lxii PROCEEDINGS OE THE GEOLOGICAL SOCIETY. [May I909, 



ornithology, and was thus led to make long journeys over many 

 parts of Europe and Northern Africa. From 1862 to 1867 he 

 devoted himself to the systematic study of natural science, first 

 at Edinburgh and afterwards at the E,oyal College of Chemistry 

 in Oxford Street. He was almost equally attracted to chemistry 

 and geology, and the choice of geology for his life's work was due 

 to a chance meeting with Marshall Hall at Chamounix in 1866 ; 

 this led to his acquaintance with John Morris, whose attractive 

 enthusiasm proved irresistible, and in 1867 he was elected a Fellow 

 of this Society. Hudleston's inclination was towards open-air 

 geology, he was an ardent worker in the field, and did much to 

 organize the excursions of the Geologists' Association : of this body 

 he became a member in 1871. Three years later he became its 

 Secretary, and drew up reports of its expeditions which abound 

 in original observations. His earliest published papers were the 

 ' Yorkshire Oolites,' which appeared between the years 1873 and 

 1878. His first communication to the Geological Society, made 

 in association with J. F. Blake, was a very important memoir on 

 the ' Corallian Ptocks of England.' This masterly work is the first 

 complete treatise on the beds which lie between the Kimmeridge 

 and the Oxford Clay in this country. 



In 1881 he was elected President of the Geologists' Association, 

 and during his term of office delivered two addresses, one on 

 ' Deep-Sea Investigation ' and the other on ' The Geology of 

 Palestine.' Each is a short but complete monograph, admirably 

 succinct and clear. 



In 1884 Mr. Hudleston was elected a Fellow of the Royal 

 Society; in 1886 he was elected one of the Secretaries of the 

 Geological Society, and in 1892 became President. The Geologists' 

 Association made this the occasion of a congratulatory address, in 

 which Mr. Hudleston was spoken of as the Association's 'best 

 friend.' His addresses were devoted to an exposition of the recent 

 work published in our Journal, the first treating of the Cainozoic 

 and Mesozoic Eras, and the second of the Palasozoic and Funda- 

 mental Bocks and certain general questions. It was a difficult and 

 delicate task ; as he remarked, ' not unlike that of a man who 

 tries to lift up a beehive ' : needless to say, it was accomplished 

 Avith perfect judgement and good taste. These valuable resumes 

 suggesb the question whether addresses of the same nature ought 

 not to be expected from the Presidential chair, say once in every 

 decade.
