Mr. Schmeisser's Analysis of 
EXPERIMENT VI. 
On adding a few drops, both of the aqueous and spirituous 
infusion of galls, to a glass of the fresh water, no change of 
colour took place ; yet by means of well saturated phlogisti- 
cated alkali some traces of iron were perceived. 
EXPERIMENT VII. 
A solution of soap in spirit of wine being dropped into the 
water, was immediately decomposed by it. This proves it to 
contain neutral salts. 
EXPERIMENT VIII. 
By adding some acid of sugar both to the fresh and the boiled 
Kilburn water, calcareous earth was precipitated ; which shows 
that this water contains aerated calcareous earth, and selenite. 
EXPERIMENT IX. 
By adding aerated volatile alkali, magnesia and calcareous 
earth were precipitated both from the fresh and the boiled 
water. 
EXPERIMENT X. 
Caustic volatile alkali precipitated both magnesia and cal- 
careous earth from the fresh water ; a proof of its containing 
these earths in a state of combination with the aerial and other 
acids. 
EXPERIMENT XI. 
i - , 
Caustic fixed alkali precipitated from the fresh water 
aerated magnesia. (It is to be observed with regard to this
