red persons in France win have to be accounted with
who are now claiming the merit Of perseverng research in
the sare direction Thus it would be impossible to dsre
gard the value of the following reclamation Of NJ FaAN-
oHoT who in 1910 had submitted to the Academy me-
moir on an air machine Of his invention which, like
many Others has not obtained the honors Of report
Eighteen years ago (says NJ Franchot) occupied
myself with researches having for object the employment
of the motive of air dated by heat Neyetheless
my first authentic titles do not 90 further back than 1885,
and they consist in the description and drawings of
ar-machine, published in the Journal de PAeadea,c de
PIndustrie, March No. 1885, and by the Bulletin de la
SocsS Idustre de Saint Ehsnns (4h livraison, 1897
In my explanation of this machine already exposed the
idea of exchange of temperature between current of
cold air reaching the moving cylinder and current Of
other separately by plates Of futed sheet iron. Iwas
not till subsequently brevet of l836 that exposed the
more fecitons idea Of causing these contrary
rents to pass alternately through the canal add
ing that it would be well that this canal should be filed
with metallic gauze-work (toles metalliques) with
very minuey divided metal for the purpose Of storing
the heat Now this idea, which believed the first
to emit to play capital role in the economy of the
Ericsson engine. however this may be, having expe
renced the Inconvenience of exposing to the action Of hot
air. the surfaces OF metals performing functions similar
those Of cylinders drawers and pstons tried in 1888
machine which is perfectly relieved from this in
convenience 1t was from the data obtained in that
essay that drawn up the memoir presented in l84O

changed my manner Of viewing the subject"
The note Of NJ FRANcHoT referred also the me-
moir to which allusion is made the examination of
new committee, compossd Of MN. Poncelet, Lame,
Pouillet Seguier and NORM This committee will also
take under consideration work presented in 1886 by
M Burdin Ia
NJ LExoINE, of Rouen also addresses to the Academy
reclamation in support Of his pretension to priority
in the employment of the wire gauze net work He
calls attention the fact that in 1847 he took pa
for fifteen years for ar-machine which in fact
consumed much more than he had hoped. He then
ceved the idea of employing metallic gauzes in order to
enable him constantly to make of the caorc.
This idea appeared to him fruitful Of good results that
he fastened to have it patented which he effected the
I'd September, 1848. M. Lemoine convinced that
the problem solved and that the desired economical
results certain. Unfortunately the machine
already constructed and the system could only be
imperfecty adapted to it. AS in his machine the hot air
saturated with humidity, the condensation of the
humidity in the network produced unforeseen difficult
ty. The new machine then transformed simply into
steam-engine. Nevertheless, NJ Lemoine, continuing
his researches, constantly seeking the Of ui
ring the remarkable property of the wire gauzes and
he calls the attention Of the Academy to last apparatus
which demonstrates the in which the metallic
gauze peforms its functions and the superiority OF sys
em which would have the system of Ericsson the
advantage of developing alternately the effects of
vacuum and of pressure. The reclamation Of M. Le
moine referred to the same committee with M.
Franchots.
NJ L1AIs also claims his share of the merit of an in

main stranger and he demonstrates theoretically that
the quantity of heat intended for of air should be
applied to it previous its dataon in other words that
air should not be heated gradually in proportion as it
dlates but it should be brought to the highest tempera
ture intended for it before it is allowed to date The
rule should be applied in the abandonment to con-
densation of productive heat This principle like those
subsequently treated in his memoir, Mr.. Lias demon
strstss athsaatioaily andindependeny Of any parcu
lar machinery
NJ LIAIs applying the above rules to the engine of
Ericsson is of opinion that works under the most u
favorable conditions and he claims therefore for himself
no share in the invention of the regenerator
NJ FoUcAULT then devotes few lines to the refutation
of report against the Ericsson engine lately made to
the Societe encouragement by M. -GAxALAr and
published in the Moniteur Of the 9th instant NJ F. sug-
gests that the hostile reporter thoroughly
by the idea Of different system that had failed that he
could not bestow upon the Ericsson engine the time and
attention that would have enabled him to understand it,
M. Foucault thus concludes
"From all that have read and heard we believe we
may conclude that science and industry have just
quered great principle, of which the practical value is
not yet well defined but that will later impose
itself upon the world necessary truth and become
ceptbe Of an nfnty Of fruitful and various applications
We have only yet information of the vague cha
racter relative to the qualities Of the caorc engine but
how avoid anticipating from it the best results
when see that on the one hand it is decried, while
the other presented reclamatons for the
honor Of first invention"
