name and description neatly pasted upon them. Kach species paper 

 has the generic initial and the specific name and description pasted 

 upon it. This method virtually converts my herbarium into an in- 

 valuable illustrated Gray's Manual, and in my opinion is more handy 

 than it would have been had I adopted the methods currently 

 advocated. — \V\i. K. Andrews, Blackburn University^ Carlinville, III 



NOTES AND NEWS. 



Mr. E. J. Hill is writing a series of articles for Garden and Forest. 

 on the autumn flora of the Lake Michigan pine-barrens. 



M. W. Beyerin t ck has succeeded in isolating some of the very small 

 algae by a modification of the gelatine-plate process used by bacteriol- 

 ogists. Cf. Bot. Zeit. y 48, 725. 



The Journal de Botanique (Nov. 16), contains an account of the 

 Piperaceez of Ecuador, New Grenada, and Peru, in the collection of 

 M. Ed. Andre, with descriptions of many new species, by ML C. De 

 Candolle. 



M. E. Bourquelot has examined the sugar in a large number of 

 species of Boletus, as well as some Amanitas. He finds the sugar 

 when the plants are young to be almost always trehalose {2.7 — 7.8 per 

 cent.), which is replaced with increasing age by mannite. 



Dr. Thomas Moroni; has returned from his long South American 

 trip, and has been appointed curator of the herbarium of Columbia 

 College. Mr. Morong is to be congratulated upon his successful trip, 

 tnd upon the very congenial and fitting position that he found await- 

 ing his return. 



A very INTERESTING discovery of an arctic plant in Alpine regions, 

 was made last summer by Professor M. A. Carleton, of Garfield Uni- 

 versity, Wichita, Kansas. Douglasia arctica Hook., known only from 

 our northwestern arctic seashores, and poorly known even from that 

 locality, was discovered on Pike's Peak, Colorado. 



Am elevation of temperature of 20 z C, due to growth was observed 

 by H. Devaux ( Bull Sac. Bot. de France, xxxvii, 168) in a pile of stored 

 potatoes that had produced sprouts a foot or so long. 'The surround- 

 ing air indicated 18 to 19 C, the tubers on the outside of the pile 

 1 or 2 degrees higher, and at the center of the pile. 2 meters from the 

 surface, the temperature stood at 39° C. 



M ML SCHLOESING, Jr. and Laurent have shown by a direct method 

 that the Leguminosae can fix free nitrogen. Instead of determining 

 the amount of N in the seed and subsequently the amount in the 

 crop, they measured the N. (), and CO2 introduced into a chamber 

 with growing plants. After three months they again determined thes 

 gases, when the X was found to have diminished. Every precaution 

 seems to have been taken against error.
