CoUe's fieneial aphorisms, from Gren. 111. 5. There 

 is little variation of heat between the tropics : it be- 

 comes greater on plains than on hills : it is never so low 

 near the sea as in inland parts: the wind has no effect on 

 it ; its maximum aad minimum are about six weeks after 

 the solstices : it varies more in suiamer than in winter : it 

 is least a little before sunrise:' its maxima in the sun 

 and shade are seldom on the same day : it decreases more 

 rapidly in the autumn than it increases in summer. A cold 

 winter docs not forebode a hot summer. 



Kirwan says, that the mean heat at the sea side is 84" — 53 

 (sine lat.) *. From this we must deduct for elevation, i" 

 for each 800 feet that wc ascend perpendicularly, wheVe the 

 declivity is about 6 feet per mile ; where 7 feet, 1" for 600 

 feet ; where 13 feet, for 500 ; where 1 5 or more, 1" for 400. 

 For the distance from the sea, we must add 1° for each 50 

 miles, between 10° and 20° latitude ; between 2.5° and 30", 

 1° for 100 miles : between 30° and 35°, we must deduct 1" 

 for 400 miles; between 35" and 70" for 150. It seldom 

 freezes in latitudes below 35°, and seldom hails beyond 60° ; 

 between these limits it generally thaws when the sun's alti- 

 tude is above 40°. The greatest cold is usually half an hour 

 before sunrise ; the greatest heat at the equator about 1 

 •'clock ; further north it is later : in latitude 50° about half 

 past 2. In latitudes above 48° July is warmer thanAugust: 

 in lower latitudes colder. At Petersburgh the greatest sum- 



mer heat is usually 79°- In every habitable climate there 

 is a heat of 60° or more, for at least 2 months. 



According to Cavallo, the greatest heat of the day in 

 July is before 3 o'clock; according to others, about half 

 way between noon and sunset.
