Taking the cohesion-figure of creosote as a kind of measure 

 or index of the adhesive force of the surface of water, it appears 

 from the foregoing details — 



1. That the creosote may be rendered inactive by heat. 



2. That the adhesive force of the liquid surface declines as the 

 temperature is raised. This is shown by the creosote figure being 

 either not formed at all, or having, when formed, its duration 

 considerably extended. 



3. That the duration of the figure is increased in a hydrogen, 

 and diminished in a carbonic acid atmosphere. 



4. That the adhesive force of the surface is diminished by the 

 addition to the water of small portions of liquid and solid bodies 

 soluble therein. 



5. That the adhesive force of the surface is diminished or de- 

 stroyed by placing on it a film of some other liquid. 



6. That the adhesive force of a film for the surface of water 

 may be estimated by the displacing-power of creosote, or by the 

 increased duration of the creosote figure.
