Amherst Mineral Spring is situated at Ambers t, Hillsboro County, 

 N. H., and is owned and operated by Messrs. Geo. C. & E. A. Boutell, 

 of Pittsfield, Mass. The spring was visited in November, 1907, 

 samples directly from source being obtained for tbe examination. 

 Chemical analysis shows this to be a calcic, sodic, ferruginous, 

 bicarbonated water of the alkaline type. Approximately 55 per cent 

 of the salts in solution are in the form of bicarbonates of lime, mag- 

 nesia, and iron, with a small amount of the sulphate of magnesia and 

 the sulphate and chlorid of soda. The sanitary analysis shows small 

 quantities of free and albuminoid ammonia, with traces of nitrites 

 and nitrates. Inspection of the premises failed to reveal any prob- 

 able source of pollution. The advertised analysis differs very materi- 

 ally from the analysis made by this bureau. 



1 At C. and 760 mm pressure in 1,000 cc of water. * No bacteriological sample taken.
