    continuously for two months. Captain Pim, quoted by Dr.
    Warren, thus describes the Polar year:—
    "On the 16th of March the sun rises, preceded by a long
    dawn of forty-seven days, namely, from the 29th January, when
    the first glimmer of light appears. On the 25th of September
    the sun sets, and after a twilight of forty-eight days, namely, on
    the 13th November, darkness reigns supreme, so far as the sun
    is concerned, for seventy-six days, followed by one long period
    of light, the sun remaining above the horizon one hundred and
    ninety-four days. The year, therefore, is thus divided at the Pole:—
    194 days sun; 76 darkness; 47 days dawn; 48 twilight."*
    But other authorities assign a longer duration to the morning
    and evening twilight, and reduce the period of total darkness
    from 76 to 60 days, or only to two months. Which of these
    calculations is correct can be settled only by actual observation
    at the North Pole. It has been ascertained that this duration
    depends upon the powers of refraction and reflection of the
    atmosphere, and these are found to vary according to the tem-
    perature and other circumstances of the place. The Polar
    climate is at present extremely cold; but in the Inter-glacial
    epoch it was different, and this, by itself, would alter the dura-
    tion of the Polar dawn in inter-glacial times. But whatever the
    cause may be, so much is beyond doubt that at the Pole the
    twilight of the yearly morning and evening lingers on for
    several days. For even taking the lowest limit of 16°, the sun,
    in his course through the ecliptic, would take more than a
    month to reach the horizon from this point; and during
    all this time a perpetual twilight will prevail at the Pole. Long
    dawn and long evening twilight are, therefore, the principal
    factors in shortening the darkness of the Polar night and if we
