 Mi)iintains you may hear an liulian explain llic raiiihow with all 

 ils beautiful colors as the serpent that ahrade-s the tirnianu'nt of ice 

 to give us snow in Winter and rain in Sununer. He sees itd coil, 

 he sees its stripes, he sees it against the sky of ice, arttl he sees it as- 

 sociated with rain which falls from above, and so he calls it the Great 

 .Serpent of the .Storm. The metiiod of thought by which he arrives 

 at this <-onclusiou is subjective ami superficial analogies arejjsed as 

 the basis of conclusions. The man of science .sees in the rainbow 

 the analysis of white light into it^ constituent colors. 



The method of thought is objective, and essential iiomologies are 

 used as the basis of his explanation. But these two methods of 

 thought appear in all stages of civilization and among all peoples. 

 Subjective thought aud anal.>gic reasoning appear on the oue hand, 

 objective thought and homologic reasoning ou the other ; aud it thus 

 happens that in all the domain of Nature there is a vast body of 

 phenomena that receives two explauation.s — a popular aud a scien- 

 tific. But,gra<lually, the scientific method is becoming the popular 

 method, and scientific methods are being accepted and understood 

 more aud more, as the years pass, by the intelligent people of civil- 

 ization ; and it is the purpo.se of the lectures inaugurated this day 

 to bring popular and scientific thought into harmony. Such is the 

 tjisk Professor Gill proposes for himself. May lie abundantly suc- 

 ceed.
