(fig. 395) 15 6 



Fig. 395 shows a simple Apparatus for testing Petroleum to ascertain the 

 temperature at which it gives off inflammable vapour. It consists of a sheet-iron 

 vessel to hold the Petroleum to be tested ; this is placed in an outer vessel to hold 

 water (somewhat in the manner of an ordinary gluepot) with a metal support, so 

 arranged that the water can be gradually heated by a Spirit {Lamp, and the 

 temperature of the Petroleum conveniently observed by a reliable Thermometer.

 An Act to continue and amend the Petroleum Act, 1871. [August llth, 1879.] 



1. This Act may be cited as the Petroleum Act, 1879. 



This Act shall be construed as one with the Petroleum, 1871, and together with that 

 Act may be cited as the Petroleum Acts, 1871 and 1879. 



2. Whereas by the Petroleum Act, 1871, it is enacted that the term " petroleum to 

 which this Act applies " means such of the petroleum denned by that Act as, when tested 

 in manner set forth in Schedule One to the Act, gives off an inflammable vapour at a 

 temperature of less than one hundred degrees of Fahrenheit's thermometer, and it is 

 expedient to alter the said test : Be it therefore enacted that 



In the Petroleum Act, 1871, the term " petroleum to which the Act applies " shall mean 

 such of the petroleum defined by section three of that Act as, when tested in manner set 

 forth in Schedule One to this Act, gives off an inflammable vapour at a temperature of 

 less than seventy-three degrees of Fahrenheit's thermometer. 



Every reference in the Petroleum Act, 1871, to Schedule One to that Act shall be 

 construed to refer to Schedule One to this Act. 



Petroleum Act of 1879 giving description of the above Apparatus and instructions 

 for using it, price per post, 6d.
