prove deleterious, through its suspended metallic compounds. In order 
to avoid the poisonous effects of these salts, perfectly well-ripened and 
clear spirits only should be used in the preparation of medicines, and 
when ordered as restoratives, no new or turbid alcoholic fluids should be 
allowed to enter the hospital or room of the patient.” 
r, Elayes explains the origin of these salts as being connected with 
the production of acids, as well as alcohol in the fermenting vats. “ When 
the wort is subjected to heat in the still, acetic, butyric and other acids 
rise with the vapor of alcohol, and pass into the condenser, now most 
commonly made of copper, with masses of solder containing lead. At 
the instant of condensation, these acids exert a power of corrosion on the 
metals quite unsuspected, and the salts formed dissolve in the spirit, 
water from the same original source were unaffected, and having in one 
t be obtaine 
from a specimen of the same aqueduct water taken from another locality, 
to the cause which produces this lead 
supply remain unaffected. Ile has noticed in the leaden pipes hs er 
from cess-poois, sinks and wells, that the intensity of corrosive action | 
been in great measure confined to the sharpest bends an sapenegs 
in the pipe, while in some instances other portions remained intact. “
