Tbus the cities of the Upper Lakes (excepting Duluth) do not 

 differ greatly from those of the Lower Lakes in annual tempera- 

 ture, ibut the annual range of the former is somewhat larger, 

 owing in part to their greater distance from the ocean. 



The only ohservations upon the temperature of the Lower 

 Lakes, off shore, which the writer has met with, are those made 

 toy Professor Dewey in 1838 and quoted in the report of Professor 

 Coffin. " The temperatures are the averages of ohiservations 

 made at interTals of six or eight miles acrosis Lake Ontario, 

 from the Genesee River to Coburgh, Canada (not including those 

 made near the shore), about a foot below the surface." For com- 

 parison, the mean temperature at Albany for the several half 

 months during which the oibservations were made is also given 

 here.
