32. 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 ex- 

 periments, however, make no difference in the view I have put 

 forth, as, whatever be the character of the attraction, there is a 

 molecular attraction to be overcome in changing bodies from the 

 solid to the liquid state, which must require and exhaust force.
