less destructive than the great earthquakes of South America. 

 One effect was to bury under sand some of the most important 

 oyster beds in that part of the world. 



From the 1st to the 11th violent shocks of earthquake were 

 felt at Manilla. 



Greenwich. — The warm period which set in on September 

 4th continued until the 16th of October ; the average excess of 

 mean daily temperature for the whole period of forty-three days 

 was 3-4°, and of the first sixteen days of October 3-7°. On the 

 17th of October the weather suddenly changed and became cold 

 and wintry in its character, with sleet, hail, frost, and snow, and 

 strong winds. This severe cold weather continued with but 

 slight variation to the end of the month. The pressure of the 

 wind on October the 16th and 19th reached thirty pounds to 

 the square foot. 



The mean temperature of October was 48'9°, being 0*8° lower 

 than the average of 98 years, higher than the corresponding 

 period in 1868 and 1867 by 1° and 0-2° respectively, but lower 

 than in any year in the period 1853-66. The rainfall was I'l 

 inches below the average. 



The readings of the barometer were generally high. From 

 the 4th to the 14th they were remarkably steady, scarcely vary- 

 ing ^th of an inch throughout the period, and constantly above 

 the average. On the 14th a decrease set in and lasted till the 

 16th. The minimum at that time, at the height of 160 feet 

 above the mean level of the sea, was 29*13 inches. From the 

 20th to the end of the month the readings were, with but two 

 exceptions, above the average. 



A very remarkable halo and mock moon were seen in North- 

 umberland, and many other parts of the country, on the 17th. 



North Sunderland. — The first half of the month was charac- 

 terised by mild dull weather : the latter part by high gales of 

 wind with rain. On the 26th, 27th, and 28th, there was a 

 terrific storm of wind from N., and very cold. 



Wallington. — The weather from the 1st to the 15th was dry
