EartJiquake — A heavy earthquake shock occurred on the 

 night of 20th May at 10.15 p.m., followed by a lighter shock 

 about II. 



Aurora — There has been a marked absence of aurora for 

 many weeks, an unusual occurrence. Dr. Veeder, of Lyons, N.Y. 

 the authority on auroras, gives the monthly recurrence of the 

 aurora 26 or 27 days apart, and says when no auroras are visible 

 there is a manifest increase in thunder or other storms, as though 

 they had taken the auroras place, and disturbances of the earth 

 currents, known as magnetic storms, occur, even the solid crust 

 of the earth receiving impulses that cause tremors, and earth- 

 quakes when the conditions are favourable, because of instability 



existing therein.

July Excursion — At the last meeting of the Council it was

 •Committee expects to be in a position to make an announce- 

 ment within a few days. 



Editorial Note — In the unavoidable absence from the city of 

 Dr. Ami, the editorial work of the current issue has been as- 

 sumed by Mr. F. T. Shutt.
