maris tumor.” “In the bend of the sea called Hudson’s Bay, where Hudson passed the winter, the tide of the sea did not rise more than two feet, which also was observed by Thomas James in the year 1631[16] in the Bay called James his Bay where the rise of the sea likewise did not exceed two feet.” Near the last-quoted legend we find, “Thomas Button hibernans in portu Nelson ad altitudinem grad. 57 observavit singulis ex horis aestum maris accrescere 15 pedes aut ultra, qui flante Zephiro solito magis instar plenilunii intumescebat. Sequenti aestate animadvertit quoque ad altitudinem grad. 60 similes aestus maris qui nunc orientem versus nunc occidentem vergebant.” “Thomas Button,[17] who passed the winter in Port Nelson, at the high latitude of 57 degrees, observed hour by hour the tide of the sea to rise 15 feet or more, which tide, with the accustomed wind blowing, swelled very like a (spring) tide. Next summer he noticed at a latitude of 60 degrees similar ocean tides which now had an eastward flow and now a westward.” A legend has been added relating to the magnetic poles and to the difficulty of locating the same, reading “Duos in hoc loco Gerardus Mercator et alii eundem secuti posuerunt Polos magnetis, unum respectu insularum capitis viridis, alterum respectu insulae Corvi et Floridis: cum vero de his nihil certi sit, et quotidiana experientia nos aliter doceat de deviatione acus nauticae ambos omissimus.” “Gerard Mercator and others following him have placed two magnetic poles in this locality, one according to the direction indicated (by the compass needle) at the Cape Verde Islands, the other according to the direction indicated at the Islands of Corvus and Flores: but as nothing is known for a certainty concerning these, and a daily experience teaches us otherwise concerning the variation of the magnetic needle, we have omitted both poles.”[18] The globes of this edition were supplied with the usual brass meridian circles, wooden horizon circles, on the surface of which was pasted the printed representation of the zodiacal signs, the names of the months, and of the principal winds or directions.
