of the extra expense, for additional pages. This expense will be that of typesetting only, which 
is about $2.00 per page. The actual cost of preparing cuts for all illustrations must be borne by 
contributors; the expense for full page plates from line drawings is approximately $5.00 each, 
and for full page half-tones, $7.50 each; smaller sizes in proportion. 
AUTHOR’S SEPARATES 
Reprints of articles may be secured by authors, if they are ordered before, or at the time 
proofs are received for corrections. The cost of these will be furnished by the Editor on appli- 
cation.
