Vol. VI. 



APRIL, 1881. 



No. 4. 



Editorial. — ^Vith this issue we publish the first of several papers 

 by Dr. J. T. Rothrock upon the Modes of Work in de Bary's Laboratory 

 at Strassburg That they will be read with interest by our workers in 

 Anatomy and Physiology is but natural; for they will be a description 

 of one of the most famous laboratories in the world, by one of our 

 most skillful investigators. 



Dr. Asa Gray, in a private letter from Kew Gardens, assures us 

 that he is not resting from labor, but is busier than ever. With the 

 change of a word, he uses the old quotation, cmlum fion laborem mu- 

 tant qui trans man ciirrunt. 



Contributors must exercise some patience in waiting for the ap- 

 pearance of their articles. The Gazette is getting to be quite popu- 

 lar and no contributor can now be certain of an immediate place in 

 our pages. If, then, two or three months pass without a sign from us 

 no alarm need be felt, for everything will be worked in in its own time, 

 and the appearance will condone for much delay. This is not meant 

 to stop the flow of contributions, for we would like it to be steadier 

 and stronger than it is now, but as a word of explanation to many of 

 our friends who may by this time have lost all patience with us. 



Mr. H. H. Rusby's article on the Ferns of New Mexico has been 

 sent to us through the kindness of the Syracuse Botanical Club, Mrs. 

 F. J. Myers, Secretary. This organization of ladies is unwearying in 

 study and exploration. 



Mr. Lucien M. Underwood, of Bloomington, 111., has published 

 a neat check list of North American Pteridophyta, excluding the 

 Orders Filices and Op/iioglossacece. Order Equisetacecc contains 13 

 species; Lycopodiacca. \2 \ Sclai::;inellacca 6 ; Isoetacece 14; Marsilia- 

 cecc (three genera) 7. The author states that the list is merely pre- 

 liminary and that he will be glad to receive specimens and notes, that 

 a full account of native Pteridophyta may be prepared. 



Prof. Marcus E. Jones, of Salt Lake City, Utah, has published 

 his list of Utah plants. Prof. Jones is an indefatigable collector and 

 his plants are very desirable. The coming season he will botanize 

 through Utah, Nevada, California and Arizona. 



Prof. W. G. Farlow has just published a paper, with plates, upon 

 the Gymnosporangia or Cedar-Apples of the U. S. An early review 

 of it may be expected in the Gazette. 



In the last part of the second volume of Beitrage zur Biologic der 

 Pflanzen are some important papers on fungi and Bacteria, and one on 

 {)hysiology. Dr. Just has been experimenting on the action of high 

 temperatures on the preservation and germination of seeds. He finds 

 that perfectly dry seeds can withstand a temperature of even 120°
