perpendicular to the direction of its motion which are cut by the

magnet.

OBITUARY. 
Rev. W. B. Crarke, a geologist of eminence in Australia, as 
well as a clergyman of the Church of England, died on the 16th 
of June last at St. Leonards (near Sydney), New South Wales, 
* the age of eighty-five. Mr. Clarke was an enthusiastic worker 
geology. His labors in Australia were continued for more 
tikes forty years, and resulted in many important discoveries and 
great ee gress to Australian geology. The first announcement

discoveries in Australia and Australasia, with one on the Causes

e was a man of great excellence and of earnestness in his parish 
work as well as in his field explorations.
