lege of the middle west. And this from a 

 president of one of the state universities: 

 I have to say in humiliation that practically 

 nothing has yet been done in this state and in our 

 institution as to tuberculosis. ... I am going to 

 take up the matter in the university next year. 

 I regard the movement as one of supreme impor- 

 tance and hope to bear my share in the beneficent 

 cause. 



What results may we expect from the 

 cooperation of all the colleges when it is 

 once secured? Each year we shall enlist 

 hundreds of thousands of the best young 

 men and women of the country. We shall 

 obtain through them the cooperation of the 

 secondary schools whose teachers they sup- 

 ply. And as our students go out into 

 every city and town and village in the land 

 to take their places as citizens of excep- 

 tional influence in their communities, we 

 shall secure the cooperation of the leaders 

 of the future. The harvest sown in the 

 college may be some years in ripening, but 

 it is no less sure. 



In summation let me say that we may 

 reasonably ask the college and university 

 to help us by giving instruction on tubercu- 

 losis in general lectures before student as- 

 semblies and in specific teaching in the 

 class rooms of the social, economic and bio- 

 logic sciences. We may ask for exemplary 

 sanitation of college buildings, for inspec- 

 tion of college herds, and for care over the 

 health of students by regulations securing 

 immunity from house infection and by the 

 early detection of incipient cases of the 

 disease. We may ask for the exertion of 

 effective influence in securing model san- 

 itary conditions in the immediate college 

 environment and for help in promoting the 

 propaganda throughout the state and na- 

 tion in every possible way.

PROPOSED PUBLICATION OF EULER'S 

 WORKS 



Strenuous efforts are now being made to 

 secure the publication of the complete works 

 of Leonhard Euler (1Y07-83), one of the most 

 prolific writers of all times on pure and ap- 

 plied mathematics. Euler lived at a time 

 when the differential and integral calculus was 

 still young, and he was most influential in 

 making this powerful instrument of thought 

 more easily available in the various fields of 

 mathematics. The enormous extent of his 

 writings has been a great obstacle in the way 

 of securing a publication of his complete 

 works and has thwarted earlier efforts along 

 this line. From a recent circular issued by 

 the Swiss Society of Natural Sciences, it ap- 

 pears that we may reasonably expect that the 

 publication of this great work will begin at 

 an early date. The following extract from 

 this circular should be of interest : 



On the initiative of the German Association of 

 Mathematicians, the International Mathematical 

 Congress, meeting at Rome in April, 1908, unani- 

 mously passed the following resolution: 



" The fourth International Congress of Mathe- 

 maticians, held in Rome, regards the publication 

 of the whole collection of Euler's works as an 

 undertaking of the greatest importance, both to 

 pure and to applied mathematics. The congress 

 gratefully welcomes the initiative taken by the 

 Swiss Society of Natural Sciences in this matter 

 and expresses the wish that the great work may 

 be carried out by that society in common with 

 the mathematicians of the other nations. The 

 congress begs the International Association of 

 Academies, and more particularly the Berlin and 

 St. Petersburg academies, of which Euler was so 

 preeminent a member, to support the enterprise 

 in question." 



Immediately on the adoption of this resolution 

 the representative of the Paris Academy, Mons. 

 G. Darboux, made known that the International 

 Association of Academies had discussed the Euler 

 question at Vienna in the preceding year, and had 

 expressed entire sympathy with the movement. 

 The correspondence which has since taken place 

 between the president of the Swiss Euler Com- 

 mittee and Mons. Darboux, as also with Herr 

 Lindemann, who had aroused interest in the 

 matter in Vienna, leads us to hope that the sup- 

 port of the Association of Academies will be
