The Darwin Commemoration — Thougiits — Species. 



The present week (June 22nd-26th) brings us face to face with the 

 " Darwin Commemoration at Cambridge," and one of our two famous 

 Universities is celebrating the " Centenary " of Darwin's birth and 

 the "Jubilee" of the publication of his epoch-making work, Tiie 

 Oriijin of Species hij means of Natural Selection, or the Preservation of 

 favoured Races in the Struf/gle for Life, a work that has largely changed 

 the whole trend of human thought during the last half century. 

 Cambridge University is, during the present week, entertaining- 

 scientific men from all parts of the world, in honour of the memory 

 and work of this, one of her greatest sons — greatest one would have said, 

 were it not that Newton also acknowledged Cambridge as his University. 

 What Newton did to bring the laws governing matter within the 

 understanding of the human intellect, Darwin did with the laws 

 governing life. The order of Commemoration is officially announced 

 as follows : — •
