SCABIES. 103 



Creasote 5!., spts. vini recti "^xv., aqua ^xl. ; or creasote 

 li., aqua 5XX. The former is, however, the best formula. 

 It may also be used in equine practice. Another good 

 application is, tobacco 5i., aquse O.l ; make an infusion. 

 This is also excellent for the destruction of ticks, etc 

 White hellebore 3i. may also be added to the above if 

 desired, making a very powerful and effectual application' 

 Uugt. hydrarg. is also of considerable efficacy, and highly 

 thought of by some. Prophylactic measures consist in 

 keeping the pens and stabling clean, fumigating, etc. ; also 

 keep healthy animals off infected pastures. 



Ringworm. — This is another affection caused by a parasite 

 belonging to the cryptogama, i.e., derived from the vegetable 

 kingdom. It is called ringworm on account of the pecu- 

 liar manner of its arrangement. The parasite is a species of 

 fungus, of minute size, and the disorder is undoubtedly 

 contagious. It attacks all animals, horses in good condition 

 appearing to be fully as susceptible as horses in poor con- 

 dition. The vitality of the parasite is very great, and in 

 many cases it has been known to live for upwards of six 

 months. Eingworm is communicable from one animal to 

 another, and from animals to man. 



Sf/mj)toms. — Small pimples appear on various parts of the 

 body, usually about the head, neck, and loins. After a short 

 time the hair begins to fall out, in many cases coming off in 

 circular patches; and now, by using the glass, little elevations 

 or ridges are discernible, the ridges, of course, being due to 

 the attack of the parasite. The affection, unless checked, 

 soon spreads over the whole of the body. There is a slight 

 oozing out of fluid from the affected parts. In some cases the 

 affection may be circumscribed in character, attacking and 

 remaining confined to one part only. More particularly is 

 this the case in the horse, in which animal it is easy to treat. 

 In man, however, its cure is a matter of some difficulty.
