TO THE 
RIGHT HONOURABLE 
ARTHUR 
EARL of AN6LESET 
One of the LORDS of His Majeftks moft Honourable 
Privy Counfel, &c. 
My Lord, 
OVR Lordfhips many favours towards me ^ and mine 
own engagements to record the modern Refufiitations 
and Advancements of the Fhilofophical Sciences , for 
which you have alwaies Jhewd a more than Ordinary 
propenfion » do^ in all reJpeSs^ both oblige and encourage 
me to dedicate this Volume of Philo(bphical Tranfa^tioos to jour 
Lordjbip. 
My Lord^ it hath been reported , that fhilofophy and all kinds of 
polite Literature have commonly retired to the objcureji receffis , for 
Jbelter from the noife of War ^and have expired or been almoft extin* 
guijht by public^ Calamities. But thefe our Generous Philofophers^ 
whom I have devoted my fervices to^ held out in all the Combuftions 
of our former Wars i when our potent Neighbors ajptulted us on all 
fdes^iandwhen the Pejiilence and Fire had wafted our Mother City. 
And they brought in not a few additions of Materials and Aids^ to 
all that had been ejfay din former Agesy or had been invented or pro* 
ficutedbythe modern enterprizes of thofe admirable Men^ ourGW^ 
bert, Galiteus, <?«r X^^r^BaconjPeyrcfkejTorriceHius^Gaflendu^, 
Dcs-CarteSjHarvcy, and many others worthy of everlafting monu^ 
ments. Theje were bright Stars of the fir jl magnitude^yet their greats- 
eft Defigns were lately iUuft rated, enlarged, methodized^ and^fome 
way or other y improvedto more maturity and perfeSion'^ as may be 
feen in the Hiftory of the R.Socicty, and fometimes more particu^ 
larlf in the rude Mifccllanies of theft TranfaSions, 
So much have the nohleftArts flourifit amongfl mever ftnceHis 
Mdjeiiies moft anf^iciosss Reftauration (partly by the recovery of An* 
tiquities ^partly by recent aides ^ and fucceftful Inventions^) even in 
thefe roHgheft times of publick^confliSs, that it may remain for afuffi-
