make a probable Judgment of the Effed and Influence 
of the Wind upon the Weather ; which, for what Caufe 
I know not, I have frequently obferved at Sea, to change 
and alter, according as that doth. 
Secondly , From collecting all fuch Meteorological 
Obfervations as are made at Sea, we may reafonably 
expect to come to the Knowledge of fuch Winds, as pre- 
vail moft in particular Latitudes. Tho’ the Wind is a 
very uncertain Meteor, there is no Doubt, but rhat in 
fome Places, it has a very different Courfe from what it 
has in others. If I miftake not alfo, it has been fre- 
quently obferved, in fome particular Places, that the 
Courfe of the Wind in one Year has been much the 
fame as in others and tho’ there has been no particu- 
lar Order or Exadnefs yet difcover’d, yet the prevalent 
Winds, ox the greater Number of Winds have been, in 
both Cafes, according to the fame Diredion : In thefe 
Parts of the World it is remarkably fo. We can’t, in- 
deed, exped to difcover the Reigning or Prevalent 
Winds of fuch Latitudes , as are very diffant from the 
Tropic ks, by as eafy an Obfervation, as the Trade- Winds 
and Mon/dons , which are in the Torrid Zone , were 
firft found out. However as it has been after many 
Obfervations, that the Courfe of tho Fix'd Winds 
was determin’d, we may alfo hope, that Time and In- 
duftry may bring us to a much better Knowledge than 
what we have at prefent, of thefe which are more Va- 
riable. I need not fay of how much Importance it 
would be to the Trading Part of the World, were we 
able to define the more frequent and reigning Winds of 
every Climate ; for as -the Probability of Voyages 
might then be calculated in the fame Manner as 
that of other Chances, the Sailor might then better 
know
