MADRAS MERIDIAN CIRCLE OBSERVATIONS, 1865, 1866, 1867.—We have recently received from the Director of the Madras Observatory, the “Results of the Observations of the Fixed Stars made with the Meridian Circle at the Government Observatory, Madras, in the Years 1865, 1866, and 1867,” and are glad to see by its appearance that Mr. Pogson is continuing his efforts to remedy the most deplorable delay which has attended the publication of the observations made under his care. The present volume is in continuation of the one which appeared a year and a half ago, and which contained the results for the years 1862–64. The instrument employed and the class of objects observed were the same as in the three earlier years; the objects selected being the moon and moon culminators, Mars and companion-stars, minor planets, the brighter stars down to the fifth magnitude, and as many unnamed stars as possible below 120° N.P.D., and not fainter than the eighth magnitude. The present and preceding volumes have been confined to stellar observations, and these are given separately for each year in the twofold form of star-ledger and annual catalogue. The Star Catalogue will follow at the conclusion of the publication of the results for the separate years, and it is hoped that it may be succeeded by a volume of planetary and cometary results. Very little interest or value now attaches to these sadly overdue volumes of annual results, except as an indication that the evil of delayed publication is now really recognized, and as affording a hope that the one really useful work, the General Star Catalogue, may soon appear. It is but due to Mr. Pogson, however, to remember that his position is one which has presented many difficulties, seeing that he had, as he states in the present volume, “no European assistance, and too inadequate a staff of natives even to admit of duplicate calculations.”
