 deposits of coal, salt, and mineral oil. so that all the minerals and rocks which are mined 

 will be considered.

Athenrcum. — " Mr. WriKht not only appeals to the specialist, but also gives the general reader a clear 

 insight into the subject : he describes glaciers, and discusses the physics of ice ; he explains the different kinds

 subjects throughout are treated in lucid language, and illustrated by excellent plates."
