Some Climatic Conditions of Ohio.

bula. The average for Milligan just given I think is probably 
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 Perry 
County 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 minimum 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 County, not more than fifty miles from the Ohio 
River, where the range is as small as anywhere in the state, — 
(Milligan 115° range and Marietta ioo°). 
The greatest ranges among the fifteen stations for any individ- 
ual year were, as far as the records showed, at Milligan in 1899, 
140 0 F. (39 0 to ioi°) and at Findlay the same winter, 12 1° F. 
(22 0 to 99 0 ).
