are nearer, and the Agitation of the Fluid Sphe- 

 roid revolving about a greater Circle, is greater; 

 befides, the Centrifugal Force (arifing from the 

 Diurnal Rotation) is there greateft of all. This 

 will ftill be more confiderable about the New 

 and Full Moons happening at thefe times, for 

 the Reafbns juft now mentioned And the leaft 

 Attraction will be about the Quadratures of thefe 

 Lunar Months, becaufe the Declination of the 

 Moon from the Equator is then greateft. * The 

 different diftances of the Moon in her Periggeum 

 and Apoggeum, are the Realbn that thefe full 

 changes fall out a little before the Vernal, and 

 after the Autumnal Equinox. Now the Inverfe 

 of all this happens when the Luminaries are in 

 the Solftitial Circles. Laftly, In the fame Pa- 

 rallel, when the Moon's Declination is towards 

 the Elevated Pole, the Attraction is ftrongeft when 

 the Moon is in that Places Meridian, and weak- 

 eft when (he is in the Oppofite Places Meridian : 

 The contrary happens in the Oppofite Parallel ; 

 by reafbn of the Spheroidal Figure of the Earth 

 and its Atmofphere. 



Whatever has been faid on this Head, is no 

 more that applying what Sir Ifaac Newton has De- 

 monftrated of the Sea to cur Atmofphere ; and 

 it is needlefs to fhewhow neceffarily thole Appear* 

 ances, juft now mentioned, of Winds, at the 

 Stated Times, &c. muft happen hereupon. It 

 will be of more ufe to confider the Propor- 

 tion of the Forces of the two Luminaries upon 

 the Air, to that which they have upon the Wa« 

 ter of our Globe ; that it may the more plainly 

 appear what Influence the Alterations hereby 

 made, muft have upon the Animal Body,
