[Letters to Editor]

Abstract

I SHALL be very pleased to send Dr. Muir a copy of my father's examination questions of June, 1873, containing the word radian; and when Dr. Muir returns to England I should like to show him my father's copy of the “Imperial Dictionary” containing a note in his own hand saying that he had proposed the word in July, 1871. So far as I know, he did not meet Dr. Muir until he came to Glasgow in October, 1873.
