fat* improv’d snd advanc’d Natural Knowledge. Our 
Author has tollowd his fteps, averting nothing but 
what is evidently deduc’d (rom thofe Experiments, 
which he has carefully made, and faithfully related ; 
giving an exadt Account of the Weights, Meafures, 
lowers and Velocities, and other Circumftances of the 
Things he oblerv’d ; with fo plain a Defcription of his 
y^pparat:4S, and manner of making every Experiment 
and Obfervation, that as his Confequences are'juftly 
and eafily drawm, fo his Premiles or Fads may be 
judg’d of by any Body that will be at the Pams to 
.make the Experiments, which are molt of them very' 
eafy and fimple. 
His Account of every Thing is written in fuch an 
intelligible manner, that the inquifitive Reader is capa- 
ble ot underftanding it, without being puzzled .with 
perplex’d Calculations and complex Experiments ; 
which Authors have fometimes contriv’d, in order 
to be admir’d for thofe Things, which they them- 
felves found out either by mere chance, or with 
very little Labour. He has illuftrated, and put pafl: 
all Doubt, feveral Truths mention’d in Sir Ifaac 
Newtons Queries; which tho’ believ’d- by fome of 
our Eminent Philofophers, w’ere call’d in queftion by 
others of an inferiour Clafs, who were not acquainted 
with thofe Fads and Experiments upon which Sir 
Ifaac Newton bad built thofe Queries. 
But not to detain my Reader too long in general 
Remarks, I proceed to give a fhort Account of each 
Chapter of our ingenious and indefatigable Philofo- 
pher’s Book,
