XXI.—Additional Observations on the Polarisation of the Atmosphere, made at St Andrews in 1841, 1842, 1843, 1844, and 1845

Published online by Cambridge University Press:  17 January 2013

Extract

Since the publication of my “Observations on the Polarisation of the Atmosphere,” a long and elaborate Memoir on the same subject, by Dr R. Rubenson, has appeared in the Acts of the Royal Society of Sciences of Upsal. The observations which it contains were made with the finest instruments, and with a degree of accuracy which had not been attempted by previous observers. They were begun at Upsal in 1859, and carried on at Rome between the 6th of June and the 5th of August 1861, at Segni in the Campagna, between the 6th and the 27th of August 1861, and at Rome from the 5th of October 1861 to the 27th of July 1862.
