The reproduction of photomicrographs in this journal is limited by the available space on the page.
The column width is 4¼ inches. All cuts have a ⅛ inch shoulder on each side to permit of the metal being fastened to the wood block; hence, if consistent with the material to be shown, illustrations are reduced to column width—that is, to 4 inches. Larger cuts not only cost more but necessitate additional expense in arranging makeup. When necessary or especially desirable, larger reproductions can be produced, but only in very exceptional instances are cuts made more than 5½2 inches wide.
When photomicrographs more than 5½ inches wide are submitted, authors should decide whether they prefer to have only the significant portion of the illustration reproduced full size or to have the entire picture shown with reduction. Notation of the choice should accompany the manuscript; in case choice is not indicated, manuscript
