By Benjamin Workman. The extensive eclipse predictions are almost identical in wording with those in the Pennsylvania, Delaware, Maryland and Virginia almanack for 1790 (Baltimore), calculated by Workman. The majority of the astronomical notes on the calendar pages, and the times of the moon's rising and setting, are also identical. The other calculations vary slightly for the most part, reflecting the difference in meridian between Baltimore and Philadelphia.
Advertised in the Freeman's journal, Philadelphia, Dec. 9, 1789.
