ward, intent on working out some special points, and 

 after two days of solitary exploration of the hills 

 between Skiptoii and Lotherdale, as usual in quest 

 of " Drift," on the 2nd April he joined Professor Boyd 

 Dawkins and Mr R. H. Tiddeman of the Geological 

 Survey, at the New Inn, Clapham, in the West Riding 

 of Yorkshire, which was made their headquarters. He 

 had visited the Victoria Cave at Settle, at least once 

 before, but the first day's work was a re-examination 

 of it and of two small caves near. The Cave at Ingle- 

 borough was also explored. On this interesting ex- 

 cursion Prestwich was busily engaged with his two 

 companions in noting every occurrence of boulders, of 

 Boulder Clay, or traces of Drift or of ice- act ion, in the 

 districts of Selside, Long Preston, Whalley, and Hoi- 

 combe, &c. 



Early in May his great paper on " Deep Sea 

 Temperatures" was handed in to the Royal Society. 

 It was read on the 18th June, a week later than the 

 date on which another of his papers was read at the 

 Geological Society, entitled " Notes on the Phenomena 

 of the Quaternary Period in the Isle of Portland 

 and around Weymouth." Into this latter were woven 

 many of the observations made during his sojourn at 

 Weymouth (see p. 242). 



During this year also, a translation into French of 

 his memoirs on the Crag ' La Structure des Couches 

 du Crag ' - - was published by M. Michel Mourlon, 

 Docteur-es-Sciences at Brussels. 



But 1874 was a year memorable in the life of Joseph 

 Prestwich, the one in which he agreed to become 

 the successor of the deeply regretted Professor John 

 Phillips, and to fill the Chair of Geology at Oxford.
