which usually takes two or three applications. It may

Emetics. — Emetics are sometimes required for the 

 dog, though not so often as is commonly supposed. 

 Vomiting is a natural process in that animal, and seldom 

 wants provoking; indeed, if emetics are often had re- 

 course to, his stomach becomes so irritable that neither 

 medicine nor food will remain on it. Hence their 

 administration should be carefully kept within the bounds 

 of absolute necessity. 



Under proper regulations emetics have a useful place 

 in canine medicine. They greatly assist other remedies 

 or measures by the facility with which they cause 

 rejection of the contents of the stomach, and produce 

 a direct sedative effect on the system, which proves 

 beneficial in active diseases as pneumonia, hepatitis, 

 enteritis, &c. 



Prescriptions. — i. Tartar emetic, | to i gr. ; powdered 

 ipecacuanha, 4 to 5 grs. Mix, and dissolve in a little 

 water, to be given as a drench, and to be followed by 

 2 to 8 oz., of lukewarm water, in a quarter of an hour. 



2. Coi7i77ion Salt Emetic. — A teaspoonful of salt and 

 half this quantity of mustard are to be dissolved in half 

 a pint of warm water, and given as a drench. 



Expectorants. — Remedies of this class are employed 

 to assist or relieve the lungs by promoting discharge 

 from the mucous lining of the air passages, in which office 

 they prove eminently useful. They restrain irritation 

 and thus remove the cough which it occasions, promote 

 tranquillity, affording rest and comfort to jaded spirits, 

 and greatly facilitate recovery. 



I. Bolus. — Carbonate of ammonia, finely powdered, 

 I drm. ; gum asafoetida, i drm. ; extract of belladonna, 

 12 grains. Pulverise the ammonia and gum separately, 

 using to the latter a few drops of spirit of wine, then 

 mix and triturate together, finally rubbing in the extract 

 with linseed meal and treacle to form a paste. Divide 

 into 12, 18, or 24 pills according to the size of the 

 patient.
