is by far the largest of those treated in this 

 part, having 255 species. In this family the 

 largest genera are Lithophragma with 20 spe- 

 cies; Heuchera, 72; Therefon, 10; Saxifraga, 

 7; Muscaria, 7; Micranthes, 56; Spatularia, 

 7, and Leptasea, 15. The next family in 

 number of species is Hydrangeaceae with 52, 

 and here the genus Philadelphus is the domi- 

 nant one, with 36 species. Of the remaining 

 families only Cunoniaceae and Hamamelida- 

 ceae have more than one species, the former 

 having two and the latter four. The total 

 number of species described in this part is 

 317, among which one finds a considerable 

 number of new species.

WORE AT THE LAKE LABORATORY FOR 

 THE SEASON OF 1905. 



The work in the past summer at the Lake 

 Laboratory was, perhaps, the most successful 

 of any session that has been spent there and 

 distinctly encouraging for successful sessions 

 in the future. Of the twenty-six students 

 enrolled, eleven were college or university 

 graduates; two having the title of Ph.D. and 

 five that of master. Fifteen of the number 

 were engaged in advanced or research work 

 of university or graduate grade and in most 

 cases for university credit; four were engaged 

 in advanced work under the direction of the 

 instructors, while six were doing independent 

 research work for part or all of the time. 

 Seven of the number are teachers in a uni- 

 versity or college and two teachers in high 

 schools, eleven being now or recently engaged 

 in teaching in some capacity. 



The following institutions were represented 

 there this season: Cincinnati University, Co- 

 lumbia University, Denison University, De 

 Pauw University, German Wallace College, 

 Johns Hopkins University, Kenyon College, 

 Ohio University, Ohio Northern University, 

 Ohio State University, Ohio Wesleyan Uni- 

 versity and Miami University. If we include 

 institutions which have been represented with- 

 in the last few years we should add to these, 

 Chicago, Michigan, Nebraska, Stanford, Am- 

 herst, Cornell, Antioch and Fargo, which have 



been represented either by investigators or by 

 students. 



A very enjoyable and profitable feature of 

 this season's session was the meeting of the 

 American Microscopical Society which brought 

 a number of prominent scientific workers from 

 various parts of the country and especially 

 from Ohio, the Ohio Academy of Science hold- 

 ing a field meeting at the same time. This 

 meeting consisted of the presentation of a 

 number of scientific papers which were read 

 at the laboratory and to which all the stu- 

 dents were invited; an evening lecture by the 

 president and social meetings, the most prom- 

 inent of which was the luncheon which the 

 university gave to the visiting members. 



As heretofore, much attention has been 

 given to original investigation and some of 

 the more important topics studied this year 

 are : ' The Brain of Amia,' by Professor 

 Charles Brookover, Buchtel College; 'The 

 Naididse of Cedar Point,' by Professor L. B. 

 Walton ; ' Studies on the Life History of the 

 Catfish and Investigations of Protozoa,' by 

 Professor F. L. Landacre ; ' Studies of the 

 Insects which act as Scavengers of the Beacli 

 Debris,' by W. B. Herms; ' Correlation Studies 

 of Toads,' by Professor W. E. Kellicott; 'On 

 the Flora of Cedar Point,' by Otto E. Jen- 

 nings, and on the ' Protozoa of Sandusky Bay,' 

 by Miss L. C. Riddle. The results of some of 

 these studies will appear in published papers 

 in the near future; others will doubtless be 

 continued for more complete results.

THE BRITISH ASSOCIATION} 

 The list of officers for the seventy-sixth 

 meeting of the British Association, which will 

 open at York on August 1, next, is now prac- 

 tically completed. The meeting promises to 

 be one of great interest. It was at York that 

 the association came into being in 1831, when 

 Lord Milton (afterward Lord Fitzwilliam) 

 was president, and the attendance numbered 

 only 353 persons. Thirteen years later the 

 association again met in York, with the Eev. 

 G. Peacock as president, and yet a third time 



' The London Times.
