 H. A. Koch, of Columbia, Mo., Walter Bernays, City 

 Chemist. 



Prof. F. E. Nipher gave a Popular Discussion of some 

 present ** Problems in Physics." 



He dwelt principally on the present conception of the 

 nebular hypothesis and its bearing on the evolution of the 

 universe, in connection with the influence upon and of elec- 

 tricity. He presented some interesting photographic nega- 

 tives, gathered during his scientific researches. 



He also entered into an explanation and comparison of 

 galvanic, static, and mechanical electricity. His deductions 

 from a careful study of the phenomena and conclusions based 

 thereon, led to the assumption that the sun is the basis of all

 from that center at various epochs. 



And he expressed the opinion, that when the art of over- 

 coming inertia is once understood, all mechanical problems 

 will have been near solution.
