Physiological Action. — Liquor ammonise if 

 used locally causes considerable irritation, abstracts 

 water from the tissues, dissolves the epithelial 

 scales, liquefies their albumin, and saponifies their 

 fats — therefore acting as a caustic. Full doses given 

 internally stimulate the spinal cord, motor nerves, 

 and muscles, are said to produce tetanic convul- 

 sions, and finally paralyze the cord. Suffocation may 

 be brought about by large quantities of the gas en-
