COUNCIL FOR 1869 . 
11 
The great Telescope, on the construction of which Mr. Cooke 
had been engaged for some years previous to his death, may 
justly he considered as marking an epoch in the history of 
Astronomy, and the Curators have much pleasime in informing 
the Members that this instrument, through the labours of Mr. 
Cooke’s sons and successors, has now been completed. When 
the work to be achieved by it shall be made known, the Society 
cannot regard as a slight honour the fact that the largest 
refracting Telescope ever constructed was designed and manu¬ 
factured by Members of this Society. 
The Curator of Meteorology reports:—The mean tem¬ 
perature of York for the year 1869 was 48°, nearly the exact 
mean of thirty years. February, April, and June wnre each 
several degrees above a mean temperature. March and May 
were much below. The range of temperature in the year was 
60°. The rain-fall of the year is four inches above a mean. 
This excess belongs to the first five months of the year.
