resulting is 35-i-° north ; but with the obliquity allowed by Hipparchus, it will 

 be found less than 35". 



This I say, only to obviate any objection that may be made by P. Souciet to 

 the foregoing argument; though if he please to examine it, he will find that an 

 error of a degree in the assumed latitude, will by no means invalidate the proof 

 here given, that this first star of Aries could be no other than the middle star in 

 Lino Boreo Piscium, marked » by Bayer.

Jan. 4, 1727, appeared a luminous arcli, which extended from n. e. to west. 

 The streams all moved westward. 



Jan. 5, exhibited something of the same nature, but hardly enough for obser 

 vation, and yet this very night the appearances were more remarkable in some 

 parts of the kingdom than those of Oct. 8, 



March 2, between 7 and 8, there was an arch on a black basis as before, 

 extending from n. e. tow. Its height variable, pyramidal streams of greenish 

 light moving westward. 



March 3, the appearances this night were so extraordinary, that they would 

 require a long description; but I shall chiefly take notice of such particulars as 

 differed from those of Oct. 8. 



1. That instead of one luminous arch in the north, here were two, and 

 sometimes three, one above another. They were distinct enough from each 

 other in their upper parts, but blended together towards the horizon. 2. Several 

 of the more permanent streams were bent, at times, into irregular arches of 

 different curvatures and positions. 3. The flashing streams from the east 

 sometimes nrtet with those from the west, and so formed continued arches, of a 

 pale colour, which quickly broke and vanished. No colouring followed on the 

 mixture of these streams. 4. The streams of this kind moved mostly south- 

 ward, but not to any certain point; for they were inclined to the horizon at 

 all degrees between 5, or less, and QO. There was sometimes such a strange 

 irregularity in their motions as can hardly be described; for the places from 

 whence the flashings were directed seemed to vary every moment. 



N. B. Aristotle has given an imperfect account of some of these meteors.

This began about 7 o'clock at night, Jan. 5, 1727. From the northern 

 parts arose several streams of light, as if from behind a black cloud. They
