Address by Professor Kowarp Hurt, WA., PBS., E.GAS., President of the 
Section. 
Foiiowine the example of several Presidents of the Geological Section of the 
British Association, I purpose commencing our sprocersings by an address, selecting 
for my subject the volcanic phenomena of the district in which we are assembled. 
But before entering upon this subject, I am sure it will be equally in accordance 
with your feelings and my own if I give expression to the general and deep regret 
which is felt at the death (so little expected) of the late President of this Bachan 
Professor John Phillips, of Oxford, on the 24th of April last, in the 74th year of 
his age. 
The late Professor Phillips—As the nephew and pupil of Mr. William Smith, 
“the*Father of English Geology,” Professor Phillips was nurtured in an atmo- 
sphere of geological science which accorded well with his own tastes; and in his 
youth was the companion and assistant of his uncle in many a surveying-tour in 
the east and north of England. His subsequent appointment as Keeper of the 
Museum at York, and one of the Secretaries of the vordie Philosophical Society, 
gave him opportunities and scope for pursuing his inquiries—ultimately resulting 
in the publication of his laborious work on ‘The Geology of Yorkshire,’ a work 
not only abounding in local details, but containing the germs of several generali- 
zations on questions relating to physical geology. 
Of his connexion with the Geological Survey of Great Britain, Professor 
Phillips has left two enduring monuments in his work on ‘The Palzozoic Fossils 
of Cornwall, Devon, and West Somerset, and that on ‘The Malvern Hills and 
surrounding districts’*—one dealing with the organic structures, and the other 
more especially with the physical conditions of the south and west of England. 
To his future career as Professor of Geology in the University of Dublin, after- 
wards, on the death of Dr. Buckland, in the University of Oxford, or as President 
of the Geological Society of London in 1859 and of the British Association at Bir- 
smingham in 1865, itis unnecessary for me in this brief notice to do more than allude. 
‘Through these years and down to the time of his decease his fertile brain and 
ready pen were ever at work. But the scope of his investigations was not limited 
to purely geological subjects; he was a man of many parts, and astronomical 
questions largely engaged his attention in his later years. In 1868 he visited 
Italy and Vesuvius, and subsequently published a little work on the history and 
structure of that mountain in a form very acceptable to that large portion of the

May Hill, Tortworth, and Usk,” Mem, Geol, Survey, 1849, ai ' .
