Tin has been found in electrolytically refined lead at Trail, B. C., to the extent of 

 O.C2 per cent. No difficulty is experienced in removing this from the lead by poling 

 before casting.

Results of experiments made by combining a small per cent of tin with iron. Of 

 all metals alloyed with iron, experiments point to the fact that tin has the most 

 hurtful effect.

" The final slags produced in smelting of tin ores in the reverberatory furnace cannot, 

 as a rule, be brought to lower content of tin than about 4 per cent, which in works 

 smelting ten tons of ore daily, represents a loss of 3 cwt. to 4 cwt. of metallic tin. 

 Author finds that this may be recovered to a great extent by decomposing the slag 

 with sulphuric acid, when the iron and tin are dissolved, giving a solution from 

 which the latter metal may be recovered by electrolysis."
