Therefore it is not to be wondered at that certain very 

 difficult, or perhaps impossible problems have in all ages 

 had a powerful fascination for certain minds. In that 

 curious olla podrida of fact and fiction, "The Curiosities 

 of Literature," DTsraeli gives a list of six of these prob-

 well-known follies that are omitted, while some authorities 

 would peremptorily reject Magic and Judicial Astrology as 

 being attempts at fraud rather than earnest efforts to dis- 

 cover and utilize the secrets of nature. The generally 

 accepted list is as follows : 



1. The Quadrature of the Circle or, as it is called in 



the vernacular, " Squaring the Circle."

 cury, and the Elixir of Life might perhaps be properly
