of the Night before: It continued till near 11. At 
8 h 56' p. m. exattly, fuch another Arch appear’d, 
very nearly of the fame Extent and Dire&ion, but 
not altogether fo broad or lucid. This at firft alfo 
palled between the two bright Stars of Gemini , but 
declin’d more and more to the Southward, till it 
was 2 or 3 Degrees to the South of Follux Its 
Weftern Limb, about 9, palled through the North 
Shoulder of Orion: It quite difappear’d about 10 or 
1 2 Minutes after. This had no Columns attach’d 
to it, as the former ; tho' it was fomewhat jagged 
and unequal towards the North near the Vertex.

29.9. The next Morning the Wind was SW b\V 1,
