are as the Sines of the Latitude, and generally 

 they are as the Sines of the Latitude into the Sines 

 of Declination. IV. That the Equinoctial Days 

 Heat is every where as the Co-fine of the Lati- 

 tude. V. In all places where the Sun fets, the 

 difference between the Summer and Winter Heats, 

 when the Declinations are contrary, is equal to 

 a Circle into the Sine of the Altitude at fix in 

 the Summer Parallel, and confequently thofe dif- 

 ferences are as the Sines of Latitude into, or 

 multiplied by the Sines of Declination. VI. From 

 the Table I have added, it appears, that the 

 Tropical Sun under the Equinoctial, has, of all 

 others, the leaft Force. Under the Pole it is 

 greater than any other Days Heat whatfoever, 

 being to that of the .Equinoctial as £ to 4. 



From the Table and thefe Corollaries may 2 

 general Idea be conceived of the Sum of ali the 

 Actions of the Sun in the whole Year, and that 

 part>of the Heat that arifes fimply from the Pre- 

 ience of the Sun be brought to a Geometrical 

 Certainty : And if the like could be performed 

 for Cold , which is lomething elfe than the bare 

 Abfence of the Sun, as appears by many In fian- 

 ces, we might hope to bring what relates to this 

 part of Meteorology to a perfect Theory,
