April 8, 1947 Dr. M. Demerec Long Island Biological Association Cold Spring Harbor, Long Island Dear Doctor Denereos I should propose as a title of my paper, “On the Nucleoproteing of Microorganisms." I do not know whether the nucleic acide of bacteria will be dealt with by other speakers, If not, the title could be expanded to read, "On the Nucleoproteing and Nucleic Acids of Microorganiems." I have been invited to speak at the Cytology Congress jn Stockholm and have veen able to secure reserva- tion on a ship leaving June 20th. I, therefore, should be obliged if it were possible to schedule my paper in Cold Spring Harbor sometime before June 17th or 18th. 2 do not know yet whether I shall be able to attend the session from June llth to June 18th but should like very much to do so and should like to inquire whether in thie caso 4% would be possible to bring Mre. Chargaff and my little boy along. With best regards, Sincerely yours, x. Chargaff er To participants in the Symposium on Nucleic Acids and Nucleoproteinss: I assume that you are aware that Volume XI of the Symposia is not yet out. This is because the printing situation, with regard to labor and paper, is very critical, and the work of printing is making slow progress. Volume XI is now past page proof, and should be out within the next few weeks. - We are fortunate in being able to acquire paper for the next volume, which will contain your contribution. The printer is willing to undertake the printing of the volume, with the assurance of speedy work, only if the complete manuscript is in their hands during the summer, which is their slack peried. Therefore we have promised to send the manuscripts to the printer in July. In order that the manuscripts may be edited and prepared for the printer, it is essential that we receive the bulk of them by June 1, and all not later than the beginning of the meetings. I sincerely hope that you will cooperate with us in this. ‘ . - Sincerely yours, LWU Perreau 4 M. Demereo Cold Spring Harbor ~ . - April 25, 1947 anh Ka Notice to Participants in the Cold Spring Harbor Symposia on Quantitative Biology Copy: Manuscripts should be submitted ready for publication, typewritten double-spaced throughout (including References and legends), with one-inch mar-. _ gins. Corrections to the typescript should be typewritten or written legibly in ink; pages should be retyped if they contain extensive corrections. Tabular matter should be typed on separate sheets. All manuscript pages should be nun- bered in order. Authors are requested to indicate in ink on the margin of the copy the approximate place where each table or figure should be inserted. In the text, tables and figures should always be referred to by number (e.gs5 "“Tadle 2," "Fig. 2"), not as "the following figure," sinee it is obviously not always possible to insert them at the precise place requested. Style; Manuscripts should be consistent in style; i.e., a word should not be abbreviated on one page and written out on another, nor temperature given in Fahrenheit degrees in one place and Centigrade in another. Cooperation in making manuscripts as consistent as possible will greatly reduce editorial labor and the cost of alterations in proof. Spelling should follow Webster's New International Dictionary (1936) and, for scientifie terms, Biological Abstracts. For economy, except in unusual circumstences, abbreviations such as %, CMs, CCes ml., ° C.» and Fig. should be used rather than the words for which they stand. For reasons of economy and appearance, genus and species names should be itali- cized (underlined) only when they occur together. not when used separately. Main headings in the text are printed in caps and small caps, and centered; subheadings are in italic (underlined), with all important words capitalitced, -and centered; still smaller subdivisions are represented by paragraph headings, in italic, with only the first letter capitalized, followed by a period. Both figures and tables are referred to by arabic numerals (Fig. 1; Table 1). References: Literature citations should be listed, alphabetically by author, at the end of the article under the heading "References," and referred to in the text by name of author and year of publication, in parentheses. Each citation should give author(s), year, title, journal, volume number, and first and last page numbers--arranged and punctuated as in the examples below. Abbreviations of names of journals should follow the system used in the World List of Scienti- fic Periodicals (Oxford University Press, 1934). No part of the citation should be underlined, except genus and species names occurring together in a title. Examples: (articles) Metz, C. W., and Boche, R. D., 1939. Observations on the mechanism of induced chromosome rearrangements in Sciara. Proc. Nat. Acad. Sci. 25: 280-284. (books) Dobzhansky, Th.> 1941. Genetics and the origin of species. 2nd ed. New York: Columbia University Press. Verification of references; References cannot be verified by the copy-reader or printer. Since references are useless unless correct, authors are urged to verify every reference against the source after it has been transcribed, so that {t may be complete and correct in each detail--spelling (especially of proper names and foreign titles), journal, date, volume number, page numbers, punctua- tion, and accent marks. Illustrations: All illustrations, especially photographs, should be sharp, clear, and submitted ready for reproduction--i.e., with professional lettering, mounting, and arrangements of figures completed. Authar's name and the figure number should be written on the back of each. Whenever possible, drawings should be made with pen and undiluted India ink}; and photographs should be 5. -2< glossy prints with strong contrasts. Line drawings are reproduced on text pages; make the size and proportions of these figures suitable for reduction to the width of a single column (3 inches) or the full width of the type page (6-1/4 inches). Indicate the amount of reduction desired. Plates are used for photographs, which require inserts of special paper, or for collections of small figures that cannot be designated conveniently as separate figures. TIllustra- tions arranged as plates should be trimmed and mounted close together on heavy white cardboard; unless the edges are straight and fitted perfectly together, the cost of reproduction is greatly increased, All illustrations, whether graphs, drawings, or photographs, are referred to as figures, and should be numbered consecutively from 1 up--regardless of whether they are to be text figures, plates, or parts of plates. Figure numbers should not appear as part of the figure in drawings; but in plates that consist of a collection of figures, each figure should be clearly numbered (arabic numerals). In plates that repre- sent one figure with several different parts, the parts should be lettered a» bs. c, etc. (lower-case letters). Illustrations should be reduced as much as possi- ble without sacrificing necessary detail. If an illustration is taken from a paper already published, the source should be given in full, as in some cases the publisher will have to ask permission for reproduction. Legends for figures should be typed on a separate sheet. (Captions of tables, however; should be typed on, the. same sheet as the table.) . : Footnotes should be avoided whenever possible. Usually, the material can be enclosed in. parentheses and inserted after the sentences to which it applies. If footnotes are used, they should be numbered consecutively in a single series, designated by arabic superscript numerals, and typed on a separate sheet. Proof: Galley proofs and, whenever there is time, page- proofs will be sent to authors, who should leave forwarding directions when they are to be away from the address sent with the manuscript. Ordinarily,» page proofs cannot be sent out of the country. Both sets of proof must be returned promptly; and no exten- sive change may be made on page proof which is not compensated for within the ~ > same paragraph or in an adjacent paragraph on the same page. Changes from copy in either set of proof will be charged to the author. | oO Reprints are supplied at cost, and should be ordered when galley proof is returned.
