Here it appears that the easterly and westerly points approach 
and recede from the north together , with only five exceptions, 
viz. May 6th, at 4 h 5 b and 6 h P. M. ; 7th, at 7 h 30“ A. M. 
and 9 h P. M. The direction of the deviation of the easterly 
point is minus till the middle of the day nearly regularly, and 
is plus, during the remainder, with some irregularities in the 
afternoon. Though the character of the deviation of the 
southerly point is somewhat ambiguous, as we have seen 
would be the case in this situation, if the changes of direction 
and of intensity counteracted each other’s effects, yet, with 
the exception of some irregularities, it agrees with that of 
the observations at the south, from the 20th to the 27th of 
April, the maxima being however rather later.
