CONGRESS OF ARTS AND SCIENCE. 29 



would agree with Titchener as to introspection, but in his address 

 minimized the importance of sensations, and of just those simple, ' pre- 

 sented ' aspects of experience which Titchener had emphasized as the 

 most promising for study. Hall warned the psychologist against mathe- 

 matics, while Cattell correlated psychology with the physical sciences 

 and emphasized the need of exact methods, and Titchener found a 

 large place for quantitative work. The psychology of Ward and 

 Hoeffding seemed tenuous by contrast with that of all these others, 

 while that of Janet and Prince occupied a place apart. Yet all were 

 able discussions of psychology of some sort, and beneath the troubled 

 surface was a common interest in ' minds,' many fathoms deep. 



In the section for social structure there were three speakers, the 

 noted Austrian field marshal, Gustav Eatzenhofer, of Vienna, the 

 eminent social philosopher, Professor Toennies, of Kiel, and our own 

 distinguished sociologist and paleobotanist, Lester F. Ward, of the U. 

 S. National Museum. 



One would despair of doing justice to the eminent representatives 

 of the great and beneficent science of modern medicine, even if there 

 were space for the attempt. Happily here, as perhaps generally in 

 the case of the so-called utilitarian and other applied sciences, it will 

 only be necessary to mention the names of a few of the leaders that 

 addressed the congress to awaken appropriate associations in the 

 reader's mind. For, most of the distinguished visitors who shared 

 in the work of these sections enjoy, in addition to scientific eminence, 

 a merited popular fame. Professor Eonald Boss, of the School of 

 Tropical Medicine at Liverpool, whose name is a household word 

 through his work on the role of the mosquito in the etiology of malarial 

 fever, came for preventive medicine; Sir Lauder Brunton, of London, 

 and Oscar Liebreich. of Berlin, for therapeutics and pharmacology; 

 T. Clifford Allbutt, of Cambridge, for internal medicine; Sir Felix 

 Semon, of London, for otology and laryngology; Theodor Escherich, 

 of Vienna, for pediatrics; Shibasaburo Kitasato, of Tokio, bacteriolo- 

 gist and possibly Japan's most eminent man of science, for neurology. 

 Many of our ablest American physicians and surgeons addressed the 

 medical sections. In the only section which the writer was able to 

 attend, that of psychiatry, after the excellent papers by Dr. Charles 

 L. Dana, of Xew r York, and Dr. Edward Cowles, of Boston, interesting 

 remarks were made by several workers in neurology, psychiatry, and 

 outlying fields, including such men as Janet, Hall, Ladd, Marshall, 

 Prince, Meyer and Putnam. 



The sections in technology, including the various branches of engi- 

 neering, technical chemistry and agriculture, were conducted by prom- 

 inent Americans, although the interest in this part of the program 

 was scarcely commensurate with its importance. President Hum- 

 phreys, of Stevens Institute, Professor Kennelly, of Harvard, Mr. 

 John Hays Hammond, of New York, Professor Liberty H. Bailey, of
