THERE has already been published in this REVIEW an analysis of the seasonal variations in weekly figures for outside bank debits.' In presenting the results of that study a special method for determining and eliminating seasonal variations as they appear in weekly data was developed. The following paragraphs apply that method, in full or in part, to four weekly series; in addition, a revised and improved analysis pertaining to outside bank debits is in course of preparation, and will be presented in a forthcoming issue of this REVIEW.
