The Reverend Mr. Pafchal to Mr. Ray- 



sir, r "-I 



THERE Teems to be throughout the Univerfe 

 a Mutual Contranitency between Parts Central 

 and Circumferential ; thofe emitting and propelling 

 outwards 3 thefe refilling and repelling inwards. Of 

 this I have three Inftances now in my Thoughts. 



1. In this, or any other Planetary Syftem the Sun 

 fends forth, chiefly by its Ecliptic Parts ^ and the 

 ambient fixed Stars in their refpe&ive iEthers, and ac- 

 cording to their Powers, give Bounds, and beat back, 

 from whence proceeds a Plenitude as abfolute and en- 

 tire, and ciofe, as the Nature of fuch a Fluid can ad- 

 mit of. 



2. In this, or any other Planet, the internal Solar 

 Matter inclofed in its Cortex^ moving rapidly about 

 its own Axis, continually tteams out moft dire&ly 

 and vigoroufly in the Equino&ial Parts : And the en- 

 compaffing JEther is always, according to its Power, 

 giving Limits to thofe Steams, and driving them back. 



3. In all thofe particular mixed -Bodies, made fo as 

 to fend outward, chiefly whatever Individuals in any 

 of the three Kingdoms of Nature, there is an internal 

 Principle, or Agent, caufing Effluvia to come forth : 

 And in the Atmofphere, in which they are, a Refi- 

 nance to thefe Motions outwards, fuitable to the Na- 

 ture and Motions of its Parts, and the Determinations 

 belonging to thofe Motions. 



Sir, I fancy, but with Submiflion to better Judg- 

 ments, that if thefe three were with Application and 

 Diligence look'd into, they might contribute fomc- 

 thing towards an Explication of fundry Phanomen& m 



Nature*
