Electi^otonic decreme7it first described by Bernstein in du Bois- 

 Reymond's Archiv., 1866, p. 614. 



Polarisation increment first described by Hermann in Pfluger's 

 Archiv., vol. vi., p. 560, 1872; and further explained in

[Previously noticed by Griinhagen, but by him 

 attributed to a diminution of resistance. (Zeitschrift 

 fiir rationelle Medicin, 1869.)] 



Experiments illustrating the action of anaesthetic and other 

 reagents on electrotonic decrements and polarisation incre- 

 ments are given in the Croonian Lecture for 1896. (Phil. 

 Trans. R.S., 1897).
