After the announcement OF the subject and read
pg OF the Rules of Order, the following facts were
lcited:


Water as q Solpsnt.-It was stated that the ma
ural water Of this Island, particularly that furnished
by the Manhattan Company, contained large guam
titles Of lime and other alkaline matters, which pre-
occupied ihe powers Oft the water as solvent, and
thus rendered il unfit for many uses. 1t was stated
that seven hundred pounds pure water required
to dissolve one pound of lime and Of many of the
earthly products a much larger quantity was re-
quired FOR the solution Of single pound; and there
fore, that water containing these substances even
in small degree, not suited to the use Of the
brewer, tho soap-maker, the distler, the dyer, or
the maker of extracts Of any kind, the water not be-
ing left free from the presence of foreign materials
TO exert its entire force as solvent.


The use of water to the Brewer is to make an ex-
trac, from the Lupeline of the Hop and the Sac
charine or Sugar oil Ala!t of the Barley; and the
quality Of his product depends upon the amount Of
these materials dissolved in given amount Of wa
ter. For this reason the water of the Thames has
enabled tho London Brewer TO supass all others in
the qualify of porter.


Prior 10 the introduction of Croton water, Phila-
delphia porter and ale very superior to thai
made IN this city. The difference of quality was
entirely due TO the excess OF lime and other matters
oontaioed in the water of our island. We now
manufacture malt liquors Of superior quality 10 any
manufactured in the United States.


la the manufacture OF extracts for medical pur-
poses, SO large qaantty OF water is required 10
dissolve email amount OF the active principle OF
many plauts that by The time all the water was
oyaporated for the purpose Of bringing the extract
fo solid msss, tue result was compound o; the
impurities of ,ha water, tho medicinal properties OF
which, in many cases, were incompatible with the
supoosed properties of the extract OF the plant and
thus rendered il useless as & medicine.


For pharmaceutic operations generally, impure
water intereres with the che ical rationale anuci-
pated.


ia very important. /, enables him 10 form solution
OF true stesrate, which, when eyaporaed TO proper
degrees of solidit, forms soap capable Of sustaiI-
ing its 6sure in any climate.


Those eng aged 10 the making of extracts OF log
wood and other dye-wosds intended 10 DO sold IN
tas concentrated solid iorni, are also highly ben
efited for, previous to the use OF Croton water fol
This purpsse the presence OF lime and msgnesis
rendered their celOrs neutral and dtngy, instead
clesr and brilliant.


Tha Di5tiiI6r is now enabled 10 carry MS icrrcen
,ar;on 10 such an extent as 10 consume all his
.scchsripe. The Ssgaf-Rehaer is no longer an
moved with tbs presence of deilquescent salts in hi
Ts.alis: and his product will, therefore, be more ii
demand for Southern climates than when subject It
become soft us was the case when orscksh wate'
was used as solvent.


From ali lhese facts, i, is not only evident that
,,rper sn,ounr Of material may be dissolved IN les
waer la, rhe. the result ebta,aed alter evaQorahtl
will orcsssafily be Of better Qualities.


For household purp4 p4ses, the Croton IS Invaluable

washing. the mora ready removal OF dirt by pure
,b.n by impure water. are alone sutcient t9 have
varranted the libcfal outlay which mas been eS'
nended on this great work.


Every one must be aware o! the entfe impossi-
h;ty Of washing even once hands IN cola westne'
