Prof. E. Loomis on the Aurora of 1859. 83 
a Persei. No streamers or fluctuations of light were observed. 
By 10 p. M. the cloud bank had disappeared, the auroral light 
having disappeared previously. 
Sept. 8d. The entire day was clear; and at 4 P.M. I went 
on board a steamer for Syra. From 74-8 P. M., near the island 
Egina I saw in the north and northwest the carmine red light of 
an aurora. From 93-10} p. M., near Cape Sunium, a faint trace 
of the aurora was still seen; but no dark segment, streamers or 
fluctuations of light. 
1. Observations at Camp Simeahmoo, Washington Territory, (lat. 
49°, long. 122° 30’ W.), by ARCHIBALD CAMPBELL, Commis- 
seoner of N. W. Boundary Survey. 
At 8p. m. Aug. 28, 1859, a diffused light, without definite 
form, was observed a little east of north, covering about one- 
fourth of the heavens, which gradually increased to the west, 
sending across from east to west an arch of a whitish color, the 
arch itself being much brighter than the circumjacent light. 
This arch remained visible until2 A.M. At 95 25™ p, M, strongly 
Visible at 2h a. M., and probably remained so until daylight, 
Which at that season, in this latitude, occurs not long after that 
me. This arch was situated very little, if any, to the south. 
and did not move either to the west or east. At midnight, the 
arometer stood at 30°13; external thermometer 64° F 
9 August 29th a faint diffused light was seen in the north at 
still Visible at midni cht, No observations were made after mid- 
Might. There was no exhibition of the auroral light at this 
from Aug. 31st to Sept. 4th.
