Sin: In conjunction with several other members
Of the Medical profession gave you, somo years
since, certificate Of the good quality of your
Mineral Water. With "a commendable jealousy Of
your own works. lest confidence in their abiding
good reputation should havo led to neglect you have
again applied to me for an analysis of several spec-
mems Of Mineral Water, purporting TO have been
made after different methods or BY different persons
the particulars Of which not furnished, the only
distinction apparent being in the color Of The bottles
l have examined the several specimens submitted,
md find as follows: The water in tho ,ohite glass
bottles is free from all impurities that in the green
bottles contains sensible quantity Of suphurc acid,
which is evident to tho smell and taste, well to
the proper chemical tests. From recent inspec-
ton OF your process was led to the conviction that
the only impurities which could possibly gain access
TO the water were lead and sulphuric acid. Ofleal
find no traces whatever in any Of the bottles; the
amount Of snphurc acid present Ia the green bottles,
though small, is objectionable and must be regarded
Us an mpu,ty as the Mineral Water processes to be
free from all such almixtures therefore certify
that the Mineral Water contained in the white bot.
ties sent to mo was pure, and in my opinion sauta
~, while that in the green bottles was impure and
unfit for q common beverage.
