See we not plainly that obedience of creatures...

It is a fudden and violent ftorm of wind, rain, thunder and lightning, attended with a furious fwelling of the feas, and fometimes with an earthquake; in fhort, with every circumftance which the elements can a'fTemble, that is terrible and deftructive.

222 ページ - ... the name of Comets has been given. They are distinguished from the other celestial bodies, by their ruddy appearance, and by a long train of light, called the tail, which sometimes extends over a considerable portion of the heavens, and which is so transparent that the stars may be seen through it. The tail is always directed to that part of the heavens which is opposite to the sun, and increases in size as it approaches him, and is again gradually diminished.

Of all the prejudices which philosophy contradicts, I believe there is none so general as that the earth keeps its place unmoved.

Those who have any tincture of education are not now in danger of being held by it, but they find at first a reluctance to believe that there are antipodes ; that the earth is spherical, and turns round its...
