apparently been dissolved out. The sheet is much corroded, and 
very thin on the edge, stained green and brown. 
Heated in a tube it emits a.“ sea-shore” odour, and gives off 
water which has an acid reaction ; it also yields a fusible subli- 
mate of tarry matter mixed with sulphur. Dissolves entirely in 
nitric acid, one to three water. The metal when boiled with 
water, yields a solution containing chlorine and a trace of sulphuric 
acid from sulphates. After boiling with pure dilute sulphuric 
acid, the metal acquires a copper-red colour and shows a granular 
or crystalline structure ; a black residue is left, and the solution, 
on cooling, deposits crystals of lead chloride.
