REPORT ON THE STATE CABINET. 



For these observations was tlie index error = — 5' 17" (to be added 

 algebraically), determined by contact of the limbs, twice at the begin- 

 ning and twice at the close, with the same sun-glasses. Moreover has 

 been assumed: the sun's declination = -|- 8° 53' 50". 5, its semi-diameter 

 ter = 15' 53", parallax = 7". Not being provided with barometer 

 and thermometer, mean refraction only could be applied ; however, 

 by combining morning and afternoon observations, the neglect of the 

 meteorological instruments cannot affect but the second order. After 

 the more correct value for the latitude of the place had been obtained, 

 it became of necessity to repeat the computation of the hour angle 

 (apparent time in arc) ; and consequently all the reductions have been 

 made in double. By taking the mean of the last column, we get the 

 correction of the chronometer to sidereal time of the place 



August 30, 6" 57™ 38^ chron. AC = — 17™ 57= 14, with the probable error ± 0^51, 

 as the final result from the above set of altitudes.
