appeared hopeless, has been treated with
lnha'ntions of this gas, with results dc.
scribcd as marvellous. After months
treatment the appetite was rcgaincd, the
sleep calm and refreshing, and there wa,
very good prospect of recovery. The
ozone was prepared by passing stream
OF oxygen through the current of an in.
