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
