Remarks on the preceding Observations. 
1. In comparing the results obtained for the value of the Magnetic Dip at any station 
with those formerly determined at the same place, I assume, in default of any evidence 
to the contrary, that ail the observations are equally trustworthy ; also that where the 
mean has been taken between two or more observations at the same place, made at 
different times, that the mean value of the dip so deduced corresponds to the mean of 
the times of observation considered as a mean epoch. The following results, however, 
are offered only as approximations. 
2. Observations at Malta on Dec. 20, 1861, or 1861-97. — At the same spot of obser- 
vation, with the same instrument and needles, the dip was found to be 62° 17'* 3 N.
