Founded in 1872.
The observatory at Pola has grown out of the old marine observatoryat Venice, which, after the campaign of 1848, was at first removed toTrieste, and from there to Pola in the year I860 . The observatory wasnaturally used chiefly as a “chronometer depot.” That meteorological,and later magnetic observations were taken there was owing to theexertions of the director and to the sagacity of the leading marine cen-tral stations.
The regular meteorological records at Pola began in August, 1804,and were continued in the marine barracks by officers and cadets atan altitude of 20.5 meters till February 7, 1860, after which they weretaken in charge by the marine observatory, which had just been movedhere from Trieste .
The observatory has paid particular attention to astronomy only un-der Mr. J. Palisa’s direction. Mr. J. Palisa has discovered at this ob-servatory twenty-three small planets, and his brother, Mr. A. Palisa,one comet. Since his call to Vienna nothing has been done in additionto the regular time determinations but to fix the position of occasionalcomets and small planets. We have at our disposal the following astro-nomical instruments:
One meridian, by Trougiiton & Simms, with 0-inch object glass, of0-foot focal distance, and two circles of 0.9 meter diameter.
One refractor, with 6-inch object glass, of 7-foot focal distance, ob-jective by Steiniieil.
One bracliytelescope, by Fritscii, Vienna , with 12-inch glass.
Two transportable comet-seekers.
Four fixed telescopes, by Messrs. Fraunhofer and Plossel.
Four pendulum clocks, among them a stationary pendulum, byKnoblich in Hamburg, as a normal clock.
One chronograph, by Hipp.
Several portable universal instruments and theodoliths.
It is intended to sell the bracliytelescope, which was procured onlyto observe the last transit of Venus, and which has too little space inits cupola, and to install in its place the great comet-seeker in the wayinvented by Villarceau. Beginning with the year 1885, the astro-nomical observations arc to be taken up in a regular manner, and ob-servations will be made particularly on the planets; later also the sun
