Emetics. 



Vomiting appears almost a natural act in dog's ; at least it 

 is one that they voluntarily excite, by eating emetic vegeta- 

 bles, as the long wild grass, so hurtful to pastures. Dogs, in 

 common with all quadrupeds who eat animal matter, are 

 subject to irregular digestion and a train of sensations that 

 we denominate bilious. In the canine species these are par- 

 ticularly prevalent ; and dogs appear to be instinctively taught 

 to relieve themselves from them by an emetic, which they 

 take more frequently, when they can procure it, than we are 

 aware of. It is evident, therefore, that such as are much 

 confined, and those who inhabit large cities, must suffer in 

 their health from the want of this usual evacuation. To re- 

 medy this, when circumstances wholly prevent their reaching 

 the grass, or other emetic vegetables, some of the dog grass 

 might be brought to them, either gathered, or the roots of 

 it might be placed in pots for their use. It may be obtained 

 by the Londoners in Covent Garden. In default of this, a 

 mild occasional vomit, or tartarised antimony, emetic tartar, 

 common salt, or other emetic substance, may be very pro- 

 perly substituted, and which I have frequently recommended, 

 to the great benefit of the animals who have used them. 



In various diseases, the benefit resulting from the use of 

 emetics is still more striking ; and, throughout the work, di- 

 rections for their employment will be found frequent. A
