At the meeting of this Society held in November of 1859, there was presented, from Samuel T. Snow, a copper-plate engraving of the Declaration of Independence by an unknown artist; together with the 00pper-plate its-elf. 1 The plate was done in the stipple manner and was unfinished. After a few impressions were struck off, it was placed in the repository of the Society, where it has since remained. Researches made by me during the past few years have resulted in ascertaining just what this picture was, and who was the unknown artist who engraved the copper-plate presented by Mr. Snow well on to half a century ago.
