Minutes of the last meeting were read
' Resolved;
1. That it is expedient to introduce improvement in the present mode of making and registering the Meteorological observations of the Society.
2. That, for this purpose instruments of the most approved construction be provided which may also serve as standards to those who may wish to consult them; for which every facility should be offered.
3. That a strict comparison be instituted between the standards and the instruments now in use and the necessary corrections of the latter noticed in the Register.
4. That it is expedient to provide a convenient place for making the observations which shall be as much as possible free from the great objections to the present situation of the instruments.
5. That no exertions be spared to commence the regular observations and the new register on the 1st January 1831 and that the times of observing be the same periods of the day as those of the Royal Observatory at Paris viz 9 am, noon, 3 pm, 9 pm
6. That directions be given to Mr Harmon to select some proper tube of equal cylindrical bore throughout its length, for making under the immeditate inspection of the Committee, a thermometer upon which the melting point of ice, the boiling point of water and the melting point of fine tin may be exponentially fixed and set off upon a scale of equal parts of which 180 are to be comprised between the freezing and boiling points of water ....
7. That Mr Crichton of Glasgow and Mr Troughton of London be requested to make each a similar thermometer for comparison; and that they be directed to take the three points when the whole stem of the instrument is exposeed to the respective temperatures and to mark at the mean pressure of 30lbs - account to be given of the method used and the specific gravity of the mercury compared to water at 40.
8. That Mr Newman be directed to prepare a Barometer mounted like Dr Prout's with two tubes of not less than half an inch bore guarded at their lower extremities with broad rings of Platinum and that the same be boiled under the inspection of the Committee.
9. That it is desirable to obtain a standard thermometer and Barometer from the best instrument makers of France and Germany and that Captain Sabine be requested to take the proper steps for carrying this resolution into effect.
10. That a water Barometer be erected in the Hall of the Society according to Mr Daniell's suggestion. ' |
