90 On the supposed Tides in the 
der to ascertain its regularity and succession. The result of 
these observations, which were necessarily brief, and defec- 
tive, is annexed ; very little satisfactory inference can be 
drawn from them, as no correspondent oo were 
made upon the courses of the moon, without which no cer- 
tain deductions can be made, as to the naiiiey of that eure 
et in producing this change. It will be observed, how 
that during three of the six days, in which the siusii atin 
were made, there was a flux and reflux, twice, notwithstan- 
are the wind prevailed, in the same course, during the day, 
flow were very sudden, and in that respect deviate from the 
general character of tides. It was seldom more than an 
hour, in attaining its height, and was generally as rapid in 
making the descent, though several hours would often inter- 
vene between the changes. 
Su a winter to be the most favorable time for 
making ce observations, when the superincumbent ice 
would ee destroy the influence of the winds, and shew 
the unassisted operations of the tide ; vo made inquiries, as to 
the appearance of it, during that season. One gentleman 
informed me that no tide was then ‘discernible: Another, 
ice. This difference of accounts, may, aps, be recon- 
ciled, by the probable difference in the ft of the ob- 
servation.
