below the fall for 1864, which was also comparatively a dry 
vear. Although the first three months had about an average 
fall, the second three 'months had a fall greatly below the 
average. The same remark applies to the third and fourth 
quarters of the year. The fall of rain was remarkably small 
in June, September, and December; and it will also be seen 
that with the exception of the four months of January, May, 
August, and October, every month had a rainfall below the 
average. As compared with any other month, the rainfall in 
October was excessive. The number of days upon which 
rain fell was also greatly below that of many previous years. 
Mr. Baxendkll, F.R.A.S., read the following “Note on 
the Variable Star T Aquilse.” 
In the communication made to this Section on the 12th of 
November, 1863 ( Proceedings . vol, iii. p. 195), announcing 
the discovery, at Mr. Worthington’s observatory, of the vari- 
ability of T Aquilse, I gave the times of one minimum and 
one maximum, but was unable to give a trustworthy value of 
the length of the mean period. The observations which 1 
have since made have however enabled me to determine with 
tolerable exactness the times of three more maxima and two 
minima, thus affording the means of ascertaining the value 
of the mean period within very moderate limits of error. 
The observed times of maximum and minimum and the 
corresponding magnitudes are : —
