The seaman's daily assistant being a short, easy, and plain method of keeping a journal at sea : In which are contained, rules shewing how the allowances for Leeway, variation, heave of the sea, set of currents, &c. are to be made, and to correct the dead-reckoning by an observation, in all cases: and also all the tables that are any ways necessary for the seaman's use in keeping a journal. By Thomas Haselden, late teacher of the mathematics in the Royal Navy.
