the process, OF timing the pipes The opinions OF these
they agree in condenng the use IF ordinary leaden pipes
for the conveyance water as dangerous TO health IN con-
crust Of oxdized lead which thss produced They c.n-
slider the Of eaden pipes most dangerous when iae
water is remarkably pure Dr. Elet states that leaden

oxidiza,os He experimental with the ppres water while
residing in South Carolina and found such tendency to
oxdizaton satisfied aim of the danger OF using eaaen
pipes Tbe Croton water very pure and therefore the
of leaden pipes ought by all means to be avoided.


Dr. Chiffon recently inspected the Croon water drawn

they willing to furnish the Corporation OF the City with

pound From all the information obtained, and all the re-
hecton bestowed by your Committee upoa subject OF no
little Importance, as connected with the health and comfort
oour citizens your Committee have arrived at the follow
ing conclusions That the Of the ordinary eaden pipes
for the conveyance OF water when as pure as
the Croton is decidedly dengero and therefore ought TO
avoided The danger would be less where the pipes
small 10 circumference and in daily use, and greater where
ted remain unused for any considerable space of time
The internal coating of tin will be secure protection
again the oxidzaton OF the lead The timed leaden
pipes of the petitioners altogether superior 10 the ordi
nary leaden pipes and deserving OF public patronage
Your Committee therefore recommend that these timed
eaden pipes bt adopted for the conveyance Of tie Crno

ry leaden pipes.
Your Committee offer for the consideration of the Beard
the following resolutions:
Resolved, If the Board of Aldermen concur, That the
Joint Committee ths Croton Asueduct be instructed to
make of Naylor Ewbank's patent timed eaden pipes
for the conveyance of the Croton water into the public
