FOKM OF THE HEAD 



39 



The former proposition is not accepted by all writers on this subject; 

 but without insisting too much upon it, it seems as reasonable an inference 

 to draw as that a large, deep chest betokens voluminous and capacious 

 lungs. There is no doubt, as pointed out by (roubaux and Barrier, that the 

 temporal muscles, which extend from above the eyes to the roots of the 

 ears and take such an active part in the function of mastication, add 

 somewhat to the transverse diameter of the forehead; but this does not 

 invalidate the argument that a broad forehead is an expression of a broad, 

 and consequently large, brain cavity. On the contrary, the presence of 

 large muscles is an indication of large bones; and since the bones to which 

 these particular muscles are attached form a considerable part of the vault 

 of the cranium, the logical inference is that the cavity of the latter, in 

 respect to size, stands in relation to them. As to whether the intel- 

 ligence in the horse is proportional to the width of the forehead, or in 

 relation to the volume of the brain, are questions into which we do not 

 propose to enter; but from the foregoing considerations we are in agree- 

 ment with Gayot that the more voluminous the brain the larger is the 



spinal cord and the 



nerves that proceed from 



it, and that "a large 



forehead denotes a high 



degree of intelligence 



and a good nervous sys- 



tern . 



From the forehead 



downward the face 



should still maintain 



ample width, to give 



room to the nasal pas- 

 sages wliich form its 



front and lower aspect. 



From the eyes, the la- 

 teral boundary lines in 



a well -formed face will 

 gradually narrow in towards the angles of the mouth and then widen 

 out in conformity with the nostrils, which should Ije open and capacious. 

 Moreover, the skin encircling the nostrils should l)e thin and pliable, and 

 the lips fine and mobile. The bony lines and prominences of the face 

 should be clearly defined, and not, as seen in the low-bred and phlegmatic 

 subjects, hidden by undue thickness and Heshiness of the skin and suli- 

 cutaneous tissue.
