88 THE COMING OF AGE OF 



presidential address to the Geologists' Association, delivered 

 February 8th, igoi, under the title " Twelve years of 

 London Geology " {Proc. Geol. Assoc, XVIL, 8i). While dealing 

 with Mr. Whitaker's contributions to our publications I may 

 point out that in 1887, in a paper entitled " What is the use of 

 the Essex Field Club?" (Essex Naturalist, L, 180), he 

 emphasized in his forcibly humorous style the necessity for the 

 members of a local society such as this looking out for temporary 

 sections exposed by railway cuttings, &c. In i88g Mr. 

 Whitaker, in conjunction with Mr. Dalton, contributed a most 

 valuable bibliographical paper to the Essex Naturalist (III., 

 61-86), viz., a '■ List of Works on the Geology, &c., of Essex," 

 this list comprising the Geological Survey PubUcations, and 

 books, papers, &c., chronologically arranged from 1701 down to 

 1888. In the same volume (p. 140) he sanctioned the publica- 

 tion of an abstract of a paper " On a Deep Channel of Drift in 

 the Valley of the Cam, Essex " read at the Newcastle meeting 

 of the British Association, and since published by the Geologi'ial 

 Society {Quay. Jotirn., i8go, p. 333 ; Essex Naturalist, IV., 

 117). 



The Rev. A. W. Rowe, who has since made notable con- 

 tributions to geology, gave us in 1885 a paper on some 

 crystalline rocks from the Drift in the neighbourhood of Felstead 

 (Proc. IV., cxl.) which, after further elaboration, was published 

 in extensc by the Geological Society [Qiiav. Jouvn., Aug., 1887, 

 pp. 351-363). A later contribution on Essex boulders was made 

 by Mr. Rowe in 1887 (Essex Naturalist, I., 117) in extension 

 of a note on this subject by Mr. Worthington Smith [Ibid., p. 8). 



The contributions to Essex geology with which our publica- 

 tions have been enriched by the work of Mr. T. V. Holmes are 

 so numerous and important that it is only possible to do justice 

 to them by giving a special list : — 



" On the Subsidence at Lexcien, near Colchester, in 1862." Essex Nat., 



I., 1-8. 

 " Notes on Drift Maps, with special reference to those of Essex." Ibid. II., 



21-32. 

 "The Subterraiiean Geology of South-Eastern England"; Presidential 



Address for 18S8 ; Ibid. II., 138-158. 

 " Notes on the Geology of Maldon and the Blackwater Estuary " ; Ibid
