Side 312 - The Earl of Chatham, with his sword drawn Stood waiting for Sir Richard Strachan ; Sir Richard, longing to be at 'em, Stood waiting for the Earl of Chatham.
Side 224 - This remarkable law of variation certainly appears strongly to suggest the revolution round it of some opaque body, which, when interposed between us and Algol, cuts off a large portion of its light ; and this is accordingly the view taken of the matter by Goodricke, to whom we owe the discovery of this remarkable fact...
Side 262 - ... funds have been provided in the estimates. The work has been intrusted to Mr. Grubb, with whom I have arranged the details of the tube, which is to be of special construction, adapted to the conditions of the mounting, and available for spectroscopy and photography as well as for eye observations. Mr. Grubb proposes to provide means for readily separating the lenses of the object-glass to such a distance as will give the proper correction for photographic rays.
Side 67 - Je mis tous mes soins à déterminer exclusivement la position du radiant, ce qui ne présentait aucune difficulté. Voilà de quelle manière je m'y pris. Je fixai attentivement sa position approximative et ensuite je traçai sur le papier le chemin de quelques-uns de ces météores qui se détachaient autour de ce point.
Side 202 - Anwers thinks that it would be premature to attempt any correction of the catalogue-places before the completion of the general revision, which has been undertaken by the observers of the zones and by the Pulkowa astronomers. He, however, takes this opportunity of publishing the results of investigations he has made as to the mean errors of the different catalogues employed in the formation of the Fundamental Catalogue, viz, Pulkowa, 1845 and...
Side 109 - Washington (the difference of latitude being 11' 7"), but we believe no observations have actually been made yet. Effect on the earth's motion produced by small bodies passing near it. — Professor Newton points outt that the space through which the earth travels is traversed also by small bodies, or meteoroids. The impact of these bodies upon the earth, and the consequent increase of the earth's mass, have their effect upon the earth's motions, both of rotation and * Amer.
Side 196 - Durchmusterung, that upon the meteoric theory of the zodiacal light it is to be expected that a continuous zodiacal band should be present; but the question of its actual visibility is complicated by the slight maxima of stellar density which are situated along those parts of the ecliptic most readily accessible to observation from stations in the northern hemisphere.
Side 84 - We add also that, up to the present time, we have not been able to see the nebula in our telescopes.
Side 172 - No. 2715) that the great similarity of the outburst in Andromeda in 1885 to the phenomenon observed by him in 1860 in the cluster 80 Messier in Scorpio is a strong confirmation of Professor Seeliger's views. The probability that two variable stars of such exceptional character should be projected, in one case on a close star-cluster, in the other case on an object which appears to be, in part at least, a close star-cluster, is so small that it is almost necessary to refer these outbursts to physical...
Side 175 - That the Conference expresses the hope that, as soon as may be practicable, the astronomical and nautical days will be arranged everywhere to begin at mean midnight.
