242 THE CONTAGIOUS TYPHUS 



beverage. If he is confined to the stall we will 

 give him the open air, and let him graze the 

 fields ; which is a treatment by itself for the 

 invalid animal, so vivifying is the pure air of 

 the common, and so thoroughly different from 

 the atmosphere which is pent up within his 

 stall. If the animal is strong, lusty, exu- 

 berant with health, let him be purged once or 

 twice, the purgative to be given at intervals 

 of twenty-four hours. (We shall give the 

 medical formula in the chapter addressed to 

 farmers, graziers, &c.) 



This purgation, moreover, will correspond 

 with the theory of those authors who consider 

 the evacuations as the proper means of deli- 

 vering the economy from the infectious miasms 

 which have been absorbed. 



If the beast is plethoric, recourse should 

 sometimes be had to bleeding, especially in hot 

 and dry seasons, like the one we have recently 

 passed through. 



These stimulative and depletive medications 

 cannot but be favourable to the animal, since 

 it will anticipate the treatment to which he 

 must be submitted a few days later, when the 

 disease shall have declared itself.
