Browning's Spectroscope

Abstract

A LETTER from Mr. Browning, in the number of NATURE for December 15th, has just come to my notice, and seems to require a word from me. I regret exceedingly that he should have supposed that I intended to imply that he had committed any impropriety in employing in his own automatic combination an arrangement of Mr. Rutherfurd's from a spectroscope which was not automatic. I did not “go out of my way” in making the allusion, but only stated what I supposed to be a fact, in order to show that the proposed arrangement of radial bars was good and practicable, having already been endorsed by most eminent authority.
