Address to the Geological Society ^ delivered at the Anniversary^ on 

 the \7th of February, 1837, by Charles Lyell^ Jun.^ Esq., 

 President. 



Gentlemen, 



You will have learnt from the Treasurer's Report that the finances 

 of the Society are flourishing, and they would have appeared in a 

 stilt more prosperous condition, had we not expended above 500^. 

 within the year on onr Transactio^ns. Part of this sum has already 

 been repaid by the sale of the volume just published, of which I 

 may safely say that it yields to no preceding number in the value 

 of Its contents or the extent and beauty of its illustrations. 



The total number of Fellows of the Society, exclusive of Ho- 

 norary and Foreign Members, at the close of the year 1835, was 

 <;70 ; at the close of 1836, 709 ; being an actual increase, after de- 

 ducting 14 for deaths, removals, and resignations, of S9 Fellows*. 



We iKive to lament the loss of Dr. Henry, of Manchester, so 

 highly distinguished as a chemist and philosopher, and who took a 

 warm interest in the progress of our science. Our list of Foreiga 

 Members has been diminished by two deaths, those of Professor 

 Hoffmann of Berlin, and Baron Ferussac of Paris. 



Professor Frederick Hoffmann was suddenly cut off in his 39th 

 year, at the moment when the scientific world were impatiently 

 expecting his account of the Geology of Sicily. You are probably 

 best acquainted with him as the author of the great Geological Map 

 of Western Germany, in which he made known the results of many 

 years of patient and accurate research. This Map, published in 1829*, 

 was divided into twenty-four sheets, and was followed in 1830 by an 

 Atlas containing sections, and a more general map on a smaller scale 

 of the same country. In the same year the autlior*s Geography and 

 Geology of North-western Germany appearedf, which may be re- 

 garded as a commentary on the great map, comprising a descrip- 

 tion of the p!iysical outline of the country, its mountains, valleys, 

 plains, and river-courses, and a sketch of a portion of its geo- 



• The return of the number of Fellows, and the deaths alluded to in this 

 Address, refers exclusively to the year 183(3, and not to the period inter- 

 vening between the last and present Anniversary.
