446 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS (2) S. Rothman, Physiology and Biochemistry ot the Skin, The University Chicago Press, Chicago, Ill., 1954, Pp. 494-560. References to books containing contributions from numerous authors appear as follows: (4) s. D. Gershon, M. A. Goldberg, and M. M. Rieger, Permanent Waving, in M. S. Balsam and E. Sagarin, Cosmeticss Science and Technology, vol. 2, 2nd ed., Wiley Interscience, New York, N.Y., 1972, Pp. 167-250. (d) Abbreviations: The metric system should be used. In accordance with modern practice, abbreviations such as mc, sec, rpm, ml, and mg are used without periods. It is requested that authors avoid all unusual notations, i.e., milligram per cent (mg %) or ppm mg/100 g and mg/kg are more acceptable terminology. Prefixes before names or organic compounds must be italicized (cis-, p-, tert-, etc.). (e) Trade Names: A trade name must be followed by the sign "©." All common cosmetic ingredients should be referred to by the name indi- cated in the latest edition of CTFA Cosmetic Ingredient Dictionary, The United States Pharmacopeia (U.S.P.) and the National Formulary (N.F.) including specific manufacturer's designation as a footnote. If a material is not listed then the proprietory or trademarked name can be used with the chemical composition and the name and address of the manufacturer given in a footnote. (f) Structural Formulas: Structural formulas should be used only if abso- lutely necessary and if the chemical in question is not well known to the reader. Structural formulas should be numbered and referred to in the text by Roman numerals. (g) Tables: Tables should be numbered consecutively, using Roman num- erals. Tables should include appropriate captions. (h) Figures: Photographs and drawings (including graphs) are figures and are numbered consecutively using Arabic numbers (e.g., Fig. 3). On the back of each, the figure number, title of paper, author's name, and top of figure should be indicated. Captions should be typed, double-spaced, on a separate sheet of paper. All drawings should be prepared on plain white tracing paper using In- dia ink or standard tapes. The size should not exceed approximately 210 mm x 297 mm (8•/•" x 11") and it is preferable that hhe original copy be submitted although glossy photographs are acceptable. All numbers and letters must be sufficiently large on the original to make the smallest characters legible after reduction to print size. Let- tering of coordinates is part of the drawings and should not be set in type. A TYPEWRITER MUST NOT BE USED BECAUSE TYPING DOES NOT GIVE THE CLEAN, SHARP FIGURE NECESSARY FOR GOOD REPRODUCTION. All information and notations placed

Galley Proof-Galley proofs will be sent to the authors for careful rereview and correction. Proofs should be verified against the manuscript. The Pub- lication Committee will not accept this responsibility. Alterations in an article after it has been set in type are made at the author's expense, and it is understood that any such alterations shall be charged to the author, be paid for by the author. Any material set in type but ordered withdrawn from publication must also be paid for by the author. 6. Reprints-The senior author of each paper will automatically receive 50 over-rnn reprints free of charge. Additional reprints must be ordered at the time the galley proofs are returned and are charged to the author. An order blank for this purpose is sent to the author along with the galley proof and must be returned when the galley is returned. 7. Rejection of Papers Submitted-Manuscripts not prepared in accordance with these directions or deemed to be outside the scope of articles pub- lished in the Journal will be ret•rned to the author by the Editor. 8. Page changes-Effective with the February, 1977 issue the authors of a manuscript published in this Journal will be assessed a page charge of $25 per printed page. These charges are invoiced to the Senior Author at the time the manuscript is published.
