To the extreme ranges by this instrument, as noted in the tables, should be added the variations of level in the cistern, whiclr are as 1 in 40. It is, however, to the special variations of the barometer during extraordinary phases of weather that we must look for the most interesting and important generalizations; and these cannot find place in such a summary of observations as is now presented. It is important to the cause of science that a series of barometrical observations should be made at certain hours, daily, at several points in the frontier counties and in the centre of the State, and preserved for collation in the repository of the Regents of the University. A few cases of interest, of which a partial knowledge has been obtained, may here be adduced by way of example. The great storm of November 11th, 1835, which in its course from the interior of the continent, swept over the greater portion of the United States and Canada, if it possessed the general rotative character which is commonly exhibited by the storms of the sea-board, as most of'its phenomena would seem to indicate, then its centre of rotation must have passed through the basin of the great lakes and of the St. Lawrence, and the physical influences of _ the rotative action must have here produced the greatest degree of depression in the barometer, and this effect must have become lessened towards the sea coast of the middle states.
