Afsuming [Assuming] atoms to be unchangeable, porosity may be illustrated in many ways If water and alchohol [alcohol] be mixed 100 parts of the one and 66 of the other. The mixture will only measure 162 parts, and so of other mixtures proving that they partly fit into each other’s pores. Atmospheric air is so porous that 1500 cubic inches has been comprefsed [compressed] to one inch, [again] one inch of water will make 1728 inches nearly when converted into steam. All bodies may be comprefsed [compressed] by sufficient force. The comprefsibility [compressibility] of bodies is their susceptibility of having their atoms brought nearer each other.

All bodies may be reduced in volume by prefsure [pressure] or nearly in all cases by a removal of heat.

The modified results of cohesion are Hardnefs [hardness] Bitternefs [bitterness] Flexibility Tenacity [malleability] and [ductility]
