Page 339 - Bullettino di Bibliografia e di Storia delle Scienze Matematiche e Fisiche Tomo XXIII, Maggio 1885. Roma. Total 28. . ' • Mr. RE Kingsford, MA, read a paper on "The Campaign of 1815.
Page 150 - I. All self-luminous bodies in the celestial spaces are composed of meteorites, or masses of meteoritic vapour produced by heat brought about by condensation of meteor-swarms due to gravity. II. The spectra of all bodies depend upon the heat of the meteorites, produced by collisions, and the average space between the meteorites in the swarm, or in the case of consolidated swarms upon the time which has elapsed since complete vaporization.
Page 106 - ... it is generally admitted that all the evidence that has been acquired, on lines of inquiry until recently followed, has failed to solve the problem. During the last few years, however, the discussion has assumed a somewhat different aspect. The question still is, whether free nitrogen is an important source of the nitrogen of vegetation generally, but especially of the...
Page 131 - Only seven lines in all have been recorded up to the present in the spectra of nebula;, three of which coincide with lines in the spectrum of hydrogen and three correspond to lines in magnesium. The magnesium lines represented are the ultra-violet low-temperature line at 373, the line at 470, and the remnant of the magnesium fluting at 500, the brightest part of the spectrum at the temperature of the bunsen burner.

Page 153 - ... of the whole mass. XV. Beginning with meteorites of average composition, the extreme forms, iron and stony, would in time be produced as a result of collisions. XVI. In recorded time there has been no such thing as a world on fire...
Page 153 - XVII. Special solar applications. a. The solar spectrum can be very fairly reproduced (in some parts of the spectrum almost line for line) by taking a composite photograph of the arc spectrum of several stony meteorites, chosen at random, between iron meteoric poles.
Page 334 - The deviation of the rays thus indicated was in the same direction and of the same order of magnitude as that for cathode rays produced in a vacuum tube.
Page x - ... command of the Fanny, and there displayed a gallantry which earned his early promotion to the rank of commander. After this Commander Key served for three years in the Bulldog on the coasts of Italy and Sicily, and was made a captain in 1850. He served in command of the Amphion in the Baltic, taking part in the capture of the forts of Bomarsund and other operations. At the end of the war, when the honours were distributed, he was nominated a CB In the following year, 1856, he married Charlotte...
Page 148 - It seems to me that we have a series of indications of what (for want of a better phrase) may be called the period of life of a star or group ; beginning with the glowing gases developed by impacts of agglomerating cold masses. (Planetary nebule and others irresolvable, such as those of Orion, Lyra, &o., where the spectrum consists of a very few bright lines only.) " (Professor Tait,
