    56S considerably greater at Gravesend, and greater still at Knights- bridge. In this respect too Penzance, retains its superiority even over Devonshire. Lisbon seems to have a less variable tem- perature than any part of Great Britain; and in Madeira, to judge by the monthly variation only, the advantage in this re- spect appears to be still greater. The greatest possible equability of temperature seems how- ever to be obtained in a sea voyage to a warm climate, in which the variation seldom amounts to half as much as in the most favourable situation on shore, even on a small island; and in pul- monary cases, the motion of a ship would probably, in general, be rather beneficial than otherwise, while the fatigue of travelling in bad roads, and the danger of sleeping in damp beds present an alternative, by no means favourable to a journey by land. The direction of the wind alone can seldom have any imme- diate effect on the salubrity of tlie climate, except by variously modifying its temperature, according to the seas or countries over which it blows. There is a method of computing the mean direction of the wind, which does not appear to have been hitherto adopted, but which affords a very simple and intelli- gible result, although somewhat laborious, if extensively ap- plied. It consists in finding the bearing and distance of a point, to which a light body would be carried by the wind in the course of the year, supposing the velocity to be constant, when its va- riations have not been ascertained by observation. It is ob- vious that the bearing of such a point will show at once the mean direction of the prevalent winds; and its distance, compared with the effect of a constant wind for the same time, as a unit, will indicate the degree in which those winds have prevailed.
