M. Cocao n recently called the attention of the
French Academy of Science to a lingular ac
cident that had occurred a thort time previously
in hie laboratory. Eight daya ago, said he, my
laboratory beoamo tho acene of a sudden outbreak
of tire. The board flooring in the neighborhood
of a itove spontaneously ignited. In con
sequence of a similar accident, two years ago, I
had caused the board in the vieiuity of tho
stove to be replaoed by a marble slab. Not
withstanding this precaution tho lire broke out
in the wood around the marble. The heat to
whioh the wood was eipoeed at the points
where it ignited was not very great; the air had
only a temperature of 2ft. But without doubt
there had been a slow carbonisation of the wood
and a rapid absorbtiou of the oxygen of the air,
ami in conseiueuce a production of caloric
ufliciout to cause the combustion. Herein lies
a dauger which should be impressed on the
minds of architects and builders.
This reminded M. Faye of a caso of spon
taneous combustion that had recently occurred
at the house of a friend of his al Passy. The
lire was due to the continuous action of the
heat of a stove on the surrounding wood-work.
M. Dumas adduced several analogous exam
plea, all of whioh he explained by that property
of finely divided bodies whereby they absorb
air very energetically and generate heat. In
powder factories, for instance, the pulverised
carbon very often ignites of itself. It is for this
reason that the practice has been generally
adopted of pulverixiug it in conjunction with
sulphur, because sulphur deprives it of the
property mentioued.
In such instances as those cited, the wood de
prived of ita moisture by long exposure to heat
becomes transformed into a substance analogous
to lignite or peat. In fact, it ia changed into a
coudition that may be oompared to that of pow
dered wood. In this state it condenses the air
and take Are. It was thus that, on one occa
sion in his experience, a beam in a ooach-house
exposed to hot air took Are spontaneously.
Sometimes in theaters the lainpmeu's box, Ailed
with miscellaneous oily rubbish, becomes spon
taneously ignited. The greasy odds aud ends
contained therein condense the oxygen of the
air. In manufactories where Adrtaunple red ia
applied on cotton impregnated witn greasy
in ate f ml, spontaneous combustion takes place
very uften.
M. Unman cited one more singular fact of
which ha was a witness in the at mho of a paint
er. The artist had taken a piece v' ootUn to
brush and clean his canvas. He gave the oily
surface a good rubbing and put the oottoa aside.
Very soon the cotton ignited spontaneously.

The engraving on this page shows an old Mis
sion near one of the oldest towns in tho United
States, Tucson, Arizona. This Interesting relic
of the xeal aud enterprise of the padres was
photographed by Mr. E. Conklin, and an en
graving from the photograph appears in Ilia
"Picturesque Arizona," pnhliahod by the "Con
tinent Stereoscopic Co.," of New York city,
The Mission is named San Xaviar del Bao, and
although nearly 200 years old, according to Mr.
Oonklin's reckoning, it is still in a good state of
preservation, aud is opened for religious sor
vices to the natives, " a half-civilised remnant
of a mixture of the Mexico-Indian blood." It
is the best preserved Mission ruiu in the Terii
tory, and is oua of the boldest of its class iu
design and moat elalmrato in construction. A
recent visitor givee a description of the structure,
which we reproduoe to accompany the engraving:
Nine miles distant from Tucson, dowu the
valley, is the old Mission church of St. Francis
Xavier, which is MM of the greatest objects of
interest in tho country. It wsa built about 2110
years ago by a community of Franciscans.
It is a spectacle to make one shudder la spite of
himself. There are still 74 life like atatuea of

monks or their Indian prose ly tea from the mines.
The altar service, w Inch Is also ol solid gold,
waa carried away a few years ago by some priests
who came from Mexico (or the puruawe, and
there are but two small vessels lelt to show
what the other and larger pleoea must have been.
