It will be seen from this that winters above the average (mild,) 

 have been followed in two instances by summers above (hot,) 

 and in three by summers below (mild) the average ; and winters 

 below the average (cold,) have been followed in two instances by 

 hot summers, and in four by mild ones, so that the popular tra- 

 dition is not at all supported by these observations. 



This is not the place to discuss the subject of climate, but many 

 of your readers will, perhaps, be interested in examining the fol- 

 lowing temperatures of a few places on the opposite shores of 

 Lake Ontario. They are taken from Dove's tables, but are un- 

 reduced for both diurnal and annual variation. 



It appears from these data (which, however, with the single 

 exception of Toronto, are very rude for such a purpose), that as 

 compared with these stations on the South side of the Lake, our 

 increased severity of winter is much more than compensated for 

 by diminished intensity in summer.

NOTICE TO MEMBERS AND SUBSCRIBERS TO THE JOURNAL. 



It having been represented to the Postmaster General by the

 to order that the Canadian Journal may be transmitted to any 

 part of Canada through the Post, at half the usual Postage.

 malities of their election cannot be complied with until the first

The Council of the Canadian Institute desirous of making

 and address of each intending contributor, together with the 

 title of the paper he proposes to read or communicate, may be 

 transmitted to the Secretary before the first clay of November
