at a temperature of less than one hundred degrees of Fahrenheit’s thermometer, 
unless the bottle or vessel containing such petroleum have attached thereto a 
label in legible characters, stating as follows : ‘ Great care must be taken in 
bringing any light near to the contents of this vessel, as they give off an in¬ 
flammable vapour at a temperature of less than one hundred degrees of Fahren¬ 
heit’s thermometer.’ Any person acting in contravention of this section shall 
for each offence be subject to a penalty not exceeding five pounds.” 
The mode of ascertaining the temperature at which inflammable vapour is 
given off, is described in a schedule to the Act, and is as follows :— 
“ Directions for applying the Flashing Test to Samples of Petroleum Oil. 
“ The vessel which is to hold the oil shall be of thin sheet iron ; it shall be 
two inches deep and two inches wide at the opening, tapering slightly towards 
the bottom ; it shall have a flat rim, with a raised edge one quarter of an inch 
high round the top ; it shall be supported by this rim in a tin vessel four inches 
and a half deep and four and a half inches in diameter ; it shall also have a 
thin wire stretched across the opening, which wire shall be so fixed to the edge 
of the vessel that it shall be a quarter of an inch above the surface of the flat 
rim. The thermometer to be used shall have a round bulb about half an inch 
in diameter, and is to be graduated upon the scale of Fahrenheit, every ten de¬ 
grees occupying not less than half an inch upon the scale. 
“ The inner vessel shall be filled with the petroleum to be tested, but care 
must be taken that the liquid does not cover the flat rim. The outer vessel 
shall be filled with cold, or nearly cold, water; a small flame shall be applied 
to the bottom of the outer vessel, and the thermometer shall be inserted into the 
oil so that the bulb shall be immersed about one and a half inches beneath the 
surface. A screen of pasteboard or wood shall be placed round the apparatus, 
and shall be of such dimensions as to surround it about two-thirds, and to reach 
several inches above the level of the vessels. 
“ When heat has been applied to the water until the thermometer has risen to 
about 90° Fahrenheit, a very small flame shall be quickly passed across the sur¬ 
face of the oil on a level with the wire. If no pale blue flicker or flash is pro¬ 
duced, the application of the flame is to be repeated for every rise of two or 
three degrees in the thermometer. When the flashing-point lias been noted, 
the test shall be repeated with a fresh sample of the oil, using cold, or nearly 
cold, water as before ; withdrawing the source of heat from the outer vessel 
when the temperature approaches that noted in the first experiment, and apply¬ 
ing the flame test at every rise of two degrees in the thermometer.”
