52 NOTES AND COMMENT 



Prof. W. M. Wheeler, of Harvard University; Secretary-Treasurer, 

 Dr. Forrest Shreve, of the Desert Laboratory. The first regular annual 

 meeting will be held in New York during the next Convocation week, 

 where a program will be worked out in harmony with the programs 

 of the botanists and zoologists so as to minimize serious conflict. A 

 field meeting will probably be held in Chicago in June. 



The Bulletin of the American Geographical Society has been dis- 

 continued after a career of sixty-three years, its place being taken by 

 The Geographical Review, a journal of slightly greater size but of similar 

 contents. This change is made as one that befits the widening sGope 

 of the organ of the Society and as a testimonial of the intention of the 

 Director, Dr. Isaiah Bowman, to still further improve upon the standard 

 of interest and usefulness which was maintained by the Bulletin for so 

 many years. 



Among the papers which will appear in forthcoming issues of The 

 Plant World may be mentioned: The Red Color of the Mesocarp of 

 Seeded Fruits in the Persimmon, by Francis E. Lloyd; The Weight of 

 Physical Factors in the Study of Plant Distribution, by Forrest Shreve; 

 Notes on the Ancestry of the Beech, by Edward W. Berry; A Critique 

 of the Hypothesis of the Lime-Magnesia Ratio, by Charles B. Lipman; 

 A Study of the Relation of Soil Moisture to Transpiration and Photo- 

 synthesis in the Corn Plant, by T. G. Yuncker; and The Forests of the 

 Hawaiian Islands, by Vaughan MacCaughey.
