| Description | Daily meteorological readings at the Royal Society's apartments at Somerset House, London, England. Each printed sheet contains two sets of observations, from 9.00 a.m and 3.00 p.m. Both have basic readings of air pressure and temperature from an internal barometer with an attached thermometer, and an external thermometer, The morning readings also have highest and lowest points of a 'self-registering' [thermometer], with dew-point, rain and wind. Below these, general remarks on weather and cloud conditions.
The 'Meteorological Journal', kept by the Assistant Secretary, was published in the Philosophical Transactions each year, usually in parts during the year. The Assistant Secretary role, and overall responsibility for the meteorological observations, changed from Hudson to Roberton in April 1835. The design of the form changes slightly in this year, being smaller, and with additional categories of 'Remarks', from 'A.M and P.M.', to 'A.M., Noon, P.M., and Evening'. |
