(329 - 343) pages; extracted from the Royal Society Transactions. James Farquharson (1781 - 1843) British writer on science, among his several scientific interests here "...explained the formation of ice at the bottom of running water, a phenomenon already discussed by Arago and others, in terms of the radiation of heat from the bottom of the stream cooling its bed more quickly, under certain conditions, than the water flowing over it. He also sent the Royal Society copies of the registers of temperature that he kept for a long period of years. This led him to investigate the origin and progress of currents of colder and warmer air moving over the face of a flat country surrounded by hills, and their effects upon vegetation...."
