 young. In case the mass of false membranes is coughed up a 

 recovery may be hoped for. The absence of additional croupous

Treatm,ent is usually unsatisfactory. The hot, moist jacket, 

 inhalations of vapors or warm water, of carbonate of ammonia, 

 and of ether may be tried, counter-irritants to the chest, and in- 

 ternally, liquor ammonia acetatis and iodide of sodium would be 

 indicated. When the membranes are somewhat loosened pilo- 

 carpin, or in weaker subjects apomorphine may assist their ex- 

 pulsion. Peroxide of hydrogen may be injected into the trachea 

 with due caution against sudden asphyxia.
