a pure brine for each degree of the salinometer, the number of 

 grains of salt to the wine pint of 36,625 cubic inches, and the num- 

 ber of gallons of such brine required to yield a bushel of salt 

 weighing 56 pounds. 



" From this table the properties and capabilities of any brine may 

 be ascertained by knowing its strength as shown by the salinome- 

 ter. Suppose, for instance, the salinometer shows 53°. The table 

 shows at a glance that this corresponds to 13.78° of Baume's hy- 

 drometer, a specific gravity of i.ioo, and a percentage of 13.62 ; 

 while a wine pint of the brine would furnish 1092 grains of a solid 

 residue, and 44.7 gallons would produce a bushel. 



" If the strength of a brine is expressed by giving its specific grav- 

 ity, and we wish to compare the strength as thus stated with that of 

 another brine given in degrees of the salinometer, or the number of 

 grains in a pint, and we look in the column of * specific gravity' in 

 the foregoing table, and find the number which agrees nearest with 

 the given one, then on the same horizontal we have all the synony- 

 mous expressions for the same strength, and it is seen at once 

 whether the brine with which we wish to make the comparison is 

 stronger or weaker. 



" Or suppose, thirdly, that a land-owner desires to know the com- 

 parative strength of a brine spring on his premises, while he pos- 

 sesses no instrument for taking specific gravity. Let him evaporate 

 a wine pint and weigh the residue, or take it to the apothecary to 

 Aveigh ; then the number of grains found in the fifth column of the 

 table will show him all the equivalent expressions.
