Alkalinity of soluble and insoluble ash. — This determination is ex- 

 pressed in the number of cubic centimeters of tenth-normal acid neces- 

 sary to neutralize the ash of 100 grams of sirup. For insoluble ash, 

 which is chiefly calcium carbonate, the average figure is 87 cc, the ex- 

 tremes being 190 and 31. Since 1 cc of tenth-normal acid is equal to 

 0.005 gram of calcium carbonate, the 87 cc are equivalent to 0.435 gram 

 of calcium carbonate. The actual average percentage of insoluble 

 ash is 0.36, which is 0.07 gram lower than that calculated from the 

 alkalinity. The average figure for soluble ash is 75 cc, with extremes 

 of 140 and 42. Considering the soluble ash to be potassium carbon- 

 ate, the 75 cc would equal 0.518 gram of potassium carbonate. The 

 average percentage of soluble ash is 0.62, which is 0.11 gram higher 

 than that calculated from the alkalinity. This may be accounted 

 for by the presence of alkaline salts other than potash. 



LEAD NUMBER. 



The average lead numbers for the individual States vary to a 

 great extent, as shown in Table XVII:
