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 England 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 
2 1 ’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 1860 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.
