[7] Dr. Whewell states that Descartes regarded light as "consisting of small particles emitted by the luminous body," but Mr. Vernon Harcourt (Letter to Lord Brougham, p. 32) has shewn the incorrectness of this opinion. See Œuvres de Descartes, tom. vii. pp. 193, 240.

[11] In a paper entitled "Observations," which accompanied this letter, but which was not printed, Newton says that Hooke, in his Micrographia, had "delivered many very excellent things concerning the colours of thin plates, and other natural bodies, which he had not scrupled to make use of as far as they were for his purpose."

[12] In his Optics, published many years after this, in 1704, Newton does not give Hooke the credit of having made these observations.
