DETERMINATION OF THE LATITUDE BY OBSERVATION OF TRANSITS 
OF STARS ACROSS THE PRIME VERTICAL. 
In July, 1891, I determined the latitude of this Observatory 
by Bessel’s Method of Prime Vertical transits. The obser- 
vations were made with the 2,4-inch transit instrument, 
which was mounted on the pier of the altitude and azimuth 
instrument in the cone. Besides the transit instrument 
the Fauth sidereal clock and the chronograph were 
used. All these instruments have been described above. 
The clock, which had been running badly, was taken down 
and cleaned on July 13th, two days before the observations 
were commenced. Its correction was determined as fre-
