the sun rises on that part of the moons
surface.
Prof. Tromholt, Norwegian invest

The famous American opticians, Al
van Clark q Sons, of Cambridge, Mass,
have nearly completed the leHs for the
great telescope ordered by the Russian
Government for the observatory at Pull

now been in progress for year. The
telescope will be forty-five feet lorg, an.
the object glass is thirty inches in diam

the emiuGnt astronomer at Pulkova can
view the heavens through tue greatest re-
