One of the medals struck on the occasion of the coronation 

 of the present King and Queen of Sweden, presented to the 

 Society by the University of Christiana, excited much admi- 

 ration on account of the excellence of medallurgy it dis- 

 played. 



A Paper " On the Kaloscope," by Mr. W. H. Heys, was 

 read by Mr. George Mosley This Paper was communi- 

 cated by the Microscopical Section, and an abstract will be 

 found in the Proceedings, No. 8, under that head. 



PHYSICAL AND MATHEMATICAL SECTION. 



January 31st, 1861. 



Mr. Mosley read from the Gibraltar Chronicle of the 8th 

 instant, an abstract of meteorological observations taken at 

 the Royal Engineers' Observatory, Gibraltar, during the year 

 1860. From the results given it appeared that while the 

 weather in Enjrland during^ the last Summer and Autumn 

 had been unseasonably cold and wet, at Gibraltar, on the 

 contrary, it had been remarkably warm and dry. During the 

 six months from the 30th of April to the 1st November, the 

 fall of rain at Gibraltar had been only 1-237 inches, whilst at 

 Manchester, according to Mr. Vernon's returns, it had been 

 21-858 inches. It was also remarkable that the maximum 

 degree of humidity of the air at Gibraltar, as determined in 

 the usual way by the wet and dry bulb thermometers, oc- 

 curred on the 30th of September during the long period 

 of drought. The average fall of rain at Gibraltar, from 

 eight years' observations, is 41-2 inches, but during I860 the 

 amount collected in a gauge on the ground was only 34-874 

 inches, and in a gauge 25 feet above the ground 32-358 inches.
