[16] Dolland's instrument, called an "atmospheric recorder," is described in the Official, Descriptive and Illustrated Catalogue to the Great Exhibition, 1851, London, 1851, pt. 2, pp. 414-415. As the George Dolland who joined the famous Dolland firm in 1804 would have been about 80 years of age in 1850, the George Dolland who exhibited this instrument may have been a younger relative.
[17] The Osler anemometer and most of the other self-registering instruments mentioned in this paper are described and illustrated in C. Abbe, "Treatise on Meteorological Apparatus and Methods," Annual Report of the Chief Signal Officer for 1887, Washington, 1888. The use of the Osler instrument at the British Association's observatory at Plymouth is mentioned in the Association's annual reports from 1838. There were a number of earlier self-registering anemometers, but no evidence of their extended use. See J. K. Laughton, "Historical Sketch of Anemometry and Anemometers," Quarterly Journal of the Royal Meteorological Society, 1882, vol. 8, pp. 161-188.
