The author explains about forty—four well-known prognostics belonging to the following groups —(l) diurnal; (2) sun, moon, and stars; (3) sky; (4) rain, snow, and hail; and (5) wells, springs, and coal-mine;,—by referring them to the isobaric conditions in which they are observed. By this means he is able to indicate ihe circumstances under which any prognostic fail?, as well as those under which it succeeds.— Preliminary inquiry into the causes of the variations in the reading of black-bulb thermometers in vacuo, by G. M. Whipple, B.Hc. It has long been known that there is a want of accordance between the different instruments used for measuring the intensity cf radiation, and with a view of ascertaining the cause of the variations in the readings of the black-bulb thermometers in vacua, the author has made a comparison with a number of these thermometers, the results of which are given in the paper. It is shown distinctly that the effect of an increased coating of lampblack on the bulb is to raise— the temperature, and also that the size of the thermometer-bulb is a most important factor in the case of this instrument-Report on the phenological observations for 1883, by the Rev.
