 happenings in the simplest terms, to connect par-

 formulse which sum up often repeated chains of 

 sequence how much of this there is still to do in 

 every department of inquiry. Many of the unsolved

 it will go on perhaps asymptotically. But even 

 supposing all problems of this sort were cleared up, 

 we should not have explained the world. Why 

 not ? Because the terms used are not self-explan-
