This is given by ignorant men for purposes which are defeated; but, being an acrid, irritant poison, it produces serious results, frequently causing inflammation of the urinary organs.

Symptoms: Violent thirst, copious discharge of bloody mucous from the stomach, mixed with which may be seen the shiny green particles of the "flies;" there are great pains in the loins and bowels, swelling and inflammation of the genital organs, and bloody stools and urine.

Antidotes: An emetic should at once be resorted to, the dog should afterwards be drenched with demulcents, and a dose of opium given every three or four hours.
