Iune 21. 1665. mr, Hooke produced a sextant diuised by himself & explaind the structure & vse thereof vizt that it was
made after the manner of a pair of Diuiding compasses, there being 2 threefoot tubes opening vpon a joynt in the
manner of the leggs of compasses and a long streight screw mouing in two motions seruing to take angles very ex
-actly. It was moued by Sr P neile that this Instrument might be examined to see whether it performes what it is intended
for by measuring some known distances wth. it, and it was orderd therevpon that this should be done.
mr Hooke produced some curiositys addressed to him by one mr. wim: Iumper. vizt certaine tongues, teeth, & Eyes, called

perpendicular downwards because that the Descent of an expanded Area perpendicular do moued edgways
horizontally in the air was extreamly differin in which way yet all motion of flying must be performed
Dr. wren being desired to Leaue what he had done about the Late comets promised to doe soe. the same suggested
that an Expt. might be made whether the point of a magnetick needle being sharpned with all exactnesse
imaginable, the needle would Return to the same point himself hauing found that it would not.
