Abstract
I GREATLY regret that in a note of mine on a “new mode of using the concave diffraction grating,” in the “Astronomical Column” of March 22 (p. 501), I wrongly interpreted a sentence of Prof Rizzo's article, which led me to think it was inconvenient for him to use the instrument in the usual way. The words “Dr Rizzo investigated this disposition on account of being unable to use the instrument as usually set up,” should therefore not have been included.
