PREPARATION OF SULPHATE OP PHYLLERENA. 327 
ART. LXX.-— PREPARATION OF SULPHATE OF PHILLYRENA 
A NEW FEBRIFUGE. 
Prof.. Jachelli, of Ferrara, has proposed the introduction 
into the materia medica, of the Phillyrea latifolia, and sul- 
phate of Phillyrena, as a febrifuge. The incised phillyrena 
(6 kilogr.) is boiled for two hours in water (50 kilogr.) and 
concentrated sulphuric'acid, (250 gram.) The liquid is filter- 
ed hot. This is repeated three times to exhaust the article. 
The decoctions are mixed, allowed to cool, and neutralized 
by lime. The precipitate is thrown on a filter and washed 
with cold water, then dried at a temperature from 40° to 
50° R. It is then digested over alcohol at 36°, boiled for an 
hour in an alembic to collect the excess of alcohol; filtered 
while hot, the alcohol evaporated, and diluted sulphuric 
acid added to saturate the phillyrene. In a few days 
crystals will be deposited, which may be purified by animal 
charcoal. These crystals present the appearance of silken 
flock-like asbestos, of a light bitter taste. It is administered 
in the dose of three-fourths to one gramme in the apyrexia 
ten to fifteen grains. — Uaheilk Medicale.
