Les Observations méridiennes: Théorie et Pratique

Abstract

THESE two volumes comprise one of two completed sections out of a total of twenty-nine devoted to astronomy and celestial physics in a new form of scientific encyclopædia in which astronomy is only one of forty divisions. The whole work, if and when completed, should run to at least a thousand handy little volumes at a uniform price of 5 francs per volume. An index to the complete series is also promised, but it is hardly contemplated that the demand for the whole set will be very great, the idea being that each subject is to be totally distinct, so that a minimum of irrelevant matter need be purchased by any interested specialist, and that such sections as are rapidly rendered out-of-date may be quickly replaced by revised editions without necessitating alteration of the whole work. Les Observations méridiennes: Théorie et Pratique. By F. Boquet. Tome Premier, Instruments et Méthodes d'Observation. Pp. xi + 314. Tome Second, Corrections instrumentales et Equations Personelles. Pp. iv + 342 + xii. (Paris: Octave Doin et Fils, 1909.) Price, 2 vols., 10 francs.
