sufferer must have eaten Amanita pantherina. He states that 

 poisoning by Amanita muscaria results in lOO per cent, recovery. 



The symptoms from this class of poisoning develop within one 

 hour. Recovery may require a day or a week. 



Conclusions. — The poison is not destroyed by heat but it is 

 soluble in hot water after five minutes' boiling. As I mentioned 

 before the southern negroes may possibly be able to prepare this 

 Amanita muscaria in a way which renders it edible. 



The hot water boiling five minutes dissolves out the muscarine 

 and neutralizes the acrid resinoid. Washing in salt and water 

 removes the phalline and perhaps the pilz-atropin and if this 

 does not, then steeping in vinegar removes any residual part of 

 the poisons. As the poisons are not destroyed, only dissolved 

 out of the mushroom, we must throw away all the water and 

 vinegar used in preparing them. 



Method of Preparation. — This method of preparing mushrooms 

 should be used in all cases where there is any doubt about the 

 edibility of the variety to be tried. But we must remember that 

 there are poisonous mushrooms which never give up their poison 

 by this method, namely, Amanita phalloides, Amanita spreta, 

 Amanita solitaria, Amanitopsis volvata and stale Gyromitra escu- 

 lenta. For all forms except these we may consider this method of 

 preparation one which will remove or neutralize the poison. 



This preparation is as follows:
