The nerve is irresponsive after 46 minutes. 
Exp. 36. Liquid: 3 ce. 2°/, lecithin and 2 ce. Ringer (1.8°/, Wen 
1 ce. cocain solution 5°/, is equal to 0.83°/, cocain hydrochloricum 
in a 1°/, lecithin solution. 
Result: After 62 minutes the nerve is still responsive. 
From experiments 35 and 36 it appears then that 50 mers of 
lecithin can inhibit the action of 50 mgrms of cocain considerably. 
Zep. 37. Here we examined the influence of an ether extract of 
dried cats brains. Of itself this extract is indifferent to the nerve, 
which after 60 minutes is still normally responsive.
