cially of the chlorides, became more rapid than the forward 

 movement due to capillarity, and the result was the salts dimin- 

 ished at the top after a certain relation of concentration to the 

 rate of capillary movement had become established. 



The mean rates of accumulation of the most soluble salts 

 chlorides, nitrates and sulphates as shown by the examina- 

 tions made on successive dates, are given in the next table, 

 where the mean intervals of time during which capillary move- 

 ment acted in effecting this distribution, are also given. In 

 the same table are given the corresponding data for the phos- 

 phates, by way of contrast. 



Mean distribution of water-soluble salts, as affected by capillarity r 

 at the close of different intervals.
