 General Treatment of Inflammation in Bone. Unless in 

 the very mildest cases, the first object is to check the in- 

 flammation by soothing measures. A purgative is usually 

 desirable. Rest is indispensable. Whenever possible 

 such a position should be given to the part as will obviate 

 pressure, weight, or gravitation of blood toward the dis- 

 ease. Soothing local measures, such as fomentations with 

 warm water ; a thick wet bandage covered with dry ; the 

 persistent apphcation of cold water, by continiious shower- 

 ing of the part, the water being brought from a bucket 

 placed at a higher level, by means of an elastic tube 

 fastened to the body ; in certain cases ice-bags may be 

 apphed ; or cooling astringent lotions, such asTinegar and 

 salt ; acetate of lead ^ oz., vinegar 2 qts., carbolic acid 60 

 drops, etc. This may have to be kept up from five to fif- 

 teen days. When heat and tenderness have subsided, 

 counter-irritants are to be used. In sHght cases rubbing 

 with compound iodine ointment, or with a mixture in equal 

 parts of liquor ammonia and olive-oil may suflice. In 

 others we must use active blisters such as Spanish flies 

 2 dr., camphor 5 grs., alcohol 5 drops, lard 1 oz. Or a 

 drachm of the Spanish flies may be replaced by a drachm 

 of iodide or biniodide of mercury. In either case the hair 

 should be cut off and the ointment well rubbed in for 

 several minutes against the direction of the hair. The 

 animal's head should be tied short for twelve hours, to 

 prevent gnawing of the part and blistering of the hps. 

 After this the surface is to be smeared with lard, daily, 

 until the scab drops off. In still other cases the hot iron 

 may be demanded. It should be applied in points, each 

 application being very temporary, to avoid the effect of 

 radiated heat on the adjacent skin. The usual distance 

 between the points is from ^ to f inch, and the depth wil/
