The strange and dangerous voyage of Captaine Thomas Iames, in his intended discouery of the Northwest Passage into the South Sea VVherein the miseries indured both going, wintering, returning; and the rarities obserued, both philosophicall and mathematicall, are related in this iournall of it. Published by his Maiesties command. To which are added, a plat or card for the sayling in those seas. Diuers little tables of the author's, of the variation of the compasse, &c. VVith an appendix concerning longitude, by Master Henry Gellibrand astronomy reader of Gresham Colledge in London. And an aduise concerning the philosophy of these late discouereyes, by W.W.

Iuly 13^th. 1631.

These 13. Azimuths with the Altitu. Dec. were taken vpon a great piece of Ice, with three Needles together: then the Declination was not equated, the last three set foorth by themselues, prooues the rest: viz. the Azimuth of West with his variation: the Azimuth at due West, And the va∣riation by the Altitude and Azimuth at due West.

These were taken twentie leagues to the Eastward of Sa∣lisbury Iland; and 2. quad. one of 4. another of 2. foote Semid. Semicircle of 2. foote Semid.
