292 HAY ASTHMA. 



ever, that numbers of these cases are not cases of Broken 

 "Wind, but probably some form of the malady now treated 

 upon. 



Symptoms pertaining to the state in question have been 

 known to appear in the horse as early even as five or six days 

 after turning the animal to grass ; so that the suddenness of 

 the attack, where it may happen, would of itself indicate the 

 disease as not being Broken Wind. 



Pathognomoi^ic Peoofs. — At present I am not aware of 

 any particular symptoms which characterise the disease as 

 being Hay Asthma and no other. It is rather to be judged of 

 by inference. Is the animal young ? Can the malady he attri- 

 buted to had hay, or to hay containing an ahundance of the grass 

 AntJiox Odoratum? 



TREATiiETfT. — The bcst remedies in general are — Bella- 

 donna,* Arsenicum, Lobelia Inflata, and Chloroform. 



Belladonna and Aesenicum. — These are remedies of 

 great value in Hay Asthma. I have tested them repeatedly, 

 and generally with good effect. Arsenicum, however, is not 

 applicable to so many forms of the disease as Belladonna. It 

 is not indicated in this disease, unless a discharge exists from 

 the nostrils ; when the nostrils are dry, the remedy will not 

 prove of the least value. Use it in 2-drachm doses of the 3rd 

 dilution, mixed with 2 ounces of water. Use the Belladonna 

 in scruple or half- drachm doses of the extract, which may be 

 mixed with powdered gentian and palm oil, and given to the 

 animal as a ball. These remedies should be given night and 

 morning, in alternation. 



* I would recommend a trial of Atropine (the active principle of Belladonna) 

 in these cases. Use it in scruple doses of the 2nd trituration.
