at the total solar Eclipse in 1882 377 



By 9-i9'5 i c.c. had passed, and between 9.21 and 9.29-5 

 5 c.c. passed. 



The observations made at this time are collected in Table I V. 

 In the first column is the apparent solar time of each obser- 

 vation, in the second column is the volume of distillate collected 

 at that time, in the third column is the mean time of collecting 

 each portion, in the fourth column is the date stated in minutes 

 after totality, in the fifth column is the average rate of distilla- 

 tion in c.c.'s per minute during the interval, and in the sixth 

 column is the percentage of the sun's disc exposed. 



The diagram Fig. 9 shows the progress of the eclipse and 

 the portions of the sun successively uncovered. 



From Table IV we see that when distillation has begun, 

 it increases at a much greater rate than does the exposed 

 sun's surface. This must be so in the early stages, because 

 we see that it is not till 27 minutes after totality and when 

 already 33 per cent, of the sun's surface has been uncovered 

 that the water in the boiler boils, and it takes 16 minutes
