Unselfish Science. — One of the happiest 

 features of the opening session of the Ameri- 

 can Association at Detroit was the welcom- 

 ing address of ex- Senator Thomas W. Palm- 

 er. Amid the general scramble for money 

 power which characterizes the present age, 

 he said, " it is gratifying to know that there 

 is an increasing number of men and women 

 who, ignoring the common objects of ambi- 

 tion, have devoted themselves to and are 

 diligent in the unselfish pursuit of truth." 

 These men and women find in the phenome- 

 na of Nature history related with accuracy 

 and predictions certain to be verified. " For- 

 merly it was considered that there was a con- 

 flict between science and religion. Let us 

 hope that that day has long been passed, and 

 that the more enlightened public recognizes 

 that religion has to do with the spiritual 

 nature of man and science with physical 

 phenomena." The speaker had been seek- 

 ing a definition of science, and conceived as 

 the most satisfactory one to his mind " the 

 classification of phenomena to the end that 

 principles may be established and declared 

 from which may be deduced rules of action 

 that shall be applicable to particular cases. 



When did science first originate ? Back of 

 the dawn of history, when primeval man, 

 emerging from the shelter of the cave be- 

 fore he had even built him a hut, com- 

 menced to apply the force of Nature to his 

 use. . . . How did science originate ? By 

 extended observations, experience, and com- 

 parison. The first savage who played in the 

 water with his reed as a baby does with a 

 straw, blowing and sucking it, gave the first 

 illustration of hydraulics. The little savage 

 playing in the woods at the ancient game 

 of seesaw would find that the heaviest boy 

 would have to sit nearest the center, and 

 this would give the first suggestion of the 

 lever.'' 



The Beginning of Photography. — A 



bust of Daguerre, the inventor of the pio- 

 neer of all photographic processes, was dedi- 

 cated at Bry-sur-Marne, where he died, June 

 27th, in the presence of representatives of 

 the French Government. The idea of fixing 

 by some chemical process the pictures which 

 were formed on the screen of the camera 

 obscura had been entertained, and many per- 

 sans had tried to discover the art before
