In August, 1879, at the request of the Meteorological Council, I undertook an experimental comparison of the various methods of determining the hygrometric state of the air, with the following instruction, “The chemical method to be employed, and with it to be compared the dry-and-wet-bulb hygrometer, Regnault’s, Dines’s, Alluard’s, and the hair hygrometer.” Since that time I have devoted to the subject the time that was at my disposal, and I now beg leave to lay before the Council a statement of the experiments I have made and the results I have arrived at with respect to the chemical method and the dew-point instruments
