SCIENCE.

be more of them. Above all, then, let us 

 seek to keep company with America in the 

 nurture of science. Let us unhesitatingly 

 allow to the Americans what they have 

 which is as good or better than ours; let 

 us receive it from them gladly. And if 

 we, through unceasing vigorous perform- 

 ance, can preserve for ourselves their re- 

 spect and their attention, we shall, in the 

 field of the sciences, help to knit closer the 

 natural bond which exists between Ger- 

 many and America." 



Young Americans have, up to now, gone 

 to Germany to learn from her teachers, but 

 the time has arrived, Waldeyer continues, 

 when German and European students 

 should also go to America to widen their 

 culture. This scientific intercourse be- 

 tween person and person, university and 

 university, academy and academy should 

 be favored in every way possible. "Let 

 us be as liberal to them as they are toward 

 us in the reception of those who seek knowl- 

 edge, in offering to them all that they need. 

 Let their published researches be found in 

 our libraries also, at least in the great 

 Eoyal Library of the capital of the empire. 

 Let us show them in all things that on 

 coming to Germany they come to a people 

 of intellectual affinity, under whose polit- 

 ical and social institutions even they, with 

 their free views, may have a feeling of 

 well-being. That they do the same for us 

 can be said, to their praise, by all who have 

 been their guests. ' ' 



Germans should act toward America, he 

 believes, as Americans do toward Germany ; 

 they should try to form a correct judgment 

 of the scientific work of Americans by 

 personal knowledge; more than hitherto, 

 Germans must instruct themselves by visit- 

 ing the country itself. It would do no 

 harm if every year a number of German 

 students went to America to widen their 

 horizon. The plan of exchanging univer- 



sity professors, already introduced, is 

 highly commendable and should be further 

 realized. While he does not feel called 

 upon to give advice to Americans as to 

 their future relations to Germany, Wal- 

 deyer says thai he knows that, if Germans 

 can remain at the high scientific level they 

 have hitherto occupied, Americans will 

 need no advice ; they will gladly maintain 

 their old relations as regards science, and 

 will extend them. ''And thus, aside from 

 all else, looking purely at science and its 

 service, will not, in such intercourse, the 

 noblest and highest mission be fulfilled: 

 the advancement and elevation of culture 

 from people to people?" 



It is difficult in an abstract to do any- 

 thing like justice to such an address. All 

 who are familiar with the beauty of Wal- 

 deyer 's literary expression will desire to 

 read the report in the original.

SCIENTIFIC BOOKS. 

 A Select BihliograpJvy of Chemistry IJ^.92- 



1902. By Henry Cx\rrington Bolton. 



Second Supplement. City of Washington, 



published by the Smithsonian Institution. 



(Smithsonian ' Miscellaneous Collections, 



Part of Vol. XLIV.) 462 pp. 



The first volume of Dr. Bolton's ' Select 

 Bibliography of Chemistry' brought the lit- 

 erature down to 1892. The first supplement 

 continued the work down to the close of 1897. 

 In 1901, Section VIII., ' Academic Disserta- 

 tions,' was published separately. The present 

 work continues the whole work down to the 

 close of 1902, and adds many titles, especially 

 of academic dissertations, which had been 

 overlooked in the earlier volumes. The fol- 

 lowing table will give an idea of the space 

 occupied by the different portions of the book : 

 Section I., ' Bibliography,' 5 pages ; Section 

 II., 'Dictionaries and Tables,' 6 pages; Sec- 

 tion III., 'History of Chemistry,' 11 pages; 

 Section IV., 'Biography,' 15 pages; Section 

 v., ' Chemistry, Pure and Applied,' 162 pages ; 

 Section VI., ' Alchemical Literature of the
