Mercury. — A liquid metal called quicksilver. In its 

 metalic state it is not used as a medicine. There how- 

 ever is a prevalent idea in the minds of ignorant persons, 

 that doctors, and veterinary surgeons give this substance 

 to force a passage through the bowels, and that if it fails 

 the bowels and stomach will be ruptured, or torn. If 

 the patient should die, the blame is not unfrequently laid 

 on the use of quicksilver by the doctor, when this sub- 

 stance was never thought of for any such purpose. 

 Quicksilver has no action whatever on the animal sys- 

 tem, either in health or sickness.

 it one day. For this purpose, four grains of the subli- 

 mate to two ounces of rain water. For dog, two grains 

 to the ounce, in water, will be strong enough.
