Nefa'ic Poisons.-An interesting note, frp, M.
VI. Danger aud Flandin, on the effect of n,etal.
lie Poisons, was read before the Faench Academx
OF Science in September. Several og the best.
French chemists have recorded in tEeir works tbs

the human body in its normal sta,e, and IBIS ~
sertion has still numerous advocates. Ae- "a
ing to the experiments of NJ. NJ. Danger ,i.
Flnndin, the assertion is not borne out By Gu refat
analysis. But the most Interesting portion of ,a;s
paper is ar account Of experiments performed on
ANIMALS, with view to ascertain the precise ac.
ton OF the absorption Of poisons, and tho race,
which they give in post mortem examina,iop.-,
These gentlemen administered to dog daily. loi
several months, as much sulphate Of copper ar
could be given without causing death or ,srioos
injury. and then having destroyed tie anifea'f
proceeded to operate upon tho blood and al she o
gans in the most minute and careful nay The
only organ in which any M, Of the ro son Eas
found was the liver, and even there i. vas onIv
barely preceptiSle. Reasoning by analogy. they
assume that this would also be the case with the
human system, n,'d, if this be true, ma ny Of tho
experiments dePosed to in courts of law must have
been founded in error. It appears, also, that the
result is the same with lead and many other pois.
ons, If an interval ofthree or four days has clans.
ed between the taking Of the poison and the death
OF the animal, the absorbents in that time carry
ing the poison to the intestines, from which il il
discharged with the excretions.
