 concerns the economy of the animal, it is there extremely weak ; but 

 as the legs are its support, also its offensive and defensive weapons, and 

 as its whole progressive motion is by walking or running, everything 

 relating to them is strong. 



The gait of this bird resembles that of the camel very much : the 

 motions of the head are very like also ; but that may be owing to the 

 ength of the neck in each : their lying down is also much alike ; for 

 both he down on their breast, so that there is a hard part on the breast 

 of each, whose fat is like that upon the sole of the foot in men. The 

 ostrich has another pad on the pubis (which bones are united together 

 in the ostrich 1 ), so that he rests upon two points, viz. the breast and 

 pubis, with his two legs laterally folded parallel to the body, so as to 

 rest upon the whole tarsus. 



The feathers are rot so firm as in most other birds, nor so close-set 

 upon one another. The lateral plumes are very soft, long, and not at 

 all close ; something like those of a peacock's tail 2 . The skin on the 

 sole of the foot is studded with horny processes, about a | of an inch 

 long, thicker than four or five bristles, parallel to one another, and 

 very thickly set ; so that the ends of them seem to make a rough sur-
