1898 eclipse at Berar), received the plates, recorded the times, and also 

 exposed for 10 seconds the integral photometer. 



Mr. Lovett Henn, of Algiers, made the exposures with the grating for 

 Mr. Xewall. 



Mrs. Newall made observations of the atmospheric polarisation 

 during totality. 



At 15 seconds before totality, as shown by the diminishing crescent 

 of the sun, Professor Turner called " Stand by"; at totality, "Start": 

 when Mr. Wyles counted from the metronome steadily up to 80. 

 Totality lasted 64 or 65 seconds, and the extra 15 seconds was required 

 by Mr. Newall for exposures at the second " flash." The signals were 

 given with approximate correctness, though, by an oversight, no one 

 timed the interval between the "Stand by " and the " Start." 



The operations were rehearsed several times on the day before the 

 eclipse, and once or twice in dumb show on the actual day. It was not 

 found possible to arrange for rehearsals earlier ; but, with the exception 

 of the omission just noticed, everything went off at the time without a 

 hitch. 



10. Tlie Day of tlie Eclipse. Perfectly clear all day no anxiety. 

 The contacts were not observed by us with special care as we had much 

 else to do, and observations were being made by the staff of the 

 Observatory. M. Sy kindly supplied the following predictions and 

 observations :

Lamps were not needed during totality. 



Owing to an accident (a signal being lost through noise made by 

 others) the shadow was not observed. Major Kingsley Foster noticed 

 the " shadow bands " on the white surface of the " double tube " near 

 which he was stationed.

11. The Cameras. The double camera used at Fundium iu 1893 (by 

 Sergeant Kearney), and at Sahdol in 1898, was modified on the present 

 occasion. One of the 7 x 7-inch tubes contained, as before, the photo- 

 heliograph objective No. 2 of 4 inch aperture and 5 feet focal length, 

 with a Dallmeyer secondary magnifier of 7 inches focus placed
