Charles Robert Darwin. 



77 



twenty years of study and investigation. It is a book to be read and 

 re-read, and in which something new will be found at each perusal. 

 His " Descent of Man," taken in connection with his " Expression of the 

 Emotions," proves beyond a doubt, that between the bodily features 

 and mental powers of animals and man, there exists only a difference 

 of degree. 



Mr. Darwin never was a man of robust health, and many of his re- 

 corded observations ware made while confined to the house. Fortu- 

 nately he leaves behind him sons, who have already done much toward 

 the increase of human knowledge, and upon whom it is hoped, but can 

 hardly be expected, the mantle of the father has fallen. Taking Mr. 

 Darwin's work as a whole, it constitutes a contribution to science, and 

 a monument to himself, which will be a lasting one. And even if the 

 Darwinian theories of natural selection, and the struggle for existence 

 should fall to the ground, his work will be remembered. It will make 

 him live in the memory of mankind as long as science holds a place 

 upon earth. Charles Robert Darwin is dead, but his spirit, and the life 

 which he has infused in the whole scientific and material world survives 

 him, and will continue to animate students for all time to come. 



NOTICE OF THE WORK OF PROF. J. D. WHITNEY 

 ON "THE CLIMATIC CHANGES OF LATER 

 GEOLOGICAL TIME ST 



By S. A. Miller. 



The second part of the very excellent work by Prof. J. D. Whitney 

 on climatic changes, has appeared in the memoirs of the museum of 

 comparative zoology, at Harvard College. It is no doubt the best con- 

 sidered work that has been published in America upon this subject, 

 and withal is very readable. In view of the statements so repeatedly 

 made at the late Forestry Convention held in our city, that the 

 destruction of forests produces important changes in the climate, a 

 dessication of the earth, and the ruin of the people, it will not be un- 

 interesting to some of our readers to know that this whole subject has 

 been treated by an eminent scientist, who has shown that the cutting 

 away of the forests has no such effect, that man has not been able to 

 effect a noticeable change in the climate of any region, and that the
