CONTAGION. 299 



739. — Boil two ounces of quassia chips, in two quarts of 

 water, for half an hour. Strain off the chips and put half an ounce 

 of salt in the liquid. When blood warm gently inject into the 

 rectum. If retained half an hour or more it will give great 

 relief, but if expelled immediately try again next day. 



740. — This simple remedy may be repeated whenever the 

 worms are seen to be troublesome, and will never do any harm. 

 But don't pour in the salt without weighing or measuring it. 

 Physic will injure the horse without injuring the worms. 



MANGE. 



741. — If the short hairs at the root of the mane come out 

 easily, and the horse stretches out his neck, tosses his head, and 

 exhibits a desire to increase the friction of your fingers when you 

 touch his mane, it will be a case of mange. In that case you 

 have not an obstinate, but a very contagious disease to deal with, 

 and one that will have been communicated to every horse that 

 the diseased horse has touched, that has rubbed against the same 

 stalls or posts, used the same clothes or harness, or been cleaned 

 with the same combs or brushes. 



742. — It is not difficult to cure ; you have simply to destroy 

 an insect that is burrowing and breeding iu the horse's skin. 

 The insect is called the acarus, and buries itself in the horse's 

 skin just as a smaller insect will do in the neglected skin of man, 

 producing the itch ; or in the skin of the sheep, producing the 

 scab. 



743. — The skin may be washed all over with sulphur, 

 dissolved in boiling lime water, and used warm. The sulphur 

 will not dissolve in water without lime. Little's Chemical Fluid,' 

 or any of the good sheep dips, or preparations of carbolic acid, 

 or glycerine may be used in the same way, and where they can be 

 got, are more pleasant in their action on the skin. As the insects 

 or their eggs are completely protected under the skin at certain 

 stages of their development, no one washing will destroy them all. 

 To ensure a cure it will be necesary to repeat the application 

 every third day for a fortnight. At the same time every thing 

 that the horse could have touched whilst the insects were alive
