there
if one were to adopt the assumption of an unobstructed polar basin.

Taking various facts into consideration, it would seem that an
obstruction (land, islands, or shoals) containing nearly half a million
square statute miles probably exists. That one corner lies north of
Bennett Island; another, north of Point Barrow; another, near Banks Land
and Prince Patrick Island; and another, at or near Crocker Land.

METEOROLOGY.--Regular hourly observations of the thermometer and
barometer were carried on day and night by the tide observers.

A brief resume of the results obtained is given below, together with a
few taken from the Report of the Proceedings of the U. S. Expedition to
Lady Franklin Bay by Lieutenant (now General) A. W. Greely.
