This paper is. intended to give a preliminary account of some recent investigations into the specific refraction of the elements. It may be conveniently divided into two distinct parts. The first part is a revision and extension of the list of specific and atomic refractions, which was first published in the ‘ Phil. Trans.’ for 1870, and was reprinted with modifications in a lecture given at the Royal Institution in 1877. The second part is an amplification of some deductions made in that lecture.
