THE HORSE IN SICKNESS AND DISEASE 271 



Next administer tonics. Of these, sulphate of copper, 

 sulphate of iron in his drink ; chloride of barium (muriate 

 of barytes), in half-ounce doses at first, increased to one 

 ounce daily, in a ball with meal and molasses, have each 

 their advocates. For ourselves, we advise the tonic to be 

 varied, upon experience of its efficacy or the reverse. 

 Blaine tells us that nearly all the mineral acids have been 

 found useful, and some of the vegetable ones, xill the 

 different forms of mercury have been tried with some 

 success ; but corrosive sublimate appears to have answered 

 best ; and when determined on, should be given to the full 

 extent the stomach and bowels will bear without salivation 

 or symptoms of inflammation being brought on. Ten or 

 fifteen grains may be commenced with, ground very finely 

 with sugar, and given night and morning in gruel as a 

 drench. 



If this occasion no distress, it may be increased to a 

 scruple, and from this to half a drachm, if it be borne 

 with ease ; but the utmost care and watchfulness should be 

 exerted when the dose is considerable. When the weakness 

 and irritability of the horse are too great for the exhibition 

 of the corrosive sublimate, give half a drachm of calomel 

 twice a day ; or the blue pill, or the sulphuret of mercury 

 may be substituted, still carefully watching the salivating 

 process. Should the stomach sutler much under the use of 

 these active agents, either join with them bitter tonics, or 

 alternate them with each other. We would also recommend 

 that they be in these cases given in solution, and further 

 sheathed by some ingredient of a mucilaginous nature. 



After the trial of mercurials, arsenic ought next to claim 

 the attention, as that has also proved efficacious in farcy ; 

 and it may be given in the form of liquor arsenicalis, or 

 Fowler's tasteless solution. Verdigris wa ifor some time a 

 favourite remedy at the Veterinary College, in doses of a 

 scruple three times a day, increased to a drachm. We have 

 witnessed also good effects from this preparation ; but we 

 have found it most efficacious when given in a ball in con- 

 junction with the blue vitriol, half a drachm at a dose. 

 Some practitioners choose to employ several articles in 

 conjunction, and they assert the cure is speedier from the 

 combination than from any one article separately. In this 

 case, give the following
