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. 

 Where illustrations are numerous, much time would be saved 

 if authors would indicate in advance those considered essen- 

 tial to the understanding of their papers.
