It is evident that the injection of water and of Ringer's fluid, as 

 well as that of the lo per cent alcohol, was followed by an increase 

 of work done. The experiments are not sufficiently numerous to 

 justify final conclusions as to the relative influence of the alcohol as 

 against the water, or Ringer's fluid ; but it is significant that the per- 

 centage of increase is less after the injections of alcohol than after the 

 injections of the other fluids. Thus while 12 out of 13 alcohol experi- 

 ments gave less than 40 per cent of increase, 5 of 13 with water and 

 Ringer's fluid gave more than 40 per cent. Moreover, the increase 

 in six of the alcohol experiments was less than 20 per cent, while in
