Error of chronometer found from altitudes of the sun, taken by Professor Mohn on the 9th and 10th of July, 1878.1 Declination. 1878. July 9. in the afternoon, we determined the azimuth of the church spire,- observing with the pocket- chronometer, for which the error on local apparent time was found to be 51m 20/4. On the 10th of July, 12 35 p. m, I determined the declination. 1 H. Mohn. Astr. Ohs. Side 12—14. H. Mohn. Astronomical Observations, p. 12—14.
