Page 144 - Of the seven stars whose spectra are here announced as of Type IV., the first, second and seventh are normal. The spectra of the others contain rays of much shorter wave-length than ordinary fourth type stars.
Page 145 - Curiously enough, in the margin of the principal MS. there is a note In Greek by some unknown writer, who says that he ' once saw one of these creatures which had been sent to our King by the Ruler in Alexandria, and the barbarian who brought the animal called it fopd</>is.

Page 145 - Stars having spectra of the fourth type are commonly regarded as red stars ;" which indicates that the Harvard observers considered that, in general, stars of Class R are not red.
Page 132 - Estimates from these plates gave the approximate limiting magnitudes, 8.2 to 9.2. This object was found to be variable by Mrs. Fleming on November 26, 1904, but since the change was slight, about half a magnitude, on the plates examined, publication was withheld until the star was rediscovered independently by Miss Leavitt in her examination of the Harvard Maps of the Sky. She found a change of about 0.7 magn.
