a mean Velocity, between the fwiftcft and the flowed-, 
-it expreflcs, in the bed manner I can think of, the 
apparent Velocity of its Motion. 
The narrow luminous Streak remained very diftind 
after the Globe was gone j and gave a fair Oppor- 
tunity for taking the Elevation of this Phenomenon 
above the Horizon, at the Beginning and End of its 
Motion, &c. .had there been proper Inflrumcnts 
ready at hand : This not being the Cafe, I guefled the 
Elevation of the Globe, when it firft appeared, was 
near 30°' But forne Days after, being exadly in the 
fame Situation. as when I faw this Meteor, I took the 
Elevation of a fmall Cloud, which appeared to be in 
the fame Place, with a Quadrant of Two Feet Radius, 
and found it to be but 20°* This luminous Trad, or 
Path, feemed a Right Line, not quite parallel, but a 
little inclined to the Plane of the Horizon, viz. 
higheft towards the Eaft. It was at firft very narrow, 
and pointed at each Extremity ; but foon grew broader, 
and within 20 Minutes after the Appearance, which 
was the laft time I faw any thing of this Affair, it 
appeared exadly like a long bright rare Cloud, dif- 
continued in two Places, above three times its firft 
Breadth, and a little more inclined to, and elevated 
above the Horizon, than it was immediately after 
the Motion of the Globe.
