306 DR. CHARLES CHREE: MAGNETIC DISTURBANCES AT KEVV. 



Much of the arithmetical work on which the paper is based was done by various 

 members of the staff of the Observatory Department especially Messrs. B. FRANCIS 

 and W. K. COKRIN, junior to whose care and accuracy I am much indebted. The 

 calculations were all checked by myself. The cost of tabulating the curves was partly 

 defrayed out of a grant which I received two years ago from the Government Grant 

 Committee.
