4. Eclipse of the Sun, May 26, 1854, at Yale College, (Lat. 41° 18! 
to inspire high hopes of a most favorable time fur observing the eclipse. 
ut by noon a strong northwesterly wind began to bring up ridges of 
cumulus clouds which, as the time of the eclipse drew near, left only 
o'clock, after which the view was unobstructed 
The end was closely observed by Mr. Bradley with a power of 80 
and by Mr. Lyman with 110, but the limb, being now near the horizon, 
was so broken and wavy that the instant of last contact could not be 
determined within several seconds. The time fixed upon was 6h. 42m. 
19s. This is probably within from 5 to 8 seconds of the truth. 
yman remarks, that with the Clark Telescope (aperture 9 
inches) the moon’s limb during the early part of the eclipse, was well 
defined, the lunar mountains being projected with great distinctness 
the sun’s disk. Two or three times near the middle of the eclipse, the 
extreme points of the cusps were observed to be momentarily cut of 
by projecting mountains. No other important physical phenomena 
were noticed by him, though the cusps and limbs of the sun and moon 
were carefully watched at frequent intervals. Mr. Newton could detect 
no signs of polarization with a double image prism. : 
Professor Olmsted occupied himself with the meteorological instrl- 
ments, and the general aspects of the earth and y- He was fayora-

11 digits) the shadows became less deep, the color of the grass and 
trees, now at the height of their summer verdure, wore an increasing 
olive hue, and a sublime and strange appearance invested all things
