COUNCIL FOR 1866. 
11 
regard to rain-fall, the year was as anomalous as in temperature, 
the amount, 25*71 inches being 2 inches above a mean. There 
was an excess in June and July, a little below a mean in August, 
and a large excess in September. The rainfall in these months 
was unfavourable to the northern harvests. The mean height of 
the Mercurial column was low, according with the result in the 
Registry of Rain-fall. The least amount this year occurred in 
May, 0*58 inches, the greatest in September, 4*04 inches. 
In consequence of the permission granted to the Curator, 
by a Minute of the Council, to employ Mr. Silvanus Thompson, 
junr., to keep the Registers in the Curator’s absence, he has been 
enabled to supply a traced diagram of the maximum and 
minimum temperatures of the months from July to December 
inclusive. These diagrams have been posted in the vestibule of 
the Museum. The table number 2, supplying the Registry of 
the Rain-fall for Malton, Ackworth, Settle, &c., accords in its 
statement of increased amounts with that of York. This is 
particularly noticeable in the return for Settle. Mr. John 
Tatham states that the Rain-fall there (56T7 in.) is the largest 
amount he has registered in the course of years, except in 1848 
when the amount was 57*49.
