look on their Chamber-windows in a frofty Morn- 
ing, if they rife foon enough, and they will fee there 
fuch Embroidery made by Ice, as their own Fingers, 
were they ufed to work, and the fineft Needles, could 
not equal. 
All this, I fay, would tempt one to imagine, that 
there is fomething vegetative in what I call the Seeds 
of Froft. But that is not what I am about at prefent. 
All I contend for now is, that that which co-operates 
with the Earth’s Surface, to produce Cold, which way 
foever it produces it, is carried to and fro by the 
Air. 
Inftead of their ading like Seeds, let us fuppofe 
them to acft like inanimate Bodies : That each Particle 
ads with a determined Force ; and that, confequently, 
the more of them ad together, the greater their 
Effed. Upon this Suppofition we can eafily account 
for the different Temperament of the Air in the fame 
Seafons. For a Continuance of North-eaft Winds for 
fome Years will carry off many of thefe Seeds, or 
Grains of Cold ; and an equal Continuance of South- 
weft Winds will bring them back again; and thefe 
Periods will be longer or fhorter, according to the 
Strength or Weaknefs of the Blaft. 
And thus, at length, I have fatisfied myfelf, till I 
can find out a better Reafon, why a cold frofty 
Winter produces a dry Summer; and a mild Winter 
a wet Summer. For thefe Seeds of Cold being the 
chief Caufe of Froft, and their Strength being in Pro- 
portion to their Number, when the Winter is fevere, 
there is fo vaft a Quantity of thefe frigorific Particles 
in North- Europe, that their Strength will not foon 
be cxhaufted ; and, confequently, that the North-eaft 
Winds
