This series might lead to the conclusion that the annual 

 amount of rain was decreasing in the plain of York, were it 

 not for the compensations to be looked for in a longer series. 

 The range in the amount of rain falling at York is very exten- 

 sive, varying from 36 inches in 1848 to 18 inches in 1850. 



The annexed table exhibits a condition in regard to the 

 prevalent winds, quite coincident with the diminished tempera- 

 ture of the year. In 1854, there were 154 days of W. and 

 S. W. winds against only 102 in 1855. 



The Gentiana verna flowered on the 18th of May against 

 the 18th of April, 1854. 



Two thunder storms were noticed in June ; four in July ; 

 and one on the 7th and one on the 8th August, a period, as we 

 have formerly observed, of the almost regular occurrence of 

 electrical display. 



The instruments in the Observatory have been kept in order 

 by Mr. T. Cooke. Transits have been observed and true time 

 registered.
