BOMBAY GEOGRAPHICAL SOCIETY. Ixxix
tal deviation, also the bar of ordinary hard iron I hammered until it
became magnetic, the polarity got shaken down from change of alti
tude, clearly showing that compasses corrected for semi-circular devia
tion by magnets are not infallible, but rather should he dealt with
cautiously when there is much change of latitude. Much could be said
on this subject, but it would be superfluous ; tbe science of magnetism
and local deviation having been so well handled by the first men of the
day.
You will see a correction in the last but one column of the observa
tions, it is so difficult to get the needle at a distance from the bar of
soft iron, so that the means of the four deflections will exactly equal
the magnetic dip.
I am, dear Sir, very faithfully yours,
T. Wherland.
P-S .—I s'endyou two photographs done very hurriedly.
Lieutenant Wherland’s Paper, “ A description of a Magnetimeter, by
which the Magnetic Dip is determined from the horizontal deflection
of a magnetic needle produced by terrestrial induction in a bar of soft
iron,” having been read, the Secretary laid before the Society a drawing
and two photographs sent by the Author. A vote of thanks was then
unanimously passed to Lieutenant "Wherland for his very valuable
and interesting communication, as also to His Excellency the Governor.
The business of the Monthly Meeting having thus been brought to
a conclusion, that of the Annual Meeting was taken up. The Minutes
of the last Annual Meeting were read.

declared the Office-bearers for the ensuing year: —
