SCIENTIFIC AMERICAN, New York, July 2, 1859  This is the first issue of the new format, or "New Series" as described in the dateline. Was previously a folio-size newspaper. Has news and some illustrations concerning the latest developments in science, agriculture, chemistry and more. First leaf has a bit of minor loss in the blank margin next to the spine and is somewhat worn due to it being the first in the series within a volume - typical.
