The Assistant Secretary.—In the discussion on Mr. Niecks's paper read in March, on “The Sharp, Flat, and Natural,” reference was made to the absence of a single sign to indicate a double flat, such as is used in the case of a double sharp. I have been asked to bring under the notice of the members of this Association two signs with that object, which have been invented by Mr. Ross, of Messrs. Novello's printing establishment, through whose hands our “Proceedings” pass when in course of publication. A very great deal of music being now printed from type, it is found that the double sign at present in use occupies so much space as to interfere with the symmetrical appearance of the music when thus set up, and Mr. Ross was therefore led to devise some sign which should obviate this disadvantage. The two signs which he has produced achieve this object, and in presenting them to you for your opinion, Mr. Ross hopes that approval from distinguished authority may lead to the general adoption of one or other of them. It is, of course, desirable that any new sign, in order to gain ready acceptance, should present to the eye some resemblance to the present double flat, and thus suggest that the note must be lowered from its normal position. It will be noticed that both signs fulfil this requirement The following passages show first of all the present double sign and then the two signs invented by Mr. Ross.
