Elementary Anatomy of a Hound 55 



is principally maintained by " panting," which re- 

 presents a modified form of perspiration by the skin. 



The skin is composed of two portions, viz., an 

 upper one or epidermis, and a lower one, the corium, 

 or true skin, and it is in the last named that the blood- 

 vessels, nerves, sweat glands, etc., are situated. 



The superficial layers of the skin (cuticle) are con- 

 stantly being shed in scurf and replaced by division 

 of the cells situated in the deeper layers of it. 



The Eye 



A knowledge of the elementary anatomy of 

 the eye is of value to everyone, more especially 

 when one considers the vital importance of the eye- 

 sight, defects of which may render a dog such as 

 the Greyhound useless for work. 



Without the possession of the normal senses — 

 sight and smell, likewise that of hearing and taste — 

 a dog is handicapped, though to a variable degree, 

 in accordance with the specific lines it has to 

 undergo. 



Some hounds hunt by sense of smell only, others 

 by sight, whilst a third class work by the combined 

 use of both these senses. 



The range of vision would appear to be very ex- 

 tensive in the Greyhound, and the same remark 

 applies, in a modified sense, to the sight of the 

 whippet.
