NO. 6.] INTRODUCTION. CHRONOMETERS. XXI 



The observations have been calculated with the Besselian elements given 

 in the Connaissance des Temps, and the results have been combined as 

 follows : 



1 st contact, Htv Gr. M. T. = 42 m 12 s 

 2 nd [1] = 41 27 



Mean 41 49.5 



2nd _ [ 2 ] Hw _ Gr> M T. = 41 38 



Definitive mean =41 44 



On account of Mr. Scott-Hansen's remark about his observation of the 

 2 nd contact it was deemed reasonable to give it the same weight as the mean 

 of the two others. If the two notches which were estimated alike had been 

 exactly so, the first mean would be nearer the truth, but the difference is not 

 of any importance. 



1895 March 25 (March 26 on board). The circumstances of this eclipse 

 which took place about 6 in the afternoon were much less favorable than the 

 former. The greatest phase was only 0.045, and the limb of the very low 

 sun was so boiling, especially at 2 nd contact, that the observations were very 

 difficult. 



No stars were observed the same day, but altitudes of ij Ursse Majoris 

 and Cygni were taken the day before and the day after; the mean of the 

 results, which differ only 24" in latitude and 54" in time, was latitude 84 8' 22" 

 and Htv 5 h 58 m 51 s slow on Local Mean Time. 



The observers were SCOTT-HANSEN at the telescope and SVERDRUP at the 

 altazimuth. At 2 nd contact both observers took care to note, as nearly as 

 possible, the moment when the notch was apparently of the same magnitude 

 as at 1 st contact. The moments, reduced to Htv, were
