REPORT. 
In presenting their Report for the past year, the Council have, 
in the first place, to call the attention of the Academy to the pro- 
gress which has been made in publishing their Transactions since 
the 16th of March last. 
The First Part of the Twenty-Third Volume has been published, 
containing Mr. Donovan’s paper on ‘‘ Galvanometric Deflexion,” 
Mr. Haughton’s paper on “‘ The Solar and Lunar Diurnal Tides on 
the Irish Coast,” and Mr. Mallet’s paper on ‘‘ The Physical Condi- 
tions involved in the Construction of Artillery.” 
It will be remembered that the observations upon which Mr. 
Haughton’s highly valuable paper is based were undertaken by 
the Academy in the year 1850. The Council have to congratulate 
the Academy on the valuable result which Mr. Haughton’s zeal and 
ability have deduced from the task which they undertook,—a result 
which they hope will soon be completed by the discussion of the 
question of Semi-Diurnal Tides. 
Another Science Part of the Twenty-Third Volume of the 
Transactions is in progress. 
Mr. Salmon’s paper on “ Reciprocal Surfaces” has been printed 
off. Mr. Renny’s paper on ‘‘ The Hygrometric Correction of Baro- 
metrical Measurement,” and Professor Downing’s paper on “ The 
Draining of the Haarlem Lake,”’ are both in type; and Mr. For- 
ster’s paper on ‘‘ The Molecular Formation of Crystals’’ is in the 
compositor’s hands. 
Towards a Polite Literature Part of the same Volume, the fol- 
lowing progress has been made:—
