the weather, which will be of great ufe to those who have not been accuftomed to make fuch obfervations, and will fave much labour to those who have. It contains ruled columns for a register of the barometer, thermometer, hygrometer, and wind, at three periods in every day, and the quantity of rain falling each day, with columns for particular and general obfervations. Perhaps one ftill more convenient might be drawn up, and printed at the expence of the fociety. The fubject of Meteorology is treated in a very philofophical and fatisfactory manner by Dr. Darwin, in the firft volume of his Botanic Garden. The theory of the winds there given, bids fair to explain moft of the meteorological phenomena. And, I am of opinion, that if regifters could be kept fo as to determine at what hour the winds began to change in many parts of the world, fomething concerning the weather might be learnt: for, (as Dr. Darwin obferves, in a letter which I lately received from him) the variation of the courfe of the wind feems to be the cause of, or key to, the other phenomena of froft or rain; and this, which is the principal circumftance in atmofpheric theory, is most deficient in experiments. For the convenience of comparing the different parts of the following obfervations, I have divided |
