Rough sketch of a candle wick and flame, inverted. This is associated with an experiment demonstrated at the Royal Society meeting on 16 January 1679, intending to show that the air directly encompassing a candle flame exhibited different properties from the air further away. The image is partially drawn over Robert Hooke's draft minutes of the meeting, now bound into the 'Hooke folio' (MS/847).


Mr Hooke shewed also a second experiment which was the flame of a Candle soe placed between the eye and a concaue metalline speculum, that the Air which incompassed the said flame and which by Dissoluing the parts of it into its self became of a differing nature and differing refraction from that which was not satiated by the said Dissoluing. This was plainly seen by the President and Diuers others of the member [sic] present. to their satisfaction.
