Prof. E. Loomis on the Aurora of 1859. 87 
At 10" 10™ p.m. the rays and arches disappeared and the 
northern sky seemed to be covered with a steady white light, 
with horizontal wavy bands of dark haze rolling up in quic 
succession, and vanishing as they attained an altitude of about 
60°, continuing until 10" 80™ p. m. and gradually fading away. 
ll. Observations at Fort Bridger, Utah Ter. (lat. 41° 14’, long. 
110° 83’), by KirtLey RyLanp, Assist. Surgeon U.S. Army. 
Sept. Ist, 1859, a brilliant aurora was seen at this place. It 
was first observed about 11 P.M. and attained its greatest bril- 
liancy before midnight. It extended from the northeastern ho- 
rizon to the southern horizon, and was in fact a Borealo- Austral 
Aurora. Generally the light assumed the form of spikes and 
bars, but high above the horizon in the northeastern sky was 
a large blotch or spot, whose diameter was perhaps three times 
that of the constellation Orion. This blotch was of a deep crim- 
son color, and remained for a considerable time unchanged in 
form, color or intensity, and faded gradually away. In the oth- 
er portions of the aurora the light appeared to spout from the 
horizon, in the shapes already cans frequently reaching the 
zenith, and was of great brilliancy. It appeared to flow gradu- 
ally from N.N.E. to the southern sky. 
12. Observations made at Cantonment Burgwin, New Memico (lat. 
36° 21', long. 105° 42’), by W. W. ANDERSON, Assist. Surgeon 
U.S. Army. 
A member of the guard mounted’ Sept. 1st observed a light 
Teflected from the clouds on that night about 10 P.M. as he was 
walking post, the clouds having gba just then thinned out 
or broken away a little. No other member of the guards from 
Aug. 28th to Sept. 5th saw anything unusual during the inter- 
vening nights. By reference to the Meteorological Register I 
find that the weather was cloudy during the whole time that the 
aurora was visible elsewhere. There was rain on the last four 
of us, by persons residing there, but was not observed with suf- 
ficient attention to enable them to answer any of your questions 
With accuracy. physician, Dr. Ferris, who arrived at Taos 
from Pike’s Peak during the fall, states that he was in the South 
of the heavens, The light was like a large fire in the distance,
