Page 422 - Bearing in mind the history of this star from the time of its discovery by Schmidt, it would seem certain that we have an instance before us in which a star has changed into a planetary nebula of small angular diameter. At least it may be safely affirmed that no astronomer discovering the object in its present state would, after viewing it through a prism, hesitate to pronounce as to its present nebulous character.
Page 119 - Indian rainfall and solar activity,1 attention has more recently been devoted to an examination of the variations of pressure over the Indian and other areas. 1. It is well known that in India during the summer months (April to September) and during the winter months (October to March) low and high pressures respectively prevail. In the case of the latter, the pressure is found to exhibit very remarkable and definite variations, and is in excess every...
Page 193 - ... according to the law of the inverse square of the distance. The same century in which the
Page 122 - ... and 35-year periods apparently influence the short-period variations; but even this does not explain some anomalies already met with, and should the solar origin of these short-period pressure changes be subsequently confirmed, some of them not constant in all localities will have to be explained; and it is possible we may obtain in this way some new knowledge on the atmospheric circulation.
Page 121 - A preliminary reduction of the Italian observations of prominences observed on the sun's limb since 1871 was first undertaken. The result of this inquiry indicates that, in addition to the main epochs of maximum and minimum of prominences, which coincide in time with those of maximum and minimum of the total spotted area, there are prominent subsidiary maxima and minima having a similar short period and also coinciding in time.
Page 244 - Aberdeen in 1876, and in the same year he became a Fellow of the Royal Society.
Page 181 - ... Major Burrard's investigation to show that the latent causes of disturbances must be sought over very extended areas. This work of latitude determination has now been completed under the superintendence of Captain L. Conyngham, and Kalianpur has been surrounded by a chain of stations, of which four are situated at an average distance of nine miles and four at an average distance of thirty-five, and the unexpected result of the discussion is to show that local attraction causes a northerly deflection...
Page 57 - ... chiefly towards more effectually securing that Grants made should be expended for the purpose for which they were given, and that objects of permanent interest obtained by Grants should be properly disposed of. The only two Grants made this year which call for special mention...
Page 122 - The close correspondence between the epochs of these subsidiary pressure variations and those representing prominence frequency, suggests not only their very close relationship, but that the terrestrial pressure quickly answers to the solar changes, while, so far as the work has gone, it would appear that rainfall and snowfall are subsequent effects.
