of making fuch Obfervations, in order to condud a Ship 
fafely thro* the Ocean, whether the philofophical Part 
of Mankind (hall think fit to improve them in their In- 
tereff, or no : However, I would not be underflood, by 
any Thing that has been faid upon this Head, to dero- 
gate from the Defign of obferving on Land , for that 
likewife has many Advantages, that we can by no 
Means pretend to in the New Method. 
I fhould protract my Letter to anunreafonable Length* 
did I enter profeffedly upon the particular Advantages 
and Benefits, that may accrue from fuch a Tabular Re- 
gift er of Marine Obfervations , as I have propofed. I 
lhall mention therefore only two Things. 
Firfty We may be able from this Method to define 
with a great deal of Exadnefs, the Bounds and Limits 
of all confiderable Winds j for as there are at all Times 
in the Year fome Hundreds of VefTels at Sea, it is of 
the fame Importance in our Cafe, as tho’ there were fo 
many diflant Cbfervatories there j and that the Know- 
ledge of thefe more extenftvem& general IVinds would 
be of confiderable Ufe, none will deny, that fhall at- 
tentively confider it ; for hereby we may be able to 
judge, in what Place fuch a Wind has its Origin, how 
long a Time it continues, with what Velocity it moves, 
where its greatefl Strength is, and how great a Part of 
the Earth it paffes over. Perhaps alfo, in Procefs of 
Time, by this Means, we may arrive to fo much Skill, 
as to judge with fome confiderable Certainty, from the 
Rife or Beginning of a Wind, what its Effed and blue 
lhall be \ which will be of as great Importance in Navi- 
gation, , as any Thing flill wanting. Again, from fuch 
Marine Obfervations of the more extenfive and lading 
Winds, it is not impoflible, that we fhould be able to.
