    SECTION SEVENTH. Observations on the Winds. 1 nave before observed, that my observations on the winds refer them all to 8 equidistant points of the compass, and to 5 degrees of strength, marked 0, 1, 2, 3 and 4, respectively. Mr. CrostHwaiteE has referred them to 32, or the whole number of points, and to 12 degrees of strength; but I have reduced his observations to agree with my own, in order to prepare the following table of comparison. The observations at both places were made three times each day, namely, morning, noon and even- ing. It may be observed, that the high winds do not in general differ materially, either in strength or direction, at Kendal and Keswick, as might be ex- pected from the proximity of the places ; but when the wind is moderate, there is often a difference in direction ; probably the mountainous situations of the places may have some influence in this last case. Here follow Tables containing the number of observations on the winds each year, in all the different directions, at both places.
