    from the north to the east their distance is 3, 4, or 5 miles. St. George’s Channel bears SW. and the high water at spring comes up the river to within 6 miles of the town, but low water is at a great distance. The town may be 25 yards above the level of the sea.—Keswick is situate in lat. 54° 33’ N. long. 3° 3’ W.; it is well known to be in the centre of a mountainous country, and some of the highest mountains in the north of England are in its neighbourhood. It is 16 miles from the Channel, and perhaps about 45 yards above its level.} The observations at Kendal were made by the author, three times each day, namely, betwixt 6 and 8 o’clock in the morning, at noon, and at 8 or 10 in the evening.—Those at Keswick were likewise made three times each day, the morning and noon ob- servations about the same time as at Kendal, but the evening observations were made at 4 or 5 in the winter, and 6 in the summer; the observer was Mr. Crosthwaite, a gentleman, who, besides his attention to meteorology, has been for several years past assiduously furnishing a museum, for the entertainment of the tourists, at present consisting of a great variety of natural and artificial productions from every quarter of the globe, fossils, plants, &c. and he has also made accurate surveys of the lakes. The observations at London are taken from the Philosophical Transactions of the Royal Society, being those made there by order of the president and council; they are made twice a day, namely at 7 A. M. (in December, January, and February at 8 A.M.) and at 2 P. M. | With respect to the barometers at Kendal and Keswick, the were both clear of air and moisture, and exhibited the electric light in the dark. The scales were both full inches, and there- fore the variations were somewhat greater than the observations denote them.—About =!, should have been allowed upon them. In the following account we have given the mean state of the barometers, at the respective places, for each month of the year, and likewise for the whole year, together with the highest + It may not be amiss to remind the young Tyro here, that the higher any place is above the level of the sea, the lower will the mean state of the barom- eter be at that place.
