Conclusions. — First, the above data seem to indicate that within cer- 

 tain limits the cohesion of water with dissolved salts in it is a function 

 of the concentra- 

 tion. 



Second, as far 

 as tested all di- 

 lute solutions of 

 salts in water ren- 

 der the cohesion 

 of the solution 

 less than that of 

 pure water. 



Third, so far as 

 tested the dilute 

 strongly basic 

 salts produce a 

 greater decrease 

 in the cohesion of 

 the solution fx-om that of pure water than the nonbasic salts. 



Fourth, it is also noted that before the point of saturation is reached 

 in the strongly basic solutions, increased concentration does not produce 

 increased cohesion. 



Tests are in progress with various other salts than the ones referred 

 to above. Also tests are in progress in which other solvents than water 

 are being used.
