TRIMETHYLAMIN 



tension of a finger is at first obstructed, but finally 

 accomplished with a jerk or sweep. T.-material, an 

 apheter ; any theoretic catastatic substance whose sudden 

 breaking up communicates an explosive decomposition 

 to the protoplasm directly concerned in any function. 

 The trigger-material itself must be acted upon by an- 

 other trigger-material ; and thus every nerve-impulse 

 and every functional act must be accompanied by the 

 destruction of a fuse-like train of protoplasm. See 

 Apheter.
