These two analyses were made at different times by two 

 different London Analysts both doing a large practice. Pro- 

 bably the first most nearly represents the water derived from 

 Dowdeswell Reservoir, being the head water of the River Chelt ; 

 the latter that derived from Hewlett's Reservoir being spring 

 water from the base of the Inferior Oolite. 



The following is a mineral analysis of water from a well in the sand bed situated 

 in the middle of the town.
