From these figures it appears that the total weight of chloride 

 found is always a little greater than that taken, the mean increase 

 being 0.0005 grm. for sodium chloride, and 0.0002 grm. for potassium 

 chloride. It appears also that the residue left by the evaporation of 

 the decanted and filtered amyl alcohol is greater than the loss put 

 upon the chloride by the treatment, — in the case of sodium chloride 

 0.0005 grm., in the mean, for every 50 cm.^ of amyl alcohol, which is 

 about the quantity employed in the experiments ; for potassic chlo-
