4. Strength of stimulus. 



I have not succeeded in exercising an influence on one of the 

 two parts of the veratrinogram separately by means of the strength 

 of the stimulus. If the strength of the stimulus is gradually diminished, 

 we may observe as Mostinsky ') describes, the critical progress of 

 the excitability of the veratrin-muscle, i.e. below a definite limit, 

 which is very exact, no reaction occurs on irritation, above this 

 limit a reaction, differing but little from the maximal; moreover 

 this always is a complete veratrinogram.

 will appear in the ,, Archives de Physiologie Nêerl.""
