SCIENCE.

of the hydration of salts in aqueous solutions. 

 This subject, which constitutes one of the 

 most important as well as one of the most 

 difficult of the unsolved problems relating to 

 solutions, is being attacked by two independ- 

 ent methods by Mr. Edward W. Washburn 

 and Mr. Kichard C. Tolman. A series of 

 eight articles describing the researches made 

 in the laboratory during the last two years is 

 about to be submitted to the Carnegie Insti- 

 tution for publication. The research labora- 

 tory has been assisted on the financial side by 

 a further grant of five hundred dollars from 

 the trustees of the William E. Hale research 

 fund, by a gift of two hundred dollars from 

 Mr. Samuel Cabot and by one of three thou- 

 sand dollars from one of the professors of the 

 institute. 



THE AMERICAN SOCIETY OF NATURALISTS 

 AND AFFILIATED SOCIETIES. 



The American Society of Naturalists and 

 affiliated societies will meet at the University 

 of Michigan, Ann Arbor, in Convocation 

 week. The Central Branch of the society will 

 meet, but we understand that the Eastern 

 Branch will hold no meeting this year. There 

 will meet in conjunction with the American 

 Society of Naturalists the American Zoolog- 

 ical Society, the American Physiological So- 

 ciety, the American Association of Anatomists, 

 the Society for Plant Morphology and Physi- 

 ology and the American Society of Bacteriolo- 

 gists, the latter society having suspended its 

 rules of meeting only in the eastern states. 



The American Psychological Association 

 and the American Philosophical Association, 

 which have in recent years met with the 

 Naturalists, will meet this year at Harvard 

 University. On this occasion Emerson Hall, 

 the new building for philosophy and psychol- 

 ogy, will be formally opened. 



THE NEW ORLEANS MEETINC OF THE 



AMERICAN ASSOCIATION FOR THE 



ADVANCEMENT OF SCIENCE. 



The people of New Orleans have organized 

 local committees to take charge of the arrange- 

 ments for the meeting of the association, which 



will be held from December 29 to January 4. 

 The permanent secretary writes from New 

 Orleans that the local committees are en- 

 thusiastic and will work hard for the success 

 of the meeting. That it will be an important 

 and siiccessful meeting is assured, provided 

 the attendance is satisfactory. 



The question of railroad rates has not as 

 yet been thoroughly settled, but it seems likely 

 that a one-fare rate will be secured from most 

 of the railroad associations. The opportunity, 

 therefore, to members of the association (es- 

 pecially from the northeast) to visit New 

 Orleans, will be an exceptional one. New 

 Orleans is a most interesting city on account 

 of its historical associations, its cosmopolitan 

 population, its extraordinary natural advan- 

 tages, the wonderful flora of its parks and sur- 

 roundings and the many important industries 

 which center at the mouth of the great water- 

 way of the United States. 



Members who have not visited New Orleans 

 should take advantage of this chance and mem- 

 bers who are familiar with the city will gladly 

 greet the opportunity to revisit it. Nearly 

 all of the sections and affiliated societies will 

 be accommodated in the lecture halls of the 

 Tulane University (which is the state uni- 

 versity of Louisiana) with new and well- 

 equipped buildings. It is likely that the meet- 

 ing of the Social and Economic Section will be 

 held in the board of trade rooms in the central 

 part of the city. The university itself is 

 within easy access of the large hotels by 

 trolley, the time occupied in the journey being 

 about twenty-five minutes. The St. Charles 

 Hotel has been chosen as hotel headquarters 

 and promises of low rates to members are 

 also made by the Grunewald, Cosmopolitan and 

 other hotels. It will be well for members to 

 write well in advance and engage rooms. 



The honorary president of the local com- 

 mittee will be President E. B. Craighead, of 

 the Tulane University. The executive presi- 

 dent will be Professor George E. Beyer, of 

 Tulane University; secretary, Henry M. Mayo, 

 of the New Orleans Progressive League, and 

 treasurer, Mr. Clarence F. Low, of the Liver- 

 pool, London and Globe Insurance Company. 



The subcommittees are formed as follows :
