See A. D. Atkinson, 'Dr Johnson and Newton's "Opticks"' in The Review of English Studies, New Series,II (1951), pp. 226-37; C. S. Emden, 'Dr Johnson and Imagery', in R.E.S., New Series, I (1950), p. 30; and W. K. Wimsatt, Philosophic Words: A Study of Style and Meaning, in the 'Rambler' and 'Dictionary' of Samuel Johnson (1948). Wimsatt traces the growth of scientific vocabulary from Bacon to Johnson and studies its effect on prose style. He demonstrates that Johnson collected specimens for his Dictionary from all the major scientific writers.
