: Dr. MACVICAR, in a paper in the Ceylon Miscellany, July, 1843, recorded the results of some experiments, made near Colombo, as to the daily variation of temperature and Its effects on cultivation, from which it appeared that a register thermometer, exposed on a tuft of grass in the cinnamon garden in a clear night and under the open sky, on the 2nd of January, 1841, showed in the morning that it had been so low as 52°, and when laid on the ground in the place in the sunshine on the following day, it rose to upwards of 140° Fahr.
