29. An Aurora was vifible at the horizon, extending from 
north-weft to nearly north-eaft. The whole arc, included 
within thofe limits to about 12° altitude, quite luminous. 
At 7* 20’, the ufual dufky appearance commenced at the hori- 
zon, and increafed till it became about 15° altitude. Light pro- 
_ ceeded from the upper part, notas from the periphery of aregu- 
lar arc, but from different heights.  Striz, frequent and difcon- 
nected, often appearing like rare white luminous clouds, varying 
their pofition and continually rifing, till 7* 50’ they reached the 
zenith. Striz more prevalent, pafling thezenith. At8^-, appeared 
a detached bright Auroral cloud in the fouth-eaft, within about 
30° of the horizon.— Another long fimilar cloud in the fouth- 
weft, paffing fwiftly downward to the fame diftance from the ho- 
rizon ;—thence, with a quick motion, weftward ;—then vibrat- 
ed from ait to weft in an arc of feveral degrees. Each Auroral 
cloud frequently difappeared inan inffant, then revived with equal, 
or faperior, luftre.— Thus they continued a few minutes, and 
then entirely vanifhed. "The ftriz, which were hitherto frequent 
and brifk, tho’ irregular, appeared to colle& at about 5° fouth of 
the zenith, and there formed a large body of light —Soon fuc- 
ceeded new thootings of ftria,—ftrong and regular ; and below 
them, a frequent flafhing of light. Between the ftriz and lu- 
minous glades was the fame dufky appeararice, as in the cloud 
near'the horizon. At 8^ 15%, a corona formed at about 3°
