 Latitiule, 44° 51' 49" N. 

 Directors : J. Palisa, 187L\ 

 R. MiJLLER, 1880.

Founded in 1872. 



The observatory at Tola has grown out of the okl marine observatory 

 at Venice, whicli, after the campaign of 1848, was at first removed to 

 Trieste, and from there to Pohi in the year 18GG. The observatory was 

 naturally used chiefly as a "chronometer depot." That meteorological, 

 and later magnetic observations were taken there was owing to the 

 exertions of the director and to the sagacity of the leading marine cen- 

 tral stations. 



The regular meteorological records at Pola began in xVugust, 18G4, 

 and were continued in the marine barracks !)y oflicers and cadets at 

 an altitude of 30.5 meters till February 7, 18GG, after which they were 

 taken in charge by the marine observatory, which had Just been moved 

 hero from Trieste. 



The observatory has paid particular attention to astronomy only un- 

 der Mr. J. Palisa's direction. I\Ir. J. Palisa has discovered at this ob- 

 servatory twenty-three small planets, and his brother, Mr. A. Palisa, 

 one (5omet. Since his call to Vienna nothing has been done in addition 

 to the regular time determinations but to fix the position of occasional 

 comets and small planets. We have at our disposal the following astro- 

 nomical instruments: 



One meridian, by Trougiiton & Simms, with G-inch object glass, of 

 G-foot focal distance, and two cirnles of 0.0 meter diameter. 



One refractor, with Ginch object glass, of 7-foot focal distance, ob- 

 jective by Steiniieil. 



One brachytelescope, by Fritsch, Vienna, with 12-inch glass. 



Two transportable comet-seekers. 



Four fixed telescopes, by Messrs. Frauniiofer and Plossel. 



Four i^enduluui clocks, among them a stationary pendulum, by 

 Knoblich in Hamburg, as a normal clock. 



One chronograph, by Hirr. 



Several })ortable universal instruments and theodoliths. 



It is intended to sell the brachytelescope, which was procured only 

 to observe the last transit of Venus, and which has too little si)ace in 

 its cupola, auil to instiill in its place the great comet-seeker in the way 

 invented by Villarceau. Beginning with the year 1885, the astro- 

 nomical observations are (o be taken up in a regular manner, and ob- 

 servations will be made particularly on the planets ; later also the sun
