Signals for Determination of Longitude, &c.—Continued. July 30, the breaks for the seconds of Salt Lake and Colorado Springs coincide. By measuring the differences where I find the full minute, I develop the fact that the Colorado Springs chronometer breaks 08.110 later than the Salt Lake break; therefore the mean of the signals sent from Salt Lake and received on the Colorado Springs chronograph is, 18h 48m 52.048. The same happens on August 2. The Colorado Springs chronometer is 08.095 later than the Salt Lake chronometer on the Colorado Springs chronograph; therefore the mean is, 18h 39m 78.626. |
