paper on tlielitoio tow, prt;ht-Vptesti a hot iron ;
and on the part which had shrunk, by which they t
were returned' to-.their original shape, bttt-not- till
he had discovered,. by infallible means, the degree.
of heat which the iron ,ought :to posses, before it
was permitted to approach the Pittute„ -
'We haVe seen Olathe had fixed the Painting, dis-
embarrassed tVom its impression, on the paste, and all
other foreign substances,;on an impression in oil, and :1
that he had restored to a smooth form, the shrunk
parts of its surface ; but the chef d'ezavre still re-
mained to be done„ namely, to fix the Picture solid-
ly upon a new ground. For:this purpose he disen-
gaged the gauze, which had heen.provisorily placed
on the impression, added a new coat of oxide of lead
and oil—applied a gauze,,fentlered very supple,
and upon that placed another preparation of lead and
an unbleached cloth cut in one piece, and impreg-
nated, on the exterior surface, with a resinous mix-
ture, on which- was,fixed a similar cloth fixed in a
frame. The body of the Zidufe, disembarrassed from
what had been previously placed on it,
.and furnished
with a new ground, was then applied, with exadness,
to the cloth, impregnated with the resinous sub-
stance, avoiding every thing that might injure it by
too great or unequal extension, and forcing all the
points of its extent to adhere to the cloth fixed in
the frame. By this process the Pifture xvas incor-
porated with a base moire durable than the first,
.and fortified against those accidents which had pro_
duced its 'deterioration, since it has been finally re-
stored, which is the objet of the second part 'of this
Rel.3ori.
This second operation, which we will call Pidu-
resqUe Restoration,' was confided by-the Admini-
stration to itizen RCE'iER, to whom we-ate in-
debted for the reparation Of the-Most valuable Pic-
tures, and whose success multiplies the motives for
confidence. The Commissaries, after havirig pointed
out the process employed for this purpose liectare,
that it is as perfeft as it was possible to desire, and
thus conclude their interesting Report.
" We felicitate'ourselves on having at length seen
this thef d'arp-ure of the immortalißAPH AV. rest -
red to existence, in all its.primitivebeauey, anti by
such means as' leave no room to tear the -return of
accidents, whose ravages threaten the objects of ge-
neral admiration."

The Administration of the Central Museum of
the Arts, who, by its'Science has perfeaed the art
of Restoration, will, doubties's, neglect nothing to
preserve the Art in ail its integrity, and in spite of
reiterated success;' it will not suffer the application
Of the Art to obje&s, unless they. sre sib deteri4-
rated, that it will be better to run the. risk
table from delicate and tnultiplied cperatitms, the n
to abandon them to the destruaion with which
their_ are tnen-aced, The invitation which the-Admi-
nistration of the Museum has made to the National
Instititteito follow the process of Restoration with
respea to'the Piaure of It.:‘}';-lAE I, is a sure,zug-
yantee that the enlightened inen who compose it,
feel that they ought to render an account of their
condua to the whole of enlightened Europe.
