Innate or bichloride of mercury in
water, one part to one thousand. 1t
is often advisable to use the disin-
fectant little stronger and there is
no danger in using one to five hun
dred. Tablets may be obtained from
any drug store, and the number to
be used to produce any strength of
solution is usually indicated upon the
bottle. To be sure that no mistake
is made, ask the druggist how many
tablets to use to produce a solution
of desired strength. When possible,
use rain water, as the slightly aka
line waters in dry counties tend to
precipitate the poisonous mercurial
compound. Also use a glass or nom
metallic container, as tin can or
other metal container may react on
the disinfectant, and remove the poi
sonous principle Corrosive subli-
mate kills the pear blight germ in
solutions in water when 1t is diluted
to one part to 10000; therefore the
above formulae are sufficiently
strong and well within the limits.
While there are other disinfectants
which may be used, bichloride or
mercury is far the cheapest, and
there is nothing gained by using any
thing else. The use of kerosene, gas
oline, and such like, Is certainly not
permissible. Even carbolic acid is
distinctly inferior to corrosive sub
Innate and, besides, its noxious smell
and burning tendency do not war
rant its use. 1t must be remember
ed, however that corrosive sublimate
Is a deadly poison when taken inter-
nally, and the bottle or container
should be plainly marked POISON" 4"
Applied externally to wounds or up

tools and cut limbs The greatest
care should be taken in emptying
the bottles containing the solution
when returning to the house, other
wise keeping both the bottle and So

there Is no danger in getting the So
