4. Apparatus Used. 

 In these observations I have used : — 



(1) An early model by Edelmann of Einthoven's galvanometer with a 

 platinum fibre of 2000 ohms resistance, and platinum electrodes dipping in 

 normal saline. 



(2) An oscillograph (Bock-Thoma model) by Thoma, of Munich, with a 

 condenser of large capacity (10 and 20 mf.) in circuit, and, as before, platinum 

 electrodes in saline. 



Each of these instruments possesses advantages and disadvantages ; for 

 the special purposes of the present observations the second instrument has 

 proved to be the more convenient. By the use of platinum electrodes
