( 402 ) 
+ 5".8 and as mean error of the final result +1".8. We must 
also take into account however the error made in determining the 
index correction, which influences all the observations equally. If 
we assume that for this determination 5 pointings were made 
(compare above) and accordingly take the mean value of its error 
to be + 5".8 XY ¥/; = + 2".6, the total mean error of the result 
becomes + 3".2. | 
Moreover, as the observations are not arranged symmetrically 
with respect to the meridian, an error in the correction of the chrono- 
meter also influences the final result. Probably this error is not 
large, as the rate of the chronometer was pretty regular in the 
period considered. Also the results from the first and the last pair 
of observations, viz. 58".3 and 58".6, agree well inter se. An error 
in the chronometer correction of 2s would resuit in a variation of 
3”.5 in the latitude. 
2. Circummeridian altitudes of the sun on May 14, 1894. 
The observations were reduced in the same way as those of 
May 10, 1893. The sun’s places ete. were now taken from the 
Nautical Almanac; they are based on the same elements and values 
as those of the Conn. d. T. The following corrections and daily 
rates of the chronometer were found: 
Jan. 12 1894 © + 43m 44s76 
— 0s80 
April 26 + 42 21.30 
— 0.99 
May 22 w + 41 55.60 
— 9.01 
July 13 + 40 11.20 
For the time of the observations and the used part of the sextant 
we find: 
Corr. of the chronometer + 42m 3s6 
Index correction sextant — 1/50" 
Correction for error of graduation —+ 25! 
Temperature 27e 
Barometer 760 mM. 
Mean loc. time of transit of sun, 7’ 11h 56m 9s4. 
Hour angle of maximum altitude, 4 — 4s4 
Declination of the sun for 7+-¢, + 18° 41/10"1
