From these formulas the following table has been calculated :

It is olten desirable to know G in terms of the degreos of Beauma's scale. This valuo

(Seo McCuIlooh, Rep. on Sugar and Hydrometors, p. 71) in which B represents the degrees 

 of Boavmi's hydrometer cxprcssivo of the density of the brine. Substituting this value of 

 g in (6), w.igot 

 677.003 

 C= 4.454 (6) 



Fince 26* Boaumc, or 100° of tho salometer, marks saturated brine, it appears that ono 

 degree of Beaumj equals 3. £46 of the salonutur, or, putting S for the reading of the salometer 

 I%=.26S

 From winch mny be calculated a table giving the numhor of gallons of brine required for 

 ©no bushel of s.iit, at every degree of tho centigrade salometer. 



Although, owing to the inconsistency of the data employed, the foregoing formulae can 

 give only approxiro.it ? results, they may be Bilmcioutly accurate for practical purposes; and 

 nenco a tablu bus been based upon them.
