Prof. A. D. BAcHE Of the Coast Survey presented an

observations for atmospheric pressure at an Rensse
laer HaIbor, North Greenland, made by the second
Crirpell expedition, under command OF Dr. r.. N.
Kane. u. s. n, during 1853, 1854 and 1852 obtained
from reduction and discussion by Charles A. Schott,
Assistant Coast Survey
Hourly observations Of the barometer were made
in the second Grnreu expedition, under command Oh
DR. Kane, the full discussion of which by Mr. Schott
is in the course OF publication in the Smithsocian con-
tributops TO knowledge. Tho period embraced IN the
discussion was from Sept. l. 1853 to June "a, 1852
The diurnal variation Of pressure was very percePI
bic but not 50 regular to deduce the Law entirely
satisfactorily from short series OF observations where
the range ot huctuati0n small. The usual ~ p H.
maximum Of the Northern Hemisphere was clearly
marked but the p. IN. minimum, SHOWN oy tne op'
servatiors at Van Rensselaer, harbor, occurred three
hours earlier than at mole southwardy stations. The
rapee was not one hundredth Of al inch
The barometer sto)d above the mean in January,
February, March, April and May, and below It in tue
other months. THE barometer stood highest in May
and lowest in September, the range being 2-nun-
