“On the Action of Water and Saline Solutions upon 
Lead,” part II., by M. M. Pattison Muie, F.R.S.E., Assistant 
Lecturer on Chemistry, Owens College. 
1. I have already in several places* described the results 
of various series of experiments, undertaken with a view 
to arrive at definite measurements of the solvent action of 
dilute saline solution upon lead, and to ascertain the circum- 
stances which condition this action. The general results 
of these experiments may be summed up briefly as follows. 
(1) Nitrates cause water to exert a very marked solvent 
action upon lead. 
(2) Carbonates, Sulphates, and Chlorides greatly dimi- 
nish the solvent action of water upon lead. 
(3) These three salts, along with Nitrates, greatly de- 
crease or even stop the solvent action exercised by the 
Nitrates when present alone. 
(4) The amount of lead increases with the length of time 
during which the water remains in contact with the lead.
