On the instruments used at Mannheim see Gerland and Traumüller, op. cit. footnote 1, p. 349ff. The Princeton physicist Arnold Guyot prepared a set of instructions for observers that was published in Tenth Annual Report ... of the Smithsonian Institution, 1856, p. 215ff. It appears from the Annual Report of the British Association for the Advance of Science in the 1830's that the instruments used in England were nearly the same as those later adopted by the Smithsonian, although British observatories were beginning to experiment with the self-registering anemometer at that time. A typical set of the Smithsonian instruments is shown in figure 1.
