STANDARD SIZES FOR ILLUSTRATIONS 



IN THE JOURNALS PUBLISHED BY 



THE WISTAR INSTITUTE OF ANATOMY AND BIOLOGY 



SUGGESTED BY PROFESSOR SIMON HENRY GAGE 



AND APPROVED BY THE ADVISORY BOARD OP THE WISTAR INSTITUTE AT ITS LAST MEETING 



(APRIL 1910) 



STANDARD MAGNIFICATIONS 



It is desirable that a uniform system of magnifications should be 

 followed in making illustrations for publication. 



This system has been adopted: 1, 2\, 5, 10, 15, 20, 25, 30, 35, 4.0, 45, 

 50, 60, 70, 75, 80, P0, 100, 125, 150, 175, 200, 250, 300, 350, 400, 450, 

 500, 600, 700, 800, 900, 1000, 1250, 1500, 2000. 



Authors are requested to make their drawings of such size that when 

 reduced for publication the magnification will correspond exactly with 

 one of the numbers of this system. 



The relative size of every published figure should be given thus: 

 State whether it is (1) of the same size as the object; (2) magnified, 



as indicated above; or (3) smaller than the object, as Jr, i, j l , etc. natural 



size. 



DRAWINGS AND THEIR REDUCTIONS 



1. If there is to be no change in size by the engraving process, the 

 drawing must be of the same size as the finished engraving. 



2. If the drawing is to be reduced f, then it must be twice the size 

 of the engraving, (i.e., every line in the drawing must be twice the length 

 it will appear in the engraving — twice the diameter). 



3. If the drawing is to be reduced f, it must be made If times the 

 size of the engraving. 



4. If the drawing is to be reduced \, it must be made 1| times the 

 size of the engraving. 



Examples. Suppose the illustration (as it will appear in one of the 

 journals) is to be at a magnification of 40. The size of the drawing for 

 each of the above would then be as follows: 



(1) Full size, or no reduction — each line of the drawing must lie 40 



times the length of the corresponding line in the object. 



(2) For | reduction- — each line must be 80 times the length of the 



corresponding line of the object. 



(3) For I reduction — each line must be 60 times the length of the 



corresponding line of the object. 



(4) For I reduction — each line must be 50 times the length of the 



corresponding line of the object. 



HOW TO MARK A DRAWING TO BE REPRODUCED. 



(1) Full size (i.e., no reduction), (2) \ off; (3) | off; (4) \ off; (5) \ off.
