Excerpt from Observations of the Aurora Borealis: From September 1834 to September 1839 Ashurst, September 30, 1836.-at about 9b the Aurora appeared as a very brilliant and distinct white arch about 8° high, from the more westerly-por tion of which a fine deep garnet-coloured blush spread itself over a great portion of the sky, although the moon was shining brilliantly. This was succeeded by irregular undulating flashes, resembling in character the remarkable display of November 18, 1835, but much less brilliantly developed. Soon after 10h all trace of the Aurora was lost. The next morning was ushered in with violent wind and rain. The word flash is perhaps too expressive of rapidity of motion to be applied to the Aurora. A lambent undulating glow, like that of phosphorus, is an expression more truly descriptive of the phenomenon. Ashurst, October 15, 1836. - Much Auroral light generally diffused throughout the sky. At midnight a few very faint streamers were perceptible. Sky calm and cloudless. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Aurora Borealis The first work, devoted entirely to the study of Polar Auroras, was written in France; it is entitled 'Traite Physique et Historique de l'Aurore Boreale, ' and was published in 1733 by De Mairan, in the 'Memoires' of the 'Academie des Sciences.' We must allow a century to elapse before we find anything to be compared with it in importance and volume, when the work 'Aurores Boreales' appeared in the collection of the corvette 'Recherche.' This volume, accompanied by magnificent plates - of which we shall reproduce the most interesting - contains records of observations of the aurora borealis taken in Lapland during the winter of 1838-39 by Bravais, Lottin, Lillihoeoek, and Siljestroem. Bravais added general remarks on this phenomenon, and discussed the principal observations collected at that date, and the various hypotheses put forward to account for them.
