342:5- THE AMERICAN NATURALIST. 
and are glad to know that there is so much room for improvement. 
We wish the Kalender every success, and hope to see it a permanent 
institution, and call upon American botanists to see that our botani- 
cal institutions are fully and correctly represented in the edition for 
1900. The book is published by the Borntraegers at Berlin for three 
marks, 
The Beiträge zur Biologie der Pflanzen, published at irregular 
intervals under the editorial care of the late Professor Cohn, of 
Breslau, has been recommenced with Dr. Brefeld as editor. While 
the retention of the original title is entirely commendable, it is to be 
regretted that the new volume should be issued as “ Herausgegeben . 
von Dr. Ferdinand Cohn.” A change in expression, similar to that 
made on the title-page of the J/ahrbiicher fur wissenschafilichen Botanik 
after Professor Pringsheim’s death, would better have expressed the 
facts, while securing the desirable perpetuation of Professor Cohn’s 
name in connection with the journal. 
« Natural Science,” with the initial number of Vol. XIV, the 
first under the new management, makes.its appearance in a new 
dress. The greenish tint of the cover has given way to a grayer 
tone, and the typography of the title-page is somewhat changed. 
The journal is now printed on heavier calendered paper, and is, 
on the whole, improved in appearance. The general makeup is 
unchanged, except for the addition of the new column of “ Fresh 
Facts,” which comprises brief references to facts of interest in 
current literature. We wish our esteemed contemporary a most 
prosperous and happy new year.
