12. But when mixed together the insoluble arsenic is formed as 
fast as soluble arsenic goes into solution. 
13. That after white arsenic has stood for a time in water, the 
mixture should not be applied to foliage without first adding lime. 
14. That Bordeaux mixture prevents the solubility of the arsenites 
and their injury to foliage by virtue of its lime. 
15. That the arsenites are more soluble in simple solutions of 
sulphate of copper, sulphate of iron, and chloride of iron than in 
water, and injure foliage more than when applied in water. 
16. That the arsenites are very soluble in Eau Celeste and Eau 
Celeste modified with soda mixtures, and do very great damage to 
foliage when applied in them. 
17. That the kerosene emulsion is not a favorable medium for 
applying the arsenites. 
Note.— To prevent lime from becoming lumpy when added to mixtures, it 
should be slaked in a small volume of water and all the lumps well broken.
