as yet been decided on, except that library, study, computing and 
sleeping rooms are to be attached to the main building, and that 
dwelling-houses, &c., will be close by, on a shelf of the hill lower 
down ; there is also to be “a large building for the accommoda- 
tion of the general public, which building will doubtless be rented 
as a hotel.” The main building will be about 70 feet in diameter, 
the foundation of stone and brick, the walls of iron and steel. 
Besides the large and the smaller equatorial, there will be a 
meridian circle and other instruments. 
A new observatory has been founded at Madison, Wisconsin, 
by Mr. Washburn. Professor Watson has left Ann Arbor to take 
charge of it. 
M. von Konkoly has published a volume of “ Beobachtungen 
angestellt am astro-physikalischen Observatorium zu O’Gyalla 
in Ungarn.” (Halle, 205 pp. and 6 plates, 4to.) It contains 
spectroscopic observations of bright stars (no measures), observa- 
tions of sun-spots, 1872-78, and observations of meteors. The 
chief instruments are a 103-inch silver-on-glass equatorial by 
Browning, and a 6-inch refractor by Merz. 
From the Breslau Observatory is published a 4to volume of 
“ Mittheilungen” by Dr. Galle, chiefly containing researches on 
the meteorology of Breslau, and on the geographical position of 
the observatory. The latter was arranged in 1790, in a tower on 
the roof of the University building, and its principal instruments 
are several repetition-circles and small altazimuths, a transit by 
Dollond (O.G. 24-inch diam.), and a heliometer by Frauenhofer, of 
3% feet focal length, and 2°8 inches aperture. (This instrument was 
used in China by the German “Venus Expedition.”) The volume 
contains biographical notices of the directors Jungnitz, Brandes, 
Scholtz, and Boguslawski, and the assistant Wilhelm Giinther. 
A volume of Cambridge Observations has been published, con- 
taining observations made during the years 1861-65.

The second volume of Oppolzer’s “ Lehrbuch zur Bahnbe- 
stimmung der Kometen und Planeten” has appeared in October 
last, nearly ten years after the first volume. Such a work was 
indeed a desideratum. Though no student of astronomy ought
