diffused through any given portion of space, and the force and 

 elasticity of vapour, as measured by the column of mercury 

 which it is capable of supporting. The means of finding these 

 with ease and precision are furnished by the annexed Table, 

 upon the construction of which it will be necessary to subjoin 

 a few remarks.
