Magnifying Tower of Telefcopes, ot 



He is alfo feen to be accompanied with four moons, or fatd- 

 iites, revolving in certain periods : even their cclipfes, which 

 afford an excellent method for determining the longitude of 

 places on our earth, can be diftinftly fecn. Mars is obfer\-ed 

 to have fome fpots near one of his poles, by which he is 

 known to have a diurnal rotation round his axis. The beau- 

 tiful planet Venus, that now adorns our evening fkv, is ob- 

 fer\'ed to wax and wane like our moon; fometimes being 

 merely a crefcent, then horned like the moon only a few 

 days old, then gibbous, afterwards full ; exhibiting different 

 phafes like our moon, and thus affording an inconteftible 

 proof of the Newtonian fyftem of aftronomy, now univerfal- 

 ly adopted by men of fcience in every part of the world*. 



The planet Mercury, though butfeldom feen, yet deferves 

 our attention, as he more frequently than Venus paffes be- 

 twixt the fun and us, appearing like a patch upon the difc 

 of the fun, and thus, to thofe that know how to avail 

 themfelves of thefe phenomena, gives additional proof of 

 the truth of the prefont fyftem. The fplendid face of our 

 moon, in her various phafes, offers fo many fimilarities to 

 the earth which we inhabit, as leave but little room to doubt 

 flie is deftined for the fame grand end, an habitation for in- 



* The truth of this fyflem has been proved by innumerable obfervations 

 irsde with this excellent inftrument, by men every way qualified to judge, 

 v/ho with unwearied diligence, and without any bias or motive whatever 

 but a ftrong ^fire to fearch out the truth, h^ve examined and proved 

 every part of it, and fixed it upon too ftrong a bafis to be overturned of 

 refuted by the ignorant or intereftcd, who pretend to do fo without pof- 

 ferTing one (ingle qualification to enable them to form a proper judgment 

 in th:s matter, or a fmgie pretenfion but what is founded in the groficft 

 ignorance, accompanied with the moft. confummate afTurance. But enough 

 pf this at prefcnt. Perhaps at a future opportunity I may offer fome re- 

 tnarks upon, and throw together fome of the leading features of the New- 

 tonian fyftem, for the fake of thofe who, for want of better information, 

 arc- dnily duped out of their money by the Contemptible jargon of even the 

 moft ignorant and ftupiJ of mankind.
