cusp, but a considerable space, between 25 and 50 degrees from the 
portion of the circumference next beyond toward the right, whence it 
gradually narrowed t mere faint line of light before mentioned. 
These observations were made between half past 11 and half past 
1 o'clock. 
At 2h 15m p.M., the planet was readily found with a portable 5 foot 
Clark telescope of 4% inches aperture, by taking a position in the shadow 
of a chimney some 50 or 60 feet distant. The complete ring, and the 
faint portion of the crescent proper, just described, were both distinctly 
seen —better, in fact, than with the equatorial, except in the cases men- 
tioned, when the sun was intercepted by a passing cloud. 
ations were prevented on the 18th. On the 14th, at noon, the 
visible cusps extended full 50° beyond a semicircle, but no irregularity in 
rightness was noticed, as on the 12th. Onthe 15th, the cusps had re- 
ceded to 30°, and on the 18th, to 22°, beyond a semicircle. 
These observations have a direct and obvious bearing upon the ques- 
tion of the atmosphere of Venus. 
The powers used were from 80 to 200 on the Equatorial, and 90 on 
the smaller telescope. 
@ measurements, a position-micrometer by Dollond was em- 
ployed. C. 8.
