Society. Among them was his elaborate account of the strati- 

 graphy of Devon, which he was induced to undertake at the request 

 of Murchison. Jukes had at that time promulgated certain views, 

 which the Chief looked upon as heretical, regarding the Devonian 

 system, and the Survey-Pakeontologist was deputed to test their 

 accuracy. He spent many weeks on the ground, and came back 

 to support what had long been the orthodox faith. The world has 

 not accepted the contention of Jukes. Xo one, however, who has 

 attempted to understand on the ground the succession and tectonic 

 relations of the Devonian rocks of Devon and Cornwall, can fail 

 to be convinced that whether the accepted view as to the order 

 of succession shall ultimately be established by detailed mapping 

 or not, it was certainly founded in ignorance of the extremelv- 

 complicated structure of the region. Even yet, after all these years 

 of patient investigation, reinforced more recently by the minute 

 iield-researches of the Geological Survey, the stratigraphy of that 

 region of the country is far from having been unravelled and 

 understood. 



Other papers by Etheridge during his Survey-career, to which 

 reference may be made here, are his account of the Dolomitic Con- 

 glomerate of the Bristol area, and more particularly his two Presi- 

 dential Addresses to this Society, embracing as they did an enormous 

 mass of detail which, though of temporary interest, has now little 

 more than a historical value. His position at Jermyn Street made him 

 an official referee, to whom specimens of fossils from all parts of the 

 world were submitted for determination. A number of his reports 

 on these were submitted to this Soeietv, and are to be found in our 

 Quarterly Journal. As a notable example of the laborious tasks 

 which he undertook, allusion may be made here to his strati graphical 

 and zoological ' Catalogue of British Fossils,' wherein he attempted 

 to give the position of each species in the geological formations, in 

 systematic grade, and in scientific literature. Only the Palaeozoic 

 portion of this work has been published, the Mesozoic and Kainozoic 

 portions remaining still in manuscript. These and all the other 

 similar works of Etheridge bear witness to his remarkable neat- 

 handedness. Page after page and table after table may be seen 

 clearly written out, with few or no corrections, and now and then 

 accompanied by a cleverly-drawn and coloured geological section in 

 illustration of some question of stratigraphy. 



In 18S1 Etheridge quitted the Geological Survey to accept the 

 })ost which was offered him of Assistant-Keeper of the Geological
