A perpetual and universal almanack [electronic resource] : comprised in a most compendious table, exhibiting with great dexterity, all moveable feasts and terms, with other the common notes in both accounts; the change of the moon, the day of the week corresponding to the day of the month, and the contrary: all which are again indigited by an artifice arithmetical, very feasable to the meanest capacity, and never before published. Together with a large appendix, comprehending the most necessary proposition in astronomy and cosmography; resolv'd as by briefe and generall tables, so by trigonometry; the principall heads of which are inserted in the next following page. / Composed for the benefit of sea-men and travellers, and commended as usefull for all by John Catlett.
