1 This column may be taken as representing, nearly enough, correct weights of white arsenic for the low- 

 strength bath. 



2 This column represents correct weights of white arsenic for the high-strength bath. 



The method by volume. — This method naturally applies only to 

 the use of stock solutions, not to cases where the desired amount of 

 white arsenic is to be weighed out and dissolved on the spot. The 

 facts needed to start on are exactly the same in both methods; that 

 is, one must know the capacity of the vat at the full water line, the 

 amount of bath actually in the vat, and its strength expressed as 

 per cent of actual arsenious oxid. The problem really resolves itself 

 into correcting the strength of the bath already in the vat, for when 

 this has been done it is simply necessary to fill up the remaining 

 space in the vat with bath of the regular strength. Calculations are 

 simplified by the use of Table 2. 



Table 2. — Amount of arsenic stock necessary to correct each 100 gallons hath. 



1 A bath less than half the desired strength should be discarded entirely
