Befides the waies the Ingenious Dr. Willie (of whofelofs we are 
already fenfiblej mentions, and all Peftilential particles of the 
Air 5 the Lungs might be difcompofed by the variation of the 
PreflTureof the Air,and thelmpotency of the internal torcfiftitjor 
theweakned Spring of the external, and Elatery of the internal 
Air. By thefc performances we may rationally apply this The- 
ory to particular Difeafes, and defcend to them , fince we know 
fomething a priori ; but ftill with refpeft to the Conftitution, 
Diet, Country, Education,&c. of the Patient. 
By the Germms EflTaies we may perceive the acknowledgment, 
our Neighbours make, or ought to make, of being awaken'd by 
the Englijh to thefe Difcoveries. 
I cannot underftand, why the Learned Dr. Moor ^ famous with 
mzi Cambridge ^ fliould reduce fo many effefts to any Principle 
diftinft from the fettled Laws of Nature and God's Providence, 
but that he is too much devoted to the Notions of the PUtonifls 
(as appears in all his Writings,) and other of the Ancients, that 
held the Sfforld animate ; and this Spirit of Nature to be the 
Soulor Deity of it: For never any fuppofed both God and this 
Spirit. This explication of efFefls is no more than to fay , 'tis 
produced by an Univerfal caufe, as the Sun hardens Clay , foftens 
Wax, &c« But me think?, he might have told us , hovp it afls , or 
what Namral means it ufes» 
Now to give youfome/>r^?w//2r«o«!f Obfervations as they occur 
to my memory: I have at Cambridge fbme of thofe Star-jloneSy 
Mr. L//?^rmentions in thefe Trafts 5 with fuch joynts , found in a 
Brook near Harborow in Leicejlerjhire. There are alfo fome 
Jhnnder-Jlmes lik^ the heads of Arrows, which being rub*d emit- 
ted a Sulphureous odour. Lately in Shrofjhire , where I found 
thefe Stones, I took notice of a Shell imprefling its fignatureon 
the Earth, which began to petrifie withinit and look flielly. And 
I may fuggeft the Inquiry, whether thofe Shells which are found 
in the ground, andfeemto argue the Sea was once there, are not 
fuch Geometrical efFefls of Nature, either by a Seminal principle 
from the Shells decaying, or thecffefts of the Accidental iropref- 
fions from fome Shells which came thither by accident. And this 
Doftrine might be muchilluftrated by fome paflTages in the Eflay 
of x^atOriginof Gems^ receiving a fignature when they and the 
Minerals
