CANINE ASTHMA. 131 



should happen, discontinue the medicine for some days. Where 

 also the calomel has been found to disagree, I have substituted the 

 following alterative with benefit : — 



Nitre (nitrate of potash) 3 grains 



Tartar emetic (tartarized antimony) . . a quarter or half of a grain 

 Powdered foxglove (digitalis) half or a whole grain. — Mix. 



This may be given as the other, and alternated with the emetic 

 also, watching the effects of the foxglove, through the medium of 

 the pulse, that they may not be too violent. 



In some cases of long standing, where the attendant cough has 

 been very harsh, noisy, and distressing, I have added ten, twenty, 

 or thirty drops of tincture of opium (laudanurn), or the eighth, 

 sixth, or the fourth part of a grain of opium, to each alterative 

 with advantage. In other instances the cough has been best 

 allayed by an evening opiate of double the strength before pre- 

 scribed. I have, now and then, experienced benefit also from the 

 use of the balsamic gums, which may be all tried, therefore, in ob- 

 stinate cases. Thus relief has been obtained from the following, 

 given every morning : — 



Powdered squill a whole or half a grain 



Gum ammoniacum, powdered 5 grains 



Balsam Peru 3 grains 



Benzoic acid 1 grain 



Anisated balsam of sulphur to form a ball. 

 Or, 



Inspissated juice of the white garden lettuce . . half a drachm 



Tincture or balsam of Tolu 1 drachm 



Powdered gum arable and extract of liquorice 1 ounce each 

 Make into balls, and give one night and morning. 



I have also found the underwritten to mitigate the severity of 

 several cases, and it deserves a trial : — 



Extract of cicuta half a drachm 



Extract of hyoscyamus 10 grains 



Powdered digitalis a scruple 



Conserve of roses to make 10, 8, or € balls, according to the size 

 of the dog ;
