VIII. Reduction of anemograms taken at Armagh Observatory in the years 1857 to 1863

The instrument with which these observations were made is described in the Transactions of the Royal Irish Academy, vol. xxii., and a continuous series of its records exist from 1845 to 1870. With the limited resources of this Observatory it was not in my power to reduce them; but it seemed to some distinguished members of the Royal Society desirable to ascertain whether such observations are competent to develop any laws amid the seeming lawlessness of the winds, and they obtained for me a grant from the Government Fund to discuss the anemograms of these seven years. Unfortunately the work has been long delayed by various accidents.
