Use In Dealing with the Plague.
From the Ner Orleans Times Democrat.
Local medical circles are excited over the dis
covery Of n successful manner of ascertaining
whether or not a patient has yellow fever. The
discovery was made here in New Orleans by
local physicians. and n sufficient number Of sue
cessful experiments have been made to invest
the tests in the minds OF physicians with an
Importance second only to the discovery OF o yell
low fever preventive.
The whole matter came out ut the last mcet.t
ing OF the Orleans Parish Medical Society OF
Jan. 90. which vas probably the most Important
| and largely attended Of any In the history Of
that organization. Several valuable paperA
were read and discussed: chief among, which,
was the papeT OF DTs. P F: Agchinard, the emiS
strator OF bacteriology Of Tulane University.
