edges of the car window, the lengths, which determined the angle

Dr. Engelmannn, President, in the chair. Twelve members 

 present. 



Mr. C. Crosswell read a paper on " Symbolism," followed by 

 another on " The Sun-god of the Mound-builders." Mr. Cross- 

 well pointed out similarities between the decorative forms on 

 mound relics and those of ancient races of the old world, and 

 argued a unity of origin. 



Judge Holmes urged that the same decoration might originate 

 independently in different nations, just as arrow-heads of stone 

 are produced all over the world at certain stages of development, 

 and that, in accounting for the presence of man on this continent, 

 we must go back in geological time to a period when the configu- 

 ration of the continent was quite different from what it is now.
