Now lately invented, and perfected, explained, commented on, and, with all possible brevity, and perspicuity, in the hiddest, and most re-searched mysteries, from the very first grounds of the science it selfe, proved, and convincingly demonstrated. By Sir Thomas Urquhart of Cromartie Knight. Published for the benefit of those that are mathematically affected.
The sea-mans practice, contayning a fundamentall probleme in navigation, experimentally verified: namely, touching the compasse of the earth and sea, and the quantity of a degree in our English measures. Also, an exact method or forme of keeping a reckoning at sea, in an kinde or manner of sayling. With certaine tables and other rules usefull in navigation. As also in the plotting and surveying of places. The latitude of the principall places in England. The finding of currents at sea; and what allowance is to be given in respect of them. By Richard Norwood, reade of the mathematicks.
