Abstract
MY attention was called to a letter on this subject in your issue of the 29th ult. (vol. xxiv. p. 510), though not in time to enable me to answer it last week. I take this opportunity of stating that the gentleman to whom the idea of the instrument was originally due, and who has defrayed the whole cost of its construction, is the Rev. J. M. Wilson, M.A., head-master of Clifton College (not Dr. Wilson, as mis-stated in the Association Journal at York and in your abstract). The objection that the air does not move “parallel to itself,” by which I presume is meant in planes parallel to its general direction, does not apply to this any more than to any other cup anemometer. Only the horizontal component of the wind's velocity is sought, and this is given with tolerable accuracy. I have no means of knowing to what extent Mr. Burton's integrator resembles the anemometer in question, but it should be noticed that the two instruments are of a different kind and for a different purpose. Mr. R. Scott was in the chair when the paper was read at York, and joined in the discussion. Prof. Stokes was also present, and has since been in correspondence with me on the matter. Neither of these gentlemen, however, mentioned any other instrument as at all resembling it; indeed upon its being compared to that of Dr.von Oetlinger, Mr. Scott took occasion to point out at least one important difference, viz. the cost.
