Abstract
DR. HOLETSCHEK, of the Vienna Observatory, has recently communicated to the Imperial Academy of Sciences a paper on the magnitude and brilliancy of comets and their tails, with the view of arranging them in “magnitudes” or orders of brilliancy in a manner similar to that in which stars are arranged according to their lucidity. Further, from the data given as to the apparent length of the tail, the true length of the tail has been computed, and an inquiry instituted as to the possibility of tail formation and its probable length, based on the resulting magnitude of the comet and its perihelion distance.
