Some Clbnafic Conditions of Ohio.

bula. The average for Milligan just given I think is probaljl\- 

 too low. The records have been kept for only eight years and 

 during this time has occurred the exceptionally low temperature 

 of 1899 which must necessarily have unduly influenced the aver- 

 age. Yet it must be acknowledged that the region about Perr}- 

 Count>- and northwestward shows very low maxima; throwing out 

 altogether its two lowest records, Milligan would still hold the 

 lowest minima among the fifteen stations, — or, even leaving 

 Milligan out altogether, the map will still remain practically 

 unchanged. 



Average Extreme Range of Tempeature. 

 (Plate IV Map VIII. ) 



By average extreme range of temperature is here meant the 

 difference between the average of extreme mininuun temperatures 

 and the average of extreme maximum temperatures. 



Considered thus the .smallest range (The most equable temper- 

 ature) is to be found along the shore of Lake Erie and in the 

 immediate vicinity of the Ohio River, while the region of greatest 

 extremes occurs in a strip commencing at the northwest corner of 

 the state and continuing southeastward reaching its culminating 

 point in Perry Count>', not more than fifty miles from the Ohio 

 River, where the range is as small as an} where in the state, — 

 (Milligan 115° range and Marietta roo°j. 



The greatest ranges among the fifteen stations for an\' individ- 

 ual year were, as far as the records showed, at Milligan in 1899, 

 140° F. (39° to 101°) and at Findla}- the same winter, 121° F. 

 (22° to 99°).
