206 Miscellaneous Intelligence. 



The shock of an earthquake was felt on the morning of the 

 20th of December, about 7h. 55', at Mittenwald, in Bavaria. 

 It lasted seven or eight seconds, and passed from south to 

 north. The wind from the south was very still. 



At the time of the earthquake which so dreadfully devastated 

 the territory of Kutch in India, shocks were felt at other places 

 considerably removed from that neighbourhood. An earth- 

 quake happened at Chunar andMirzapore on the same day, (June 

 16,) about eight in the evening, and at Chunar the motion is de- 

 scribed as being accompanied by a noise in the air like the rapid 

 flight of birds. A slight agitation of the earth took place also 

 at the same time at Calcutta. At Jionpoor the shock was 

 strong, and there were three distinct vibrations from west to 

 east. It occurred about half past eight o'clock, lasted nearly 

 25 seconds, and was not accompanied by any rumbhng noise. 

 At Sultanpoor, Oude, the shock is described as being very 

 severe and awful. The weather was very hot at both these 

 latter places, and no rain had fallen. 



A strong earthquake occurred at Port Glasgow, about half 

 past eight o'clock in the morning of 22d January, lliere were 

 three distinct shocks, and the rumbling noise which preceded 

 them seemed to come from the north, as well as the heaving of 

 the earth. A rapid thaw had commenced that morning, succeed- 

 ing a long and sharp frost. At the same time the waters in 

 Loch Lomond were agitated and rose somewhat, and some 

 persons who were crossing it were alarmed by the sudden 

 rippling of the water. The earthquake was felt also at Condrie, 

 Perthshire, Keppin, Dumbarton, ^c, at the same time. 



10. Insulation of Electricity . — M. Haiiy in his method of dis- 

 tinguishing precious stones, ^c, has called in the aid of elec- 

 tricity ; joining the electric indications given by a gem when 

 rubbed or pressed to its other physical characters. That these 

 indications may be obtained more readily, M. Haiiy has invented 

 two small instruments, very portable and ready, to furnish the
