Wingate's rule of proportion, in arithmetick and geometry: or, Gunter's line newly rectified

by Mr. Brown and Mr. Atkinson, teachers of the mathematicks. Fitted for all artists for measuring and building. Whereinto is now also inserted the construction of the same rule, and a farther use thereof, in questions that concern astronomy, dialling, geography, navigation, gaging of vessel, military orders, interest and annuities.
