1° 15' E., 0° 05' E., 1° 28' E., a very irregular arch 

 S.W. to E., at an angle of 45° : 0° 20' E., 0° 40' W.,

1° 10' W., luminous appearances generally diffused in 

 patches : 0° 30' W., bright at W.S.W. : 1° 00' E., a 

 concentrated mass at the zenith, motion southerly to the 

 horizon : 0° 50' E., 00° 00', the mass travelling south : 

 0° 20' E., 0° 10' W., 0° 20' E., 0° 10' W., 0° 25' E., 

 0° 08' W., 0° 20' E., 0° 28' W., faint, no motion :

 mass W.S.W. : 0° 50' E., when it was stationary five 

 seconds, and then moved slowly to 0° 40' E., 0° 50' E., 

 stationary five seconds, 0° 30' E. ? 0° 45' E., 0° 30' E., 

 0° 50' E., luminous appearance S. S. E. : 0° 28' E., 

 0° 12' W., luminous appearance from S. S.E. to E.S.E., 

 at an angle of 15°: 0° 05' E., 0° 35' E., 0° 15' E., 

 0° 40' E., 0° 50' E., 0° 40' E., 0° 55' E., 0° 40' E., 

 1° 00' E., light appearances from W. to N. : overcast ; 

 0° 30' E., 0° 40' E., 0° 20' E., 0° 30' E., 0° 05' E., 

 0° 25' E., 0° 20' E. Here I finished, and, on going out, 

 found the sky overcast, though some few stars were just 

 visible. The aurora was then so faint, that the feeble 

 light from a lantern with one pane of glass prevented 

 my seeing it ; but, as the needle was still in motion, I 

 naturally conceived there must be some cause for it, and 

 having concealed the light by placing the lantern 

 under my cloak, I could then barely make out a very 

 filmy arch at S.W., which, however, soon vanished. 

 The temperature outside was — 14°, inside — 4° ; calm 

 and overcast.
