ALOPECIA. 777 



such is always of so much vahie. Here they may, when ex- 

 amined, occasionally exhibit a slight change at their root 

 portions, being somewhat compressed and Avasted; as often, 

 however, they are unaltered, and throughout their entire ex- 

 tent exhibit none of the brittleness so commonly seen when 

 they are the subjects of parasitic invasion. 



In anatomical characters the true skin-structures appear 

 unchanged, and if the hair- follicles and glands are somewhat 

 atrophied it is all that can be detected. 



Treatment. — As already said, all cases of partial or very 

 extensive baldness have a natural tendency to return to 

 normal conditions ; but all seem to be assisted in attaining 

 this by attention to the principles of hygiene. 



When any weakness is apprehended, general tonics, as iron 

 with gentian or nux vomica, and linseed oil given in the food, 

 seem to benefit much. While of local means none are more 

 successful than regularly applied stimulation to the skin 

 through the medium of weak cantharides lotions or camphor 

 mixture. Should the skin become coated or in any measure 

 hardened by the use of these, it ought to be washed with soap 

 and water, and a little glycerine and water applied after- 

 wards. 



Class V. Hemorrhages. 



Cutaneous hasmorrhage, although a rare condition in the 

 horse, is still, from the possibility of its occurrence, deserving 

 of notice. Whether as symptomatic of certain diseased con- 

 ditions, or resulting from mechanical violence, the seat of the 

 blood-effusion is the same, the superficial vascular layer of the 

 true skin. In certain fevers, chiefly specific, attended with 

 hffimal changes, we may observe at particular stages of the 

 disease petechi.^ or ecchymoses. And probably these would 

 more frequently attract our notice, if observation were not 

 obscured by the hairy covering of our patients. When occur- 

 ring in the horse, htemorrhagic spots are rarely so rapid of 

 development as in man, neither do they comport themselves 

 in the same manner as in him. The term of their duration 

 does not, as with him, seem to depend on the extent and 

 depth of the haemorrhage so much as on the progress, favour-
