Quia in his Experimentis non accurate videre poſſumus diſtantias
Magnetis ab acu; juſſit Societas Regia, ut Nob. Brook Taylor caperet
experimenta alio & clariori modo de viribus Magnetis, adeoque hic
ſubtilis egregiuſque Mathematicus poſuit acum in centro Quadrantis
prioris, & Magnetem, cujus axis in plano horizontali jacebat, admovit
removitque ab Acu in linea recta, quæ cum naturali directione Acus
faceret angulum rectum: tunc diſtantias menſurans perlineam inter
centrum & Magnetem interjacentem; condidit ſequentem tabulam.

Hæc Experimenta facta ſunt cum Magnete præſtantiſſimo Socie-
tatis Regiæ; ſed quoniam in hiſce non obſervata fuit ſimilis poſitio
Lineæ, in qua movebatur Magnes verſus acum, quod erat admo-
dum neceſſarium, non multum ex his concludi poterat, obſervante
Whiſtono, qui idcirco alia experimenta de novo inſtituit: imo ar-
bitror hiſce methodis nos voti compotes fieri non poſſe, uti pate-
bit ex ſcrupulo, quem in medium proferam, poſtquam Whiſtoni ob-
ſervationes annotavero. Operæ pretium autem eſſe indicavi
