ject to the cooperation of American mathe- 

 maticians. 



On the occasion of the sixtieth birthday of 

 Professor David Hilbert, of the University of 

 Goettingen, his friends, colleagues, and former 

 students presented to him an address, an album 

 of photographs, and a memorial volume of 

 mathematical papers. Among those who joined 

 in these remembrances were over sixty-five 

 American friends and former students. The 

 celebration was directed by a committee con- 

 sisting of Professors 0. Blumenthal (chair- 

 man), R. Courant, G. Hamel, E. Hecke, A. 

 Sehonfiies, and (for America) E. R. Hedriek. 

 The mathematical papers of. the memorial vol- 

 ume will appear separately either in the Matli- 

 ematische Annalen or in the Mathematische 

 Zeitschrift. 



The preparation of the complete edition of 

 the works of Sophus Lie, undertaken in 1912 

 by Teubner, but suspended because of the 

 greatly increased cost of printing, will be re- 

 sumed with the financial support of the Nor- 

 wegian Mathematical Society. The title of the 

 edition will read: Sophus Lie, Gesammelte 

 Abhandlungen, im Auftrage des Norwegischen 

 Mathematischen Vereins und mit Unterstiitzung 

 der Akademien zu Kristiania und Leipzig, 

 herausgegeben von Friedrich Engel und Paul 

 Heegaard. It is planned to publish seven vol- 

 umes, of which volume three, the first to ap- 

 pear, is HOW in press.
