424 BOTANICAL GAZETTE [june 



Dr. Oskar Brefeld, ha\-ing been compelled by serious trouble with his 

 eyes to give up the editorship of Cohn's Beitrdge zur Biologie der Pflanzen, the 

 duty has been assumed by Professor Feux Rosen" of the University of Breslau. 

 The second and concluding part of the ninth volume has recently appeared after 

 an interval of several years. 



The large and valuable herbarium of the late Mr. A. P, Morgan has 

 been presented to the State University of lovr'a by his widow. It includes his 

 botanical library, and is undoubtedly the most complete collection in existence 

 of the mycologic flora of the lower valley of the Ohio River, and must always 

 remain of importance on account of the numerous tj-pes it contains. 



Theodor Oswald Weigel (Leipzig) has issued the first number of a paper 

 entitled Herbarium^ which will be published bimonthly, and is to be devoted to 

 the distribution of exsiccata. It will announce continuations of current collec- 

 tions, collections that are wanted, and those that are offered. The publisher 

 feels that this handling of dried plants in addition to botanical books will prove 

 of advantage to many botanists and botanical establishments. 



The following summer laboratories, in addition to those already noticed, 

 announce botanical instruction and research: Marine Biological Laboratory, 

 Woods Hole, Mass., July i to August ii (George F. Moore, John M. Coulter, 

 George R. Lymax, C. J. Chamberlain, R. R. Gates, C. H. Shattuck, W. R. 

 Maxon); Biological Laboratory, Cold Spring Harbor, L. L, July i to August it 

 (D. S. Johnson, George D. Fuller, Harlan H. York); Lake Laboratory, 

 Cedar Point, Ohio, June 22 to July 31 (Malcom E. Stickney); Harpswell 

 Laboratory, South Harpswell, Maine, June 15 to September 15, purely research. 



The Editors oe the Botanical Gazette have decided to discontinue the 

 Items of taxonomic interest, heretofore a feature of "Notes for Students." Their 

 chief purpose was to serve taxonomists in callirfg attention to new genera and to 

 new American species. There was not space enough to do this completely, and 

 anything short of completeness in such a record is unsatisfactory. Besides, this 

 useful service is now more fully rendered by the Botanisches CmtralUatt and 

 Fedde's Repertorium navarum specierum, to say nothing of the various ftirrent 

 card indexes. This does not mean that taxonomic literature will be neglected, 

 but that it will be reviewed selectively, as in the case of other literature. - 



With the present number of the Botanical Gazette, the department 

 of "NEWS" will be discontinued. Botanical news is now more promptly an- 

 nounced for American readers in Science than it can be in a monthly journal; 

 and foreign readers receive such information through journals nearer at hand.
