Weft: Thefe were not of long Duration, but were fucceed- 
ed by others which appear’d and vaniftied again by 
turns, arifing from, and afcending up to Places in the 
Heavens, of very different Altitudes above the Hori- 
zon, From the time 1 began to view them, they con- 
tinued to afcend more and more copioufly, being pro-

wards the Weft and Eaft, and dire&ed always to the 
Heads of Gemini , till at length when they feem’d al-
