to change the craving for drink into

200 drops Of water, and injecting five
drops Of the solution every twenty-four

The plan has been proposed by n
competent authority in such matters
that in order to insure greater strength
and consequently more safety in ropes
used for scaffolding purposes-part;cu-
larly in those localities where the at
mosphere proves destructive OF hemp
fiber-such ropes should be dipped
when dry into a bath containing twenty
grains Of sulphate of copper per litre
of water, and allowed to soak in this
solution some four days. BY pursuing
this method. which is claimed TO be
much moro practicable and effective
than any other yet resorted to for this
purpose. it is found that the ropes will
thus have absorbed a certain quantity
of sulphate of copper. which will pre-
serve them for some time both fro N the
attacks OF animal parasites and from
