ADDRESS. 
GENTLEMEN, 
You have learnt this morning, from the annual report of the 
Council, that the financial affairs of the Society continue to flourish; 
and that since our last anniversary we have published the conclud- 
ing part of the third volume of our Transactions, and the first part 
of a fourth volume. Another part of the same volume is nearly 
ready, and the Council have directed their thoughts seriously to the 
means of preventing, in future, the accumulation of such heavy 
arrears of unpublished memoirs. The delays have hitherto arisen 
from a desire to print all papers containing original and valuable 
matter in the order in which they were presented; but many have 
been sent to us in so unfinished a state as to retard the printing of 
the rest, and, as the science advances rapidly, and new facts pour in 
daily, the authors even of the most finished memoirs soon require 
to make additions and corrections, and thus the evil is continually 
augmenting. ‘The Council have therefore resolved, for the future, 
to print at once those memoirs which are in the most complete 
state, without waiting for others which are imperfect. 
During the last year there have been elected into the Society 45 
new members, and we have lost 4 by resignations and 12 by deaths. 
Among the names of the deceased Fellows I may mention those of 
Mr. Goodhall and Mr. Mammatt as having zealously contributed to 
the progress of our science. Mr. Goodhall was an active collector 
of British fossils, and to his labours we owe many valuable contri- 
butions to our museum, and the discovery of shells of new species 
figured in Sowerby’s Mineral Conchology. The work of Mr. Mam- 
matt, on the Coal-field of Ashby-de-la-Zouch, has been honourably 
mentioned by my predecessor Mr. Greenough, in his last anniver- 
sary speech. Mr. Mammatt had superintended, for more than thirty 
years, the working of extensive coal mines, and kept a record of the 
details of various sections with which he was practically acquainted. 
To these documents he has added several plans of remarkable faults 
which intersect the carboniferous strata of Leicestershire. He has 
shown that on one side of one of these faults the beds rise to the 
height of 500 feet above the corresponding beds on the other side, 
yet the mass of uplifted strata does not project above the gene- 
ral level of the country. He infers, therefore, that it has been 
removed by denudation, and that the wreck of it alone now: 
remains on the surface in the shape of sand and boulders. Mr. 
Conybeare has drawn similar conclusions respecting analogous phz-= 
nomena observed on a still greater scale in the Newcastle coal di- 
strict.* Whether the denudation was sudden or gradual, or whether 
the faults were produced at once or were the result of a series of 
movements, are points which the limits of this discourse will not
