A MEMOIR Of much interest and i'm
portance upon the use of anesthetics
has been communicated to the Paris
Academy Of Science by Mons. Paul
Bert. By experiment with different
an@sthetic agents upon animals he has
been able to ascertain in the case of each
substance what is the quantity just suf-
ficient to cause insensibility and how
much suflices to produce death. He
finds the fatal dose Of chlorform, ether,
amylene, bromide of ethyl and chloride
of ethyl to be always exactly double the
nn@sthetic dose. The range between
. these extremes Mons. Bert terms the
working zone, and he says that mixture
about the middle of this working zone,
.. properly administered, will produce q
safe state Of insensibility, which may be
maintained long enough for any surgical
operation.
