Description | Dr Wallis donated his 'Archimedes Arenarus' being a new version of his, with notes theron. Ordered the Doctor be thanked and the book put into the Society's Library; book left with Mr Hook.
' The reading of Mr Newton's Discourse was continued, viz that part wherein he explains by the simplest of colours the more compounded.
Which done occasion was taken to discuours of Mr Newton's Theory itself, and to debate whether the rayes of Light, which though alike incident in the same medium, yet exhibit different Colours, may not reasonably be said to owe that exhibition of different colours to the several degrees of the Velocity of Pulses, rather than (as Mr Newton esteems) to the several connate degrees of refrangibility in the Rayes themselves?
Mr Hook was of the opinion , that the former of these wayes was sufficient to give a good account of the diversity of Colours. ' |
