Mr. E. W. Maunder. 



Captain Eobertson was not present at the Royal Alfred Observatory, 

 but observed the eclipse from the deck of his ship, ss. " Ugina," of the 

 British India Steam Navigation Company, in Port Louis harbour, 

 6| miles S.W. by W. of the Observatory. 



An accident prevented Mr. Claxton from observing the second and 

 third contacts. Mr. Claxton and myself watched the contacts 011 the 

 ground-glass screens of our respective cameras. 



Times of the 10-sccond Bells. The times of the 10-second bells of the 

 eclipse clock which was one of the clocks used by the late Sir G. B. 

 Airy, K.C.B., in the Harton Colliery experiment were recorded by 

 Lieutenant F. W. Robertson, R.E., with the chronometer Kullberg 

 3400, that chronometer being l m O4 fast. 



Staff-Sergeant R. M. Smith called out the numbers of the bells as 

 each rang. 



Photographs of the Corona. These were taken on three different 

 scales ; the first on a scale of 8 inches to the Moon's diameter, to show 

 the prominences and lowest corona ; the second on a scale of 

 2'4 inches, to show the general structure of the corona; the third on a 

 scale of 0'3 inch, to show the coronal streamers to the greatest possible 

 extension. The aperture employed in each case was the same, viz., 

 4 inches, and the light-gathering powers on the plate of the three 

 instruments were nearly in the proportion of 1, 11, and 700.
