VII. On the means of discovering the distance, magnitude, &c. of the fixed stars, in consequence of the diminution of the velocity of their light, in case such a diminution should be found to take place in any of them, and such other data should be procured from observations, as would be farther necessary for that purpose. By the Rev. John Michell, B.D. F.R.S. In a letter to Henry Cavendish, Esq. F.R.S. and A.S

Dear Sir, The method, which I mentioned to you when I was last in London, by which it might perhaps be possible to ind the distance, magnitude, and weight of some of the fixed stars, by means of the diminution of the velocity of their light, occurred to me soon after i wrote what is mentioned by Dr. Priestley in his History of optics, concerning the diminution of the velocity of light in consequence of the attraction of the sun; but the extreme...
