 who took about one half an ounce of a soluble oil of wormseed. Dr. Mills- 

 paugh says that the symptoms were those from a narcotic, acrid poison, af- 

 fecting the brain, spinal cord and stomach. The patient was insensible, con- 

 vulsed and foamed at the mouth. In another case a man who had taken a con-
