It is interesting to compare these figures with those given by 

 Mr. Eliot in his meteorological note prepared in connection with the 

 eclipse. No data are given for Pulgaon, but the conditions are 

 practically the same as those found at the two nearest stations for 

 which the figures are given, namely Akola and Nagpur. 



We have then 





The figures exhibit the futility of selecting an eclipse station 011 

 meteorological data only.

II. Totality at Pulgaon. 

 By Captain Hills and H. F. Newall. 



The preparations for totality as regards the instruction and drill- 

 ing of the assistants calls for little mention. The skilled native 

 assistants, provided by the kindness of the Survey or- General, were 

 thoroughly accustomed to observing work, and the preparations and 

 preliminary drills proceeded with the utmost smoothness. 



The two men selected as timekeepers were instructed to call out 

 the seconds from the beats of a metronome, which had been pre- 

 viously carefully rated. 



The signal for the beginning of totality was given by Captain 

 Lenox Conyngham who was making the exposures with the double 

 tube camera, but it was also necessary for the spectroscopic work to 

 get a signal at some definite time before totality which was accom- 

 plished by the following method : 



The length of the diminishing crescent of the sun was calculated 

 for 15 seconds before totality. The observer in charge of the double 

 tube camera watched the image on his ground glass and gave a 

 signal when the crescent had arrived at the calculated length. The 

 actual interval between the 15 second signal and the beginning of 

 totality was 13 seconds.
