Abstract

A NEW volume of NATURE will begin with next week's issue, so that in future each of the two volumes published annually will bear the date of a single year. This change has been decided upon for convenience of reference, and we believe it will be generally welcomed. Hitherto reference to a particular year of publication could apply to three different volumes, while the volumes which overlap the end of one year and beginning of another bear the dates of two years. Henceforward the volumes will begin respectively in January and July, and a common source of confusion will thus be avoided. The alteration means that the volume completed with this week's issue extends over four months instead of six, but the new arrangement has such decided advantages that no excuse is necessary in introducing it.
