A new edition of the Naturalists' Directory has just been 

 published by S. E. Cassino, Salem, Mass. This directory is 

 useful to naturalists since it is the means of bringing together 

 students and collectors in all parts of the world through cor- 

 respondence. The directory contains an alphabetical list of 

 English speaking professional and amateur naturalists in all 

 parts of the world, also a list of scientific societies and periodicals. 

 Further information may be had from the publisher. 



An announcement has just been issued of a new paleobotanical 

 bimonthly, Paleobotanischen Zentralhlatt, which is to be published 

 under the auspices of the Internationalen Paleobotanischen 

 Gesellschaft. It is under the management of a committee, 

 which in America is represented by Dr. E. W. Berry, Johns 

 Hopkins University, where additional information may be 

 obtained.
