It need hardly be stated that my experiments add Httle essen- 

 tially new to those of Wilson; yet they seem to afford valuable 

 confirmation of some importance which may add to the con- 

 clusiveness of his admirably conceived and conducted research. 



I desire also to express my gratification in the experiments of 



DeMorgan and Drew, which seem to me to have been admirably 



done and contribute to the value of the investigation as a whole.
