ferments, or leavens, when introduced into the circulation. 

 Professor PoUi, of Milan, has clearly demonstrated that 

 this substance is capable of purifying the blood of noxious 

 matters, and further, he has by his experiments upon dogs, 

 proved that glanders can be cured by it; for he says, that 

 forty-five grains of the virus of glanders taken from the 

 nares of the nose of a glandered horse, and injected into 

 the circulation of a dog, after the disease had shown itself 

 in the dog, Avas readily cured by the administration of the 

 sulphite of soda. Upwards of seventy cases have thus 

 been experimented upon by this distinguished professor — 

 all going to show the value of soda, as a purifier of the 

 blood, by its alterative efl^ects. 



Sulphite of soda is a remedy in all cases of eruptions on 

 the skin, in farcy, glanders and purpura in the horse, and in 

 pleuro-pneumonia and rinderpest, etc., in cattle. Wherever 

 pus is thrown out as a product of disease, the sulphite of 

 soda should be given. Dogs with distemper should have 

 it to keep the circulation pure of pus. The blood of the 

 dog becomes contaminated in this way, and hence, the good 

 doj^ falls a victim to this scourge of fine bred animals. 



Dose. For horses and cattle, the dose is from half an 

 ounce, to one ounce, given twice in the day. For dogs, 

 twenty grains given in camphor water. In farcy and 

 glanders or other diseases, accompanied with debility, the 

 soda should be combined with gentian and other tonics. 



Spanish. Fly. — Lytta Cantharides. An insect ground 

 into powder, and mixed with lard or oil, making what is 

 familiarly known as a blister. The Spanish fly is, besides 

 its blistering qualities, a very valuable internal medicine, 

 a powerful tonic and alterative, and has been used with 

 success, in the hands of Mr, Vines, of London, England,
