NOTICE TO AUTHORS. 
Authors of Papers are urgently requested to send in 
all Drawings, Diagrams, or other Illustrations, in a state 
suitable for direct photographic reproduction. They should | 
be drawn on a large scale, in Indian ink, on a smooth 
white surface, with lettering adapted to a reduction in 
scale. Where illustrations are numerous, much time 
would be saved if authors would indicate in advance 
those considered essential to the understanding of their 
papers. | 
(When the MS. is typewritten the copy should be carefully 
corrected by the author before it is presented.)
