Fabre, the incomparable naturalist, patiently waiting 

 to discover what is instinct and what is reason in insect- 

 life is, to these vintagers, an object of supreme com- 

 miseration, an imbecile in God's keeping, wherefore they 

 crossed themselves. 



Members of the University of Pisa, and other onlookers, 

 are assembled in the space at the foot of the wonderful 

 leaning tower of white marble in that city one morning 

 in the year 1591. A young professor climbs the spiral 

 staircase until he reaches the gallery surmounting the

 has spoken with no uncertain sound, and has given an 

 immediate answer to a question debated for two thousand 

 years. 



" This meddlesome man Galileo must be suppressed," 

 murmured the University fathers as they left the square. 

 " Does he think that by showing us that a heavy and

 our belief in the philosophy which teaches that a ball
