for two short periods only. On six occasions, two of them 

 covering three days each, it fell below 29.50. 



The records from June 27 to July 15, inclusive, are 

 from the ship's aneroid, which was neither compensated nor 

 tested, and which reads from i-io to 3-10 lower than the 

 other. The records for these dates are therefore inclosed in 

 parentheses in the table. Records after July 15 are from a 

 far more reliable compensated aneroid (Thaxter, Boston), 

 reading to 5,000 feet. The latter was compared under widely 

 varying pressures with the standard mercurial at Cambridge, 

 Mass.. from which it was found to vary but very slightly. It 

 was also subjected to frequent tests by Dr. Daly during the 

 trip, by means of comparisons with measured heights and 

 with other barometers, and found to possess a high degree 

 of accuracy.
