If one writes (6) in tlie form of (3) one sees immediately tliat the 



rheobase of La Picque ( here represented bv j represents the 



value of P for very great value of C, whilst the chronaxie of 

 La Picque is nothing else than the reverse of my coefTicient /?. 



It may be mentioned here that at the international Congress for 

 electrology, held in 1910 at Barcelona, it has been resohed to apply 

 my condensator-method for the examination of the sensibility of nerves 

 and muscles, and to adopt the coefficients « and ji as the common 

 measure for that sensibility. The Spanish Government has then pro- 

 mised a premium of frs 1000 for the best set of instruments required 

 for those experiments. 



3. For the effect of irritation by con.stant cui-rents of «hort duration 

 the formula (5) furnishes: 



a 

 J = (7) 



a formula afterwards found independently by La Picque (11) and 

 corresponding better with the experiments for constant currents of 

 short duration than the formula (4). 



Not only for these two cases, but also for all other manners 

 of electric irritation, the formula (5) furnishes good results, as I have 

 shown once more in details in Teijlers Archiv (2). It explains like- 

 wise very easily the so-called "Einschleichen" of a strong constant 

 current, and, as this phenomenon offers great difficulties with other 

 theories, I shall here repeat my explanation once more (13). 



Axis of time. 



Be ABCD the graphical representation of a galvanic current, 

 that is shut in the time AE, remains constant during the time EF" 

 and is then broken off at C. This current, conducted into a sensible
