NJ. Gay Lussac gives account Of the theory of
NJ. Msgnus relative 10 the chemical phenomena OF
respiration According 10 this theory the oxygen Of
the air IS absorbed the of breathing by the arie-
nal bleeding IN The lungs and from thence carried
to the circulation 10 It's passage, and by means Of
capillary tubes, certain quantity combines partly
with carbon to form carbonic acid which remains in
solution IN the blood and partly with hydrogen form
water The blood thus CT arged with carbonic acid
and transformed into blood, arrives IN the
lungs, where 1t sbsndons 10 he air carbonic acid
again takes up oxygen and, transformed into arteria
blood, Commences a revolution The expefi-
men's made by vi. Magnus confirm his theory TO
certain extent, but are not considered by Nj. Cav
Lassoc 10 he conclusive lie intends, in ooniunotion
with VI Moendic, TO examine anew aud with great
care, all the chemical phe nomena ofrespiration
NJ. Ro seau presented the academy with the model
of an apparatus for fterng Urge scale the water
used IN Paris His plan Consists # a number of

matter conhned between wire the water passes over
these beds and deposit It's impurities The Academy
appointed committee TO report on NJ. Rosseau's in

A paper received from Nj. Oriila in reference
TO a recent communication from Messrs. Danger and
fandin, On the localizaton Of po'sons. These gen
tlemen had stated that where sntimouy had been in
troduced into the body, II would be found in Inc
liver the spleen, the loins and the urine-and not IN
tho lungs the heart, the brain, the muscles or The
bones that copper would be found 10 the liver The
spleen and the intestinal canal 20 The exclusion NJ
all the other organs and that lead was neither 10 he
found IN the heart, nor the nervous muscular or os
scous ~ tens. NJ Orhla, when he first heard NJ
this communication - represented 10 have expressed
bis dissent from it-but IN the paper which he has
lust sent IN, he admits the ocazation of poisons and
c aims TO have been the first 10 declare II He says
that the 10th Of March, ls4O. when the nanes
Of NM. Flanoin aud Danger rad not been heard N
be read 10 the Academy Of Medicine a pap.r in
which be stated that anthony was 10 be found in
the liver, aud that the heart and lungs scarcely con
tanned any, and that tartar emetc and arepous acid
(arscnic) emained longer, and in larger proporons
m the secretiye than IN the other organs Nj Or6la
seems 10 consider that the reseaic hes Of MN Fts,
din and Danger are but 40 application of his own
discoveries.
