At a recent meeting I accepted a suggestion made by a member of our Council, and agreed to put together a few notes on the trumpet scale, at the time believing that these notes would merely fill up the few minutes that might remain over from the reading of a more important paper. I now find that my few remarks are to provide the whole subject-matter for this evening's meeting, and can only trust that you will accept them rather as suggestions for discussion and exchange of views, than as forming a paper such as those to which you are accustomed.
