The Omission of Titles of Addresses on Scientific Subjects

I VENTURE to ask the attention of ``whom it may concern'' to the practice in vogue in Great Britain of publishing presidential addresses of scientific societies and of sections of the British Association without any mention of the titles of those addresses. Take, for example, a case quite at random, but just at hand. NATURE of August 17, beginning on p. 368, contains the inaugural address of the president of the British Association with the heading ``Part I.'' On p. 372 of the same number is another presidential address without a title. On p. 378 a third address has no general head, but it has the distinct advantage of four subheads that enable the reader to select at a glance what he wants, and to pass over other matters if he so chooses.
