THE ORIGIN OF LIFE 



tory, Cambridge, made a first announcement of 

 some experiments which he has been conducting 

 for some years back. He has demonstrated the 

 development, in sterilized bouillon subjected to the 

 action of sterilized radium chloride or bromide, of 

 minute bodies which exhibit growth and sub- 

 division. The American reader will find an ac- 

 count of this work in an article contributed by me 

 to Harper's Weekly for July 22, 1905. I make no 

 detailed reference to it here, though I have had 

 the opportunity of studying Mr. Burke 's results for 

 myself, since he is about to publish a volume on 

 the subject, and since the nature, origin, destiny, 

 and distribution of life must engage me for a sub- 

 sequent volume.
