Page 140 - Kosse's reflector, or the exquisite defining power of the great achromatic at Cambridge, US, is evidently perceived to consist of clustering stars. There can therefore be little doubt as to the whole consisting of stars, too minute to be discerned individually even with these powerful aids, but which become visible as points of light when closely adjacent in the more crowded parts in the mode already more than once suggested.
Page 205 - Untersuchung über die Bahn des Planeten Themis, nebst einer neuen Bestimmung der Anziehung des Jupiter.
Page 141 - These luminous points, in some nebulae at least, must be regarded as themselves gaseous bodies, denser portions, probably, of the great nebulous mass, since they exhibit a constitution which is identical with the fainter and outlying parts which have not been resolved. These nebulre are shown by the prism to be enormous gaseous systems...
Page 198 - Über das Problem der drei Körper im Allgemeinen, und insbesondere in seiner Anwendung auf die Theorie des Mondes.

Wenn eine Wolke dort sich gebildet hat, so werden alle über derselben liegenden...
Page 236 - Determination Telegraphique de la Difference de Longitude entre les Observatoires de Geneve et de Neuchatel.

L'effort qui résulte des attractions du Soleil et de la Lune sur les eaux de la mer et le retard ou l'avance de la marée sur l'heure du passage de la Lune au méridien varient suivant que les deux astres s'écartent ou se rapprochent...
Page 135 - On the Influence of the Seasons upon the Rate of Decrease of the Temperature of the Atmosphere with Increase of Height, in different Latitudes in Europe and Asia.
Page 142 - Since the spectrum of the light of the coma is unlike that which characterizes the light emitted by the nucleus, it is evident that the nucleus is not the source of the light by which the coma is rendered visible to us. It does not seem probable that matter in the state of extreme tenuity and diffusion in...
