SYMPTOMS. — ^Violent and continued spasms, which cause death 

 by stopping the breathing.

 pint of water, as a drench; or J oz. of it dissolved in 2 oz. of

 inhale chloroform. If these drugs cannot be obtained, give large 

 doses of spirits (a couple of quarts of whisky or brandy) and 

 water.
