theine, becomes strongly contracted, but it is uncertain whether — 
this effect is produced by coagulation of the myosin or not. 
In muscles which had been soaked in curare until the nerves 
were killed the same rigidity was produced. 
In comparing the physiological effects of theine and caffeine

that the former does not affect the elimination of carbonic.
