Vol. 6$.~\ ANNIVERSARY ADDRESS OF THE PRESIDENT. lxix 



Chamber of Commerce. But, while thus fully immersed in mer- 

 cantile pursuits, he found time to cultivate the taste for natural 

 history which he had shown from his boyhood. It appears to have 

 been after the year 1886 that he gave his special attention to 

 geology, for he then inherited the geological collection and library 

 of his uncle, W. H. Leighton. It was chiefly among the Cretaceous 

 and Tertiary formations that he found scope for his work in the 

 field. He communicated to the Society a paper on ' The Lower 

 Greensand above the Atherfield Clay of East Surrey,' which 

 appeared in the volume of our Quarterly Journal for 1895. He 

 also wrote papers on the same subject and district in the ' Proceed- 

 ings ' of the Geologists' Association, likewise on the Greensand and 

 Tertiary series of the Isle of Wight and on the Barton Beds of the 

 Hampshire Coast. He acted as Excursion Secretary to the Geolo- 

 gists' Association for the six years from 1890 to 1896, and was 

 indefatigable in his attention to the duties of that office. He was 

 elected into the Society in 1S91. His death took place suddenly 

 on November 10th, 1906. 



The Geological Society having watched with interest and sym- 

 pathy the foundation and vigorous growth of a younger institution 

 devoted to the same scientific aims with itself, I may express our 

 sincere regret that the Geologists' Association should have lost 

 in Percy Emary its indefatigable Secretary, who for nine years 

 devotedly watched over its progress. He was elected a Fellow of 

 the Geological Society in 1897. If he has left no record of original 

 scientific work, the yearly volumes of the Association for which he 

 laboured so hard will remain an enduring monument of his services 

 in the cause of geological advancement.
