PERSONAL AND SCIENTIFIC NEWS. 
Dr. James Croll, of the Scottish Geological Survey died on 
Dec. 15th, 1890, at the age of 69. Failing health had compelled 
him for some years to withdraw from the active pursuit of his two 
favorite sludies, philosophy his first, and geology his later love. 
Disabled for the hard physical labor of a millwright — his first oc- 
cupation — by an accident he turned his attention to science and 
became so well known that he was made Keeper of the Anderson-

was the " Philosophy of Theism," but the paper which established 
his reputation was the first of that remarkable series on "The 
Physical Cause of the Change of Climate during the Glacial 
Epoch " with which his name will alwaj's be associated. It is
