It is shown by these experiments, that when sulphate of atropia is adminis- 

 tered five minutes after this dose of physostigma, successful antagonism is 

 produced by any dose of sulphate of atropia ranging from one twentieth of a 

 grain to two grains and one tenth. In Experiment 198-a., successful antag- 

 onism likewise followed the administration of two grains and one fifth of 

 sulphate of atropia ; but as this result was not obtained in the next experi- 

 ment, in which the same dose was given, I have not included it within the 

 limits of success. 



Experiments with Twice the Minimum- Lethal Dose of Physostigma. — The 

 following results were obtained when atropia was administered five minutes 

 after a dose of physostigma twice as large as the minimum-lethal : — *
