 Describes Drift phenomena of the southernmost point in Lusatia to 

 which Drift reaches. It is found at a height of 400 metres above sea- 

 level, and consists largely of shingle of local rocks, in contrast with 

 that of the N. German plain, which consists of loam with erratics of 

 Scandinavian origin. In Lower Lusatia the Drift partakes of the latter 

 character. E. B. T.

 The Merville boring reached Chalk at 89 metres, that of Thumesnil 

 proved Tournai stone at 66 m. ; and at Hermies marls with Terehratula 

 gracilis were struck at 64 m. A section of the first boring is given.

 Two sections of railway-cuttings. The occurrence of Gallo-Roman 

 pottery about 3 metres above sea-level makes the author think that it 

 was brought by the waves of the sea. In the discussion Prof. Gosselet 

 differs, and thinks that in Gallo-Roman times Marck may have been 

 dry land when St. Omer was under the sea. G. A. L.
