These precautions are necessary 



It is not known to many that' hen lice and com,mon human 

 body lice grow on horses with great rapidity. Hen lice especially 

 are sometimes very troublesome. Prof. Bouley, in 1851, first called 

 attention to them. - , /

Symptoms. — When a horse is taken suddenly with irresist- 

 ible itching, sometimes acting, half frantic in his efforts to relieve 

 himself by scratching, biting, striking up with his hind feet, and 

 stamping, examine him carefully for hen lice. This trouble is to be 

 particularly looked for where hens have access to, or roost in, the 

 stable. There is liable to be an eruption of very small vesicles under 

 the 1 skin, the hair falling off in small, circular spots. In a few days 

 these spots are liable to extend. \ 



' When neglected, or not attended to, 

 the horse is liable to lose his appetite, 

 grow thin and weak, on account of the 

 constant annoyance arid irritation to 

 which he is made subject. 



Treatment. — Remove the cause. Hens 

 should never be kept near a horse 

 stable, nor allowed to roost in it. Wash 

 the animal with a decoction of tobacco 

 or stiaphysgia ; whitewash the stable, 

 and observe cleanliness. If subject to 

 human lice, and the animal is poor, 

 with long hair, clip it off, and wash the 

 , animal with a decoction of stavesacre, 

 one ounce of the powdered seeds to a pint of water, taking care 

 that the animal does not lick himself for some time after the remedy 

 has been applied. — Williams.
