 Czechoslovakia, and should be in his hands by 

 the end of May, 1922. Money contributions 

 should te made payable to the Mendelfeier-

COLLOID CHEMISTRY AT THE UNIVERSITY 

 OF WISCONSIN 



The chemistry department of the University 

 of Wisconsin announces that Professor The. 

 Svedberg, of the Universitj- of Uppsala, will be 

 in residence during the second semester of the 

 scholastic year of 1922-23 and the summer 

 session of 1923. 



While at Wisconsin, Professor Svedberg will 

 organize and direct the research work in colloid 

 chemistry, and will also give two lectures each 

 week on the subject and conduct two weekly 

 seminaries. One seminary will be devoted to 

 the broader aspects of colloid chemistry and 

 the other to its biological applications. 



Professor Svedberg is recognized as one of 

 the international authorities on the subject of 

 colloid chemistry. He is the author of many 

 papers dealing with the fundamental princi- 

 ples of colloid chemistry and has written thu 

 best known treatises on the preparation of col- 

 loids. His work has been recognized by the 

 award of numerous prizes and special research 

 funds and he lias been honored by numerous 

 foreign societies. 



During the summer session of 1923, lasting 

 for a i^eriod of six weeks, the lectures given 

 during the second semester will be repeated for 

 the benefit of educators and research woi'kers 

 who find it impossible to attend the university 

 diu'ing the regular session. A seminary will 

 also be conducted throughout the summer ses- 

 sion. 



Advanced woikers who desire to do work 

 under the direction of Professor Svedberg 

 should communicate with Professor J. H. 

 Mathews, director of the course in chemistry, 

 since only a limited number of research workers 

 can be accommodated. 



YALE UNIVERSITY AND DR. CHITTENDEN 



At the regular monthly meeting of the Yale 

 Corporation, held on March 11, the following 

 I'esolution was adopted in connection with the 

 resignation of Dr. Chittenden as director of 

 the Shelfield Scientific School, which takes 

 effect at the close of the present university 

 year : 



Even ill his undergraduate clays in tlie Sheffield 

 Scientific School Director Odttenden had begun 

 to pave the way to a distinguished career as a 

 teacher and investigator in physiological chemis- 

 try, for the development of which as an inde- 

 pendent branch of study he lias been responsible 

 not only at Yale but in large measure in the 

 United States. His was in many respects the 

 path of a pioneer in a borderline science which 

 inevitably led both at home and abroad to recog- 

 nition and honors in which the institution that 

 Director Chittenden served has shared abundantly. 



Not less successful has been Dr. Chittenden's 

 leadership as director of the Sheffield Seieutific 

 Scliool for nearly a quarter of a century. His 

 unflagging energy and broad vision have con- 

 tributed largely to increase the material resources 

 of the school, to enlarge the scope of its useful- 

 ness as an institution for professional training in 

 science, and to stimulate and encourage investi- 

 gation. Tlie recognition at Y'ale of the important 

 part which the study of science should play in 

 modern education is due in no small degree to 

 Dr. Chittenden's influence. Kesearch at Y'ale has 

 ahvays found a staunch supporter and advocate 

 in him. 



To a man of Dr. CJiittenden's training and 

 ideals even the partial abandonment of the pur- 

 suit of science necessitated by the call to an 

 executive post must have meant a personal sacri- 

 fice. He has accepted this, as he has undertaken 

 many other public tasks, in a spirit of service 

 which deserves grateful recognition on the part of 

 Yale Universiy. 



The Yale Alumni Weehlij says in an edi- 

 torial article : 



The resolutions adopted on the resignation of 

 Director Chittenden by the Y'ale Corporation 

 place a richly merited emphasis on the character
