fame quantity of real acid as loo grains fp. fait whofe fp, gr. is 



And ioo grains nitrous acid 1,1963 contains the fame quantity 

 of real acid as 100 grains fpirit of fait whofe fp. grav. is 1,187. 



Hence it ftiould feem that the fp. grav. of the real marine acid 

 is fmaller than that of the real nitrous, and that of the real nitrous 

 fmaller than that of the real vitriolic, fince when the weight of 

 each acid, and alio the weight of real acid in each is equal, the vi- 

 triolic acid is fpecifically heavier than the nitrous, and the nitrous 

 than the marine, but this perhaps may arife from penetration. 



Problem 10. 



To find how much of a neutral fait of one fort holds as much 

 real acid or bafis as a given weight of ihe Jame neutral fait in 

 another ftate, or as a given weight of another fait in any given 

 flate. 



These queftions are refolved by the 4th ^nd 5th tables, thus 



if it be a&ed, how much nitre contains as much acid as 20 grains 



of vitriolated tartarin? By the 4th table I fee that 221,48 parts of 



vitriolated tartarin and 227,22 parts nitre contain equal quantities 



of acid fince both contain 100 parts, then as 221,48. 227,22 : :
