Editorial

We regret to announce that due to the necessity of economising paper we have had to curtail publication of two issues again this year. We are therefore extremely grateful to the Institutions whose Transactions and the Librarians, Editors, Managers and Proprietors of those esteemed periodicals which we have received for display in our Association's free reading room and Library in spite of our inability to present any publication in exchange. We assure them of our intention to make good this exchange at the earliest opportunity after the conclusion of the war.
