IVf A new Method for compofing a natural Hijlory 
of Meteors communicated in a Letter to Dr.Jurin,

T H I S Method in general is, that in Addition to 
fuch Obfervations as fhould be made on Land, 
there might be fome Account taken of thofe alfo that 
were made at Sea j which already are by far more nu- 
merous than what were ever made afhore, or indeed 
what can be expe&ed thence for fome Ages dill to come. 
This Method occurcd to me, as I was looking over va- 
rious Journals of Voyages in my Paffage from Eng- 
land^ in which 1 was not a little furpriz’d to find tne 
following Particulars conftantly obferv’d. 
Firfi 1 There was a general Account of the Weather 
for every Day, during the Paffage of the Ship on the 
Voyage, which tho’ not quite fo exad as the Obferva- 
tions of the fame Kind that have been made on Land, 
particularly what were publifh’d by the Rev. Mr. 2Vr- 
ham , yet for all that I know, are fufficient for the De- 
fign. However, if there is any Defed in this Article, 
it is abundantly made up in another Column • which is 
a far more exaft Regifler of ih z'Dire Elion of the Winds 
than was ever kept afhore , being an Account thereof to 
every two Hours in the Day, This Article may per*
