196 SANGATTE. [1865. 



The Easter excursion, dating 14th April, was made 

 to Antwerp vid Harwich, when the three friends who 

 accompanied Prestwich were Captain Douglas Galton, 

 Mr J. Gwyn- Jeffreys, and Mr Godwin-Austen. 



To judge from the ground traversed, this expedition 

 to Belgium must have been of great interest. Our 

 geologist, as usual, was in search of Drift and Loess, and 

 intent on tracing the features of the Gravel deposits, 

 in which remains of elephants and other extinct 

 mammalia had been found, the observations of his 

 friends being quoted and interwoven in his voluminous 

 notes. When at . Lie'ge they saw the Schmerling 

 Collection ; and Prestwich noted " the Engis skull 

 very fresh -looking, so also some of the bear remains. 

 The Engis Cave worked out." 



They were joined at Louvain by M. Van Beneden, 

 and at Brussels by M. Nyst. Amongst other places 

 visited were Maestricht, the Engis Cave, Dinant, the 

 Grotte du Frontal, Namur, Mons, Spiennes, &c. It 

 must have been hard work to crowd so much practical 

 geology into a ten days' tour. To make the most 

 of their time, the journey from Marsieres to Lille 

 and Calais was by night train. One day was devoted 

 to an examination of Sangatte Cliff, to which Prest- 

 wich returned alone on the 24th. He was keenly 

 interested in the geology of the coast between Calais 

 and Sangatte, and in going back to the ground wished 

 to satisfy himself on points which to his mind had 

 not been perfectly clear. He was desirous of ascer- 

 taining the composition of the Raised Beach at Sangatte 

 the relative proportion of angular chert, pieces of 

 rolled red granite, lydian stones, and pebbles of sand- 

 stone, &c. 



How many visits were made to the Calais coast ?
