 A characteristic feature of mathematics in 

 the last half century is the increasing atten- 

 tion paid to the foundations and rigorous de- 

 velopment of this science. In analysis this 

 movement began with Gauss, Cauchy and 

 Abel in the early years of the nineteenth cen- 

 tury and found its greatest exponent in Weier- 

 strass. The movement thus begun has been 

 continued by such men as Riemann, Dede-
