Mr. H. F. Newall 



Briggs and Mrs. Newall for the exposures they had to make with 

 their respective instruments for the reappearing flash. 



These two observations were recorded in terms of the metronome 

 beats, and were connected with the chronometer readings by my noting 

 on the chronometer the instant at which the last call of the count with 

 the metronome was made by the time-keeper. 



The metronome was adjusted to beat seconds the night before the 

 eclipse, and as set it lost one beat in 6 minutes. It was tested about 

 a quarter of an hour before the eclipse, and again after the eclipse, and 

 was found in several trials to lose between one and two beats in 

 6 minutes. 



The photographs of the disappearing and reappearing crescents 

 afford a check on these signals called both by Dr. Wallace and myself, 

 but the discussion is not yet completed.
