KOCKS OF SOUTH DEVON. 489 



beneath the limestones.'' Unfortunately, subsequent investigations 

 near Cockiugton, Marldon, and Paignton induced Mr. Champer- 

 nowne to abandon his previous views and to endorse, on strati- 

 graphical grounds, the erroneous succession given by Dr. Holl. The 

 independent observation of the Plymouth section led me to adopt 

 the same views. We were both under the impression that the 

 Cockiugton beds were unfossiliferous, and in ignorance of the dis- 

 covery, b} the Eev. G. P. Whidborne, of Lower-Devonian fossils in 

 them, no detailed account of which had been published beyond 

 incidental reference to it in Dr. Davidson's Supplement to Devonian 

 Brachiopoda, Pal. Soc. Mon., note by G. F. W. at p. 4. 



Thus, through a mere accident, the geologist whose painstaking 

 devotion has furnished the first detailed map of the Devonian rocks 

 of South Devon, and vastly increased our knowledge of that forma- 

 tion, was deprived of reaping the results of his exhaustive labours. 



For the publication of the erroneous succession given in Proc. 

 Geologists' Assoc, vol. viii. pp. 442 &c., I am alone responsible, 

 Mr. Champernowne's views having, at my request, been promptly 

 reduced by him to their simplest form in spite of the uncertainty he 

 entertained respecting them. 



The existence of contemporaneous volcanic action, — the definition 

 of the Ashprington series and of sporadic evidences of local vulca- 

 nicity outside its borders, — the correlation of the Ashburton lime- 

 stone with that of NeAvton and Ipplepen, — and palseontological 

 contributions, adding to our knowledge of the Middle and Lower 

 Devonian, stand prominently forth amongst the labours of my 

 deceased friend. Had he lived, the task I briefly and inadequately 

 undertake would have fallen into better hands. 



During our friendship I became so thoroughly conversant with 

 the special difficulties he encountered, and with the doubts he 

 entertained, that, when it devolved upon me to carry on his work 

 on the six-inch Map, I started already equipped wath the results of 

 his experience, and was stimulated to researches in quest of fossils 

 in beds before regarded as unfossiliferous in character and anomalous 

 in position. So the present communication must be taken as the 

 outcome of my friend's Jife-work in Devonian geology, and will, I 

 trust, form a not unfitting tribute to his memory. 



After the London Meeting of the Geological Congress in 1888 1 had 

 the advantage of conducting MM. Gosselet, Kayser, Tschernyschew, 

 Hoist, and Freeh over the jSTorth-Devon section and over those parts 

 of South Devon near Kewton- Abbot, Chudleigh, and Torquay, which 

 would in a short time best show the different varieties of rock and 

 evidence of their fossil contents. 



Dr. Kayser embodied the results in a pamphlet entitled " Ueber 

 das Devon in Devonshire und im Boulonnais," JSTeues Jahrbuch fiir 

 Mineral. &c. Bd. i. (1889). The identification of the Cypridinen- 

 Schiefer, by the Lewell-Path road and at Whiteway Farm, was of 

 immense service to me. The identification of the Hope's Nose thin 

 limestone with the Calceolen-Kalk, and the correction of Mh. cuhoides 

 to procuhoides, were also important.
