BIOGEAPHICAL NOTICES OF EMINENT YORKSHIRE GEOLOGISTS. 
II. "ADAM SEDGWICK." BY T. M'KENNY HUGHES, M.A., 
WOODWARDIAN PROFESSOR OF GEOLOGY, CAMBRIDGE. 
The story of Adam Sedg-wick carries us back through years full of 
stirring events, to times very different from our own, whether we 
regard the changes of the political world or the march of scientific 
discovery. 
In a letter written when he was an old man, he says : — " On 
the 22nd of this month I shall have completed my 78th } ear, and 
78 such eventful years ! I well remember the breaking up of the

benefits of the political freedom of Western Europe), starting on a 
new road towards political strength and national greatness, and 
advancing on it at a speed unmatched in the past history of man. 
"And the triumph of sciences have gone hand in hand with 
these great world-wide movements ; or perhaps it would be nearer 
the truth to say, that science has been their main spring and living
