We have made these investigations from a purely biological 
point of view. When one begins an investigation of this

gone over ground which has been already traversed by 
brewers’ chemists: it would be surprising if it had not been.

propose to take up some other aspects of the question in other 
series of experiments.

In imagination the lecturer and his audience journeyed in
