The barometer also did not vary, the curve on the barograph 
sheet for several days before and after the eclipse showing a curve 
indicative of thunder. 
Owing to clouds the first contact of the Moon with the Sun 
could not be seen, the last contact, however, was seen particularly 
well, and notwithstanding the error in the Nautical Almanac as 
to the duration of the time of totality of the eclipse, the time of 
the last contact agrees well with the time given in the Nautical 
Almanac. The Nautical Almanac time of the last contact is 
4h 26™-6, and the time observed at Dunsink 45 26™ 35*7, this 
observation was made on the chronograph with the Dent sidereal 
time clock, the error of this clock was determined on the same night. 
Readings of Thermometers made during the Kelipse of May 28th,
