288 COUGH. — CHEONIC COUGH. 



other medicines could be enumerated ; but as it might only tend 

 to confuse the reader with regard to the proper choice of a 

 drug for any particular case, I forbear to name others. I have 

 found Belladonna to be the best remedy for the general run of 

 coughs, but the quantity necessary to use for a dose yaries in a 

 singular manner. Numbers of horses require the extract of 

 the drug in half-drachm doses, and the dose repeating daily for 

 several days in succession, before its effects upon the cough are 

 satisfactory ; while to others, 2-drachm doses of the 3rd dilu- 

 tion will remove the violence of the cough, when the extract 

 may have failed to produce the least apparent good. 



BETOisriA 1. — Bryonia is frequently valuable, if given to 

 coughs of recent origin. Use it of the 1st, and sometimes of 

 the 3rd dilutions ; and give the remedy in 2-drachm doses 

 of the 3rd dilution, at least once a day. 



Setons. — Sometimes the passing of a Seton, ten or twelve 

 inches in length, between the outer surface of the windpipe 

 and the inner surface of the skin, in the direction of the long 

 axis of the former, and allowing it to remain for two or three 

 weeks, will prove of signal service. 



Diluent Deinks, composed of linseed tea, honey and 

 Spanish juice dissolved and mixed together, will frequently 

 benefit the patient in these cases. 



HAY ASTHMA. 

 I have given to the present disease the name of " Hay 

 Asthma" — not because it holds any very intimate relation to 

 the malady known as Hay Asthma, which affects the human 

 being, but because in the horse it originates in the animal par- 

 taking of a peculiar kind of dried grass amongst the fodder 

 which may partly constitute its diet.
