lower than the temperature at which the flash has been
previously obtained. If necessary, this procedure shall be
repeated with fresh portions of oil until a flash has been
obtained at a temperature not within 8 degrees of the tem-
perature at which the testing was commenced.
5. The temperature at which the last-mentioned flash
occurs is the observed flashing-point of the oil, and by
correction of the observed flashing-point for atmospheric
pressure, as hereinafter described, the true flashing-point is
obtained.
6. In repeating a test a fresh sample of oil must always
be used, the tested sample being thrown away, and the cup
must be wiped dry from any adhering oil, and cooled, as
already described, before receiving the fresh sample.
7. If in any case no flash has occurred when a temperature
has been reached which is not within 8 degrees of the tem-
perature at which the testing was commenced, and which,
after correction for atmospheric pressure, is not less than
73 degrees, and the tests are not required to be continued,
the oil shall be deemed to have a true flashing-point of not
less than 73 degrees.
8. If no flash has occurred when a temperature has been
reached which is not within 8 degrees of the temperature at
which the testing was commenced, and which, after correc-
tion for atmospheric pressure, is not less than 100 degrees,
and the tests are not required to be continued, the oil shall
be deemed to have a true flashing-point of not less than
100 degrees.
9. In the same manner, if no flash has occurred when a
temperature has been reached which is not within 8 degrees
of the temperature at which the testing was commenced,
and which, after correction for atmospheric pressure, is not
less than 150 degrees, and the tests are not required to be
continued, the oil shall be deemed to have a true flashing-
point of not less than 150 degrees.
V.-CORRECTION FOR ATMOSPHERIC PRESSURE.
As the flashing-point of an oil is influenced by changes in
atmospheric pressure to an average of 1·6 degrees for every
inch of the barometer, a correction of the observed flashing-
point is necessary whenever the barometer does not stand
at 30 in. This correction is to be made in the following
manner:-
If the barometer stands at less than 30 in. (the normal
height of the barometer), add to the observed flashing-point
1·6 times the difference (measured in inches) between the
actual and normal barometer. If the barometer stands
above 30 in. deduct from the observed flashing-point 1·6
times the difference between the actual and normal barometer.
The nearest whole number to the result of this correction
is to be taken as the corrected flashing-point, and if the
result is exactly midway between two whole numbers the
higher whole number is to be taken.
For example: Suppose an oil has an observed flashing-
point of 72 degrees, the barometer being 27·1 in., then the
difference between 30 in. and 27·1 in. is 2·9 in. This result
multiplied by 1·6 is 4·64, which has to be added to 72, making
76·64. The nearest whole number to this is 77 degrees, which
is to be taken as the corrected flashing-point, and if the
testing had been commenced at or below 64 degrees, the true
flashing-point is 77 degrees.
Again : Suppose the observed flashing-point of an oil to be
96 degrees, and the testing had been commenced at 87 degrees
and the barometer indicated 30·6 in., the true flashing-point of
the oil is the nearest whole number to 96 minus the product
of 0·6 multiplied by 1·6--that is, 95 degrees.
The readings of the barometer are to be corrected readings,
in accordance with the corrections applicable to the instru-
ment in use. The instrument must be compared periodically
with the standard barometer at the office of the Chief Inspector,
and regulated thereby.
VI.-APPLICATION OF THE TEST TO VISCOUS FLUIDS OR
PREPARATIONS.
If the flashing-test has to be applied to substances of a
viscous or semi-solid nature which cannot be poured (such
as solutions of indiarubber in mineral naphtha), the mode of
proceeding is as follows :-
One fluid ounce or two tablespoonfuls of the substance to
be tested is placed in the cup, and the cover is put on. The
air-chamber in the water bath is filled with water to a depth
of 1 in., and the temperature of the water bath is raised
to 90 degrees. The cup is then put into the bath, and the
temperature of the water bath maintained at 90 degrees
throughout the test. After the lapse of fifteen minutes the
test-flame is to be applied. If no flash occurs the heating
is continued for another fifteen minutes and the test-flame
again applied, and so on until a flash takes place, or the
temperature in the cup has reached 90 degrees, and so on.
The temperature at which a flash occurs is the observed
flashing-point of the substance, and, subject to correction
for atmospheric pressure, as hereinbefore described, is the
true flashing-point.

ORDER IN COUNCIL.
At the Government Buildings at Wellington, this 21st day of
April, 1921.
Present :
THE HONOURABLE SIR F. H. D. BELL, K.C.M.G., PRESIDING
IN COUNCIL.
WHEREAS the Kiwitea County Council, acting under
and in pursuance of paragraph (e) of section sixteen
of the Local Bodies' Loans Act, 1913, lately proposed to
raise a loan of three hundred and fifty pounds for the pur-
pose of road-formation and building a retaining-wall at
Brown's Slip :
And whereas the ratepayers' consent given under para-
graph (e) of section sixteen aforesaid is irregular, in that a
subscribing ratepayer has attested the signatures of the other
subscribers thereto :
And whereas it appears that the ratepayers have not been
misled by the said irregularity, and it is expedient to validate
the same :
Now, therefore, His Excellency the Governor-General of
the Dominion of New Zealand, in pursuance and exercise of
the powers and authorities conferred on him by section one
hundred and eleven of the Local Bodies' Loans Act, 1913,
and acting by and with the advice and consent of the Ex-
ecutive Council of the said Dominion, doth hereby order and
declare that the ratepayers' consent to the raising of the
said loan shall be valid to all intents and purposes as though
the same had been properly witnessed, and that the validity
of the proceedings in connection with the said loan shall not
be called into question by reason only of the irregularity
aforesaid.
