Transcription
There were made some more Experiments, to find, what is the resistance of the Air to Bodies moved through it with several Velocities, which was at this time done with several weigths fastned to the same Area of a thin latton-plate.
NB The result of the single weight was not observ'd by the Secretary.
The double weight being fastned to the PLate, the vibrations of the whole were after this manner:
The Treble weigth being fastned to the same Plate, the Vibrations went thus:
The Quadruple weight being fastned still to the same Plate, the Vibrations went thus:
It was ordered that these Experiments should be varied the next day, by applying the same weight to several Areas, as now they were tryed by applying several weights to the same Area.

Object history
At the meeting of the Royal Society on 4 March 1669, ‘Some more experiments were made, to find what is the resistance of the air to bodies moved through it with several velocities; which was at this time done with several weights fastened to the same area of the thin lattin plate’ (Birch 2:352). The experiment is printed in Birch 2:352-53.
