The possibility of poisoning from ar
senic in the soil has been studied by
Messrs. A and A F. Angel. British
chemists. The arsenic impurity of
superphosphate of lime was increased
TO one-half of one per cent, about l.
times the usual proportion. and thl-
manure was applied To various crops
in two lots-part at time of sowing an
part when the plants were we'll aboN

senic was drawn up mechanically inJ
the young leaves of rhubarb and In
grasses and into the green pods -
beans. but no trace reached the fru
or seed of any plant.
