45. The experiments of HENRY and DONNY have shown that the cohesion 

 of liquids, as far as their antagonism to rupture goes, is much 

 greater than has been generally believed. These experiments, 

 however, make no difference hi the view I have put forth, as, what- 

 ever be the character of the attraction, there is a molecular attrac- 

 tion to be overcome in changing bodies from the solid to the liquid 

 state, which must require and exhaust force.
