contamination. After some correspondence it was 

 agreed, between the County Council and the 

 Council of the Royal Society, to enter upon an 

 investigation, the expense of which was to be 

 defrayed partly by the London County Council 

 and partly by the Royal Society out of the 

 Government Grant for Scientific Research. When 

 we consider how much of disease and death is due 

 to contaminated water, we must feel that it is 

 scarcely possible to overestimate the vital import- 

 ance of the proposed investigation. Let us hope 

 that the alliance between the London County 

 Council and the Royal Society, for this great 

 work, may be successful in bringing out practically 

 useful results.
