“ On the Action of Water and Dilute Saline Solutions 
upon Lead.” — Addendum to Part III. — By M. M. Pattison 
Mum, F.R.S.E., Assistant Lecturer on Chemistry, the 
Owens College. 
In a paper read to the Society (Proc. xvi., 142) I recorded 
the results of a few experiments upon the effect of rolling 
sheet lead as tending to alter the solvent action of dilute 
saline solutions upon such lead. I have now to supplement 
these experiments by others of a similar description. The 
results are tabulated below.
