 to the size of the stable. 



Take of common salt, eight ounces. 

 Manganese, powdered, six ounces. 

 Let these be well mixed and placed in an 

 earthen dish, then pour on the mixture gra- 

 dually, of vitriolic acid, four ounces. As 

 soon as the latter is added, the operator 

 should leave the stable, shutting both the 

 door and the windows. The fumes which 

 arise from this mixture are highly injurious 

 to the lungs, and must be carefully avoided ; 

 tlierefore this fionigation can only be per- 

 formed in an empty stable. During the 

 whole day, the stable door and windows are 

 to be kept shut; but at riight they may be 

 thrown open, that there may be no danger

 the fumigations, Jiaving found that ^^hell 

 glanderous matter is exposed to it a short 

 time, it is rendered perfectly harmless. 

 The fumes which are generated by pouring 

 oil of vitriol, or vitriolic acid, on po vdered 

 nitre, are said to be very effectual in di.siroy- 

 ing human contagion; how far it may be 

 serviceable in veterinary practice, remains
