Tue height of Kendal above the sea was set down 25 yards, by estimation only ; I have since found, by levelling with the barometer, that Stramongate bridge, at Kendal, is 46 yards above Levens bridge, to which the tide flows ; though it seems the survey for the intended canal makes the height less: I am not aware of any circumstance that could lead me into an error. Mr. Crostuwarre has lately determined, by le- velling with a very good theodolite, that Bassen- thwaite-lake is 70 yards above the level of the sea, and that Derwent-lake, which is 10 yards below his barometer, is 76 yards above the level of the sea; I make the last mentioned lake 81 yards above the level of the sea, from barometrical observations ; but if I have made an error by determining Kendal 5 yards too high, the results of our observations will be reconciled.* * The height of the following places above the level of the sea have been determined as under; the observations with the barometer were made by myself, and those with the theodolite by Mr. CrostHwalteE.
