Capt. Parry and Lieut. Foster’s 
more or less clue to the position or influence of the sun, and 
probably of the moon, on the terrestrial magnetic sphere ; 
but the particular laws of this influence is a question of great 
delicacy, and of intricate research, and will be best left to the 
investigations of those who are theoretically conversant with 
these subjects.

Note. The registered temperatures, throughout these observations, are according 
to Fahrenheit’s scale, and are all below zero, in those columns that have the sign 
minus ( — ) only, placed at the top, and above zero in those that have the sign 
plus (+) inserted in like manner. Those columns, however, at the top of which, 
these signs appear thus, ( qp ) contain observations, both below, and above zero, 
which are pointed out, by their respective signs, being prefixed to the several 
observations of each denomination.
