tables show: (a) the accurate quantities of solids to be dis- 
solved in sufficient liquid to make a total bulk of 100 parts for 
the various percentages; (b) the number of grains to be dis- 
solved in sufficient solvent to make 1 ounce of any given 
percentage. |

These tables are sufficient to calculate any percentage or 
volume, by merely multiplying or adding. Example: Re- 
quired to make a 15 per cent solution, how many grains are 
required :
