A number of somewhat considerablerust warts of varying colour and thickness were formed. Inthis case in particular the photographs afford a decided proofof the damage that may be occasioned to iron by the actionof atmospheric influences, and it is really incomprehensiblethat iron articles should be — as they frequently are — leftlying exposed to the open air for weeks and months withoutany protection.
