aE) Mc Graw-HiLL Book CoMPAny-INc. Dr. Allen - PAGE two pate 9727-357. In the ease of the diagrams, we sincerely hope that you will confine the descriptive legends to a single line of type because most of the diagrams have been planned to be arranged two to a page. We have made them to the maximum size for this purpose. It is not so important that the descriptive legends for the half tone reproductions be confined to a single line, but we hope that you will make them as brief as possible. The above procedure, at least in so far as is concerned the diagrams, would mean that we would proceed with the page makeup without first submitting proofs of the engravings for your approval, but since the engravings will be photographic reproductions of your tracings, this would not be serious. However, just as soon as we have any engraver's proofs available of the diagrams, we will send you a duplicate set of these by air mail and the proper figure numbers will be found on these proofs. If they are satisfactory you need not bother to return this duplicate set of cut dummies, but if you find anything seriously wrong, we hope that you will wire us immediately. Finally, I am enclosing another copy of our four page Instructions to Authors leaflet, the first page of which contains full and complete instructions about the | proper procedure to be followed in the handling of proofs. - In so far as is concerned the return of proofs, or cor- respondence, please understand that it is necessary only for you to address either proofs or correspondence simply to the production department. It is not at all necessary to address proofs or correspondence to any individual be- cause we are mainly interested in getting our hands on the material. Very truly yours, duction Department. JAH: LOC
