their sense before they were redacedto writing; wit-
ness took down the answers of Muller, the parts in the
first person art Muller's precise words; the rest is ,
the substance of the examination; after repeated qnes -
lions, which Muller understood, though he was
not very fluent in his answers; the examination
was read over to Muller, and Witness and
Mr. Walker perfectly assented to the correctness
of what was taken down, being aware of its im-
portance ; Mr. Locker was present daring this time;
Muller made no complaint on the examination being
read over to him of any incorrectness, and Buckhorn
assented to what he knew at the same time; witness
and %%rattier compared their different transcripts of the
examination, and the result of the comparison was,
that there was no material difference be;ween them ;
Muller repeatedly denied that oil was used by the
51 eftsrs. Severn : when Mnller denied that oil was on
the premises, witness turned to Mr. Walker, and said,
be had better caution time witness (Muller) to speak
the truth ; Walker. desired Muller to speak the truth,
as Messrs. Severn wished to deny nothing, on th it
Muller changed the character of his evidence, Lnd
went Minion. fluently than before.
John Luckey sworn.—ls Surveyor to the Phomix
Company ; was at the other on the day following• the
fire ; has beard the evidence of Mr. Jones ; way pre-
sent during the examination of Muller; the greater
part of the questions were put by Mr. Jones; the
statement of Mr. Junes is, to the best of his rerollec-
tioa, correct.

t hristophe is a bricklayer : knows Mr.
Wilson; recellerts him setting np a boiler at Craven
and Boner's; witness was employed in setting it up ;
it W. 15 used twelve or thirteen times, chiefly by way of
experinsent : it was put np in a place railed the ma-
gazine; that is a detaches' building; there is a space
of 19 feet between the ma_szine and sug.ir horse;
the machine was never used exrept when Mr. Wilson
was there ; un oni• occasion witness made the fire be-
fore Mr Wilson rune, I.ut the heat did nut exceed
2110; Mr. Wilson Walk semitones' to carry the heat op
as high as 329 ; the highest point that it ever was
got to was 419: the pomp stopped whilst the pan was
discharged and recharged, and during that time the
heat ruse to 500; sloes not know what quantity wf
oil was its the bolter ; when the oil was at 500 the
pipe burst ; the pipe was Made of pewter ; the pump
was then stopped, and the oil got amongst the slicer ;
witness then threw water on the lire, soil the heat of
the oil rose to 600 ; from the time when the pipe
Borst, to the raising of the heat In Bell, about half an
honr might have elapsed ; never saw the oil rome
from the top ; be saw some oil come from one side
where the barometer was placed.
Alexander Smith examined by Mr. Pot.t.orz.--!te-
mesnbers attending' au Experiment at the how* of
Messrs. Taylor and ;Martineau ; the experiment was
carried un at Whitecross-street ; he first received or-
ders on the 7th of March; the oil from Messrs. PHI-,
cher was used in the experiment; be first placed 14
gatlons in the boiler; on the sth of March the fire
was lighted, sail it continued lighted for 23 days;
he was directed not to stiffer she beat to irolabovr 3611;
he was usually employed twelve hours a day; the se-
cond experiment was commenced on 296 of April;
tin this 0,-casion 25 gallons of oil were put into lb,
boiler: the lire under this was continued 22 days;
he kept the hest under 365; at the same time a
smaller boiler had been filled and the same process ob-
served ; the next experiment which witness tnperin-
tended commenced on the sth of Jaae; he did not
know the quantity of oil ensplyyed ; the fire on that
occasion was lighted twenty-three days; all the ezpe-
lriments were tried in Whitecross-street.

James Larkumn examined by Mr. POLLOCK.-Ile-
collects attending an experiment tried at Bromley ;
the experiment was commenced on the 9th of Nl.iy ;
the boiler was three fret long, IN inches wide, and l.i
inches deep; Dr. Boslork and I other persons
were present ; the fire was continued for 31 days.

Isaac Hearne was examined.- —Attended to watch
the experiment mentioned by former witness; the tem-
p
erature observed was 360 degs.; the highest point
Ito which it reached was 360 ; it took witness half an
hour to get the heat up to 3611; in last September '
witness watched another experiment; on the latter oc•
casion 3150 was the highest degree of temperature ;
the boiler leaked ; and great difficulty ensued to pnt
out the blase which it occasioned ; he found it diffi-
cult to keep the temperature at 360 degrees.
Michael Perraday wade chemistry his study for the
I last seven years ; has made exrerinients upon oil ;
is acquainted with the commork process of boiling
sugar; is also acquainted with the process used by
Mr. Wilson ; thinks the ace of oil more dangerous
than the common method ; he first made experi-
ments on this subjects in Feb. 7. 1820 the first
experiment was ;smile with oil which had been pre-
viously heated for 22 days ; the boiler was three
feet by 25 lack.. and 14i inches deep; into this
boiler, 24 gallons of oil were pat it was a elate
boiler. made almost in the same manner as the mo-
del before him ; believes that the nature of oil is
rendered more intiamtuahle by being many days
heated; if oil he repeatedly distilled, it becomes
much 1110,0 volatile, as naptha ; .it lemore volatile, and
rises iuto • vapour much more easily than common oil ;
, oil may he rendered so volatile. that at the common tem-
perature of the atmosphere the vapour will take fire ;
this is produced by. distilling oil only twice ; satis-
fied that oil thus distilled is more intlaminable than
in its natural state; is the experiments which he
made, his first ears was to 'ascertain whether this
volatile oil could be produced at a temperature of
360 degrees; when oil. which had been heated es t
360 was increased to 410, it yielded some portion}
of the volatile oil; never ascertained the point at
which oil would boil, because in srnod thernieme-
tars the saercnry will boil Wore the oil ; the result
of his experiments on this head was, that there was
im difference of *OO between thetemperalure et whittle
fresh oil and oil previously heated would produce se-
ladle oil. At 360 deg. the are was to 410 deg. ib I
