Poor Richard improved: being an almanack and ephemeris ... for the bissextile year, 1748 : ... Fitted to the latitude of forty degrees, and a meridian of near five hours from London; ...
Description
With the almanac for 1748 Benjamin Franklin introduced an important change which he continued in the years that followed: he expanded his pamphlet to thirty-six pages and gave two facing pages to each month. With some minor differences the left-hand one was like the single monthly page of the earlier issues. Part of each right-hand page was given to additional tabular matter and the rest was filled with “literary” material.
