Year: 1862

The City Councils of Philadelphia are,
just now, terribly exercised about PROPOSE
tion of the passenger Railway companies to
spread salt over the tracks OF their roads
to prevent the accumulation of ice aud snow |
during the winter. The city fathers are
afraid that salt is unhealthy when put upon
the streets, and laboring under the inau-
ence Of this fear, wish to avoid any infringe
ment of the sanitary laws Of the city by
granting the requested permission to the
posing the aforesaid railway corporations,
are not so well satisfied that salt is unwhoe-
some, and are willing to have the matter in
quired into by competent authority conse.
quently on Monday last committee Of
Council heard, in solemn meeting assembled,
the good and bad qualities Of salt gravely
set forth, by those whose business it is to
know how salt will behave itself in public,
while enjoying the compaDionship of the
Heecy fallen fakes Of snow that so much
impede the travel and deplete the treasu-
ries OF the passenger railway companies.

in the medical department of the University
of Pennsylvania, eXpatiated upon the vir-


tines Of salt before the committee and gave


some interesting information in relation Ia
