Abstract :
Because of increased production costs, many journals have levied page charges. The new policy of this TRANSACTIONS is to make no page charge to the author for articles which do not exceed six TRANSACTIONS pages. A charge of $100.00 per extra page, to be paid by the author or his institution, will be made for articles longer than six pages, total, including figures and appendices. Papers already submitted (as of September 1975) are excepted from the new page charge.
