the motion of diurnal revolution westward, and it was to be seen about the 

 second hour of the night; for then it was demersed in the mists of the 

 horizon. 



Not far from its pointed end eastward, a star appeared, equal to the brightest 

 of the fourth magnitude, almost in the same place where was observed the 

 comet of 1664, December 31; which star was not then seen, nor at other 

 times elsewhere, nor is described in any catalogue, or any globe or map ; which 

 therefore he deems to be a new one, that is, of new appearance. 



March 11, in the evening, the horizon was in the west overcast with thin 

 clouds ; among which after one hour of the night, there was seen a brightness 

 in the Whale, at least for half an hour, which was very like the splendour of 

 Venus, likewise veiled by thin clouds. 



March 12, at night, the lower parts of the heavens in the west were clouded, 

 and when the great Dog-star was in the mid-heaven, the same tail appeared 

 again. It passed through the star in Eridanus which Bayer calls the 13th, 

 and left to the southward the 14th, where it terminated March 10. Being by 

 the imagination drawn out to about three degrees and further, it tended to that 

 southern star which precedes the ear of Lepus. It was therefore more norther- 

 ly than the day before yesterday, and more easterly ; and it also reached to the 

 opposite part of the sun. The apparent part of the train reached out in length 

 about 32 degrees. 



So far the Italian relation; the following is that from Lisbon. 



March 5, N. S. Forasmuch as it seems to follow the regular course of the 

 sun, and sets few hours after it, there could hitherto be taken no considerable 

 observations of it. The body is not seen, because it remains hid in the horizon. 

 Its train is of a stupendous length, extended in appearance over almost the 4th 

 part of the visible heaven, from west to east ; its apparent breadth is of a good 

 palm, and its splendour very great, but it lasts only a few hours. 



Several letters written from France also mention its having been seen in 

 several parts of that kingdom, as at Lyons, Tholouse, Toulon, but not at Paris ; 

 no more than it hath been observed at London, or in any other part of England 

 yet heard of.
