28 Notices of Memoirs — Charles Moore. 



Boston is affected by two lines of upheaval, each marked by dykes 

 and by considerable dislocations of strata. With the direction of 

 these disturbances the lines of Drift exactly correspond, and Pro- 

 fessor Shaler concludes that these Drift-hills are only cappings of 

 glacial detritus lying upon ridges of the more solid rock of the 

 country ; the solid pedestal having prevented the wearing action of 

 the streams from affecting the detrital matter which rested upon 

 them. He concludes with some remarks upon the Glacial period. 



II. — The Mammalia and other Eemains from Drift Deposits in 



THE Bath Basin. 



By Charles Mooee, F.G.S. 



[A Paper read before the " Eath Natural History and Antiquarian Field Club." 

 8vo. Bath, 1870.] 



THE "Drift deposits" here described comprise the Alluvial beds 

 and Post-Pliocene gravels, due to the action of fresh water, and 

 which have been deposited in the valleys since the country assumed 

 the general physical configuration which it now possesses. Although 

 some of the derived materials have been brought from considerable 

 distances, in general they have been washed down from the higher 

 grounds, or from the sides of the valleys upon which the ancient 

 streams operated, in much greater volume than those which now 

 follow their courses. 



The area to which Mr. Moore's remarks are applied comprises 

 the low ground, west of Bath, and the valleys running immediately 

 out of it to the east, namely, those of Box, and that extending by 

 way of Limpley Stoke and Preshford to Bradford. 



He treats first of the Historic Period, mentioning the discovery, 

 at a spot twelve feet below the city of Bath, of two stone coffins, in 

 which he obtained a small collection of fossils, which had been 

 washed in. Mr. Moore shows that, subsequently to the Eoman 

 occupation, the area upon which Bath stands became a swamp, as 

 remains of this period occur covered up by mud, vegetable remains, 

 and drift wood, the deposit in some instances being almost converted 

 into peat. Mixed with it are many mammalian remains. He 

 explains, by means of well-sections, the characters and thicknesses 

 of the different deposits of Historic, Pre-Historic, and Post- Pliocene 

 times, which are met with in the vicinity of Bath, 



Under the term "Mammal Drift" are included all the gravel 

 deposits of the district. In it are found remains of Eleplias primi- 

 genius, E. antiquus, Bhinoceros ticJiorJiinus, Ovihos moschatus, Wild 

 Boar, Horse, Eeindeer, and Bos primigenius. No traces of Man have 

 as yet been determined. 



Mr. Moore gives lists of the land and freshwater mollusca, and 

 other remains from the different drifts, and he also records the 

 species of derived fossils which he has met with in them. Conclud- 

 ing with some theoretical remarks, he expresses his opinion that 

 evidences of glacial action occur in the deep and long-continued 

 furrows in the stiff Liassic clays on which the Mammal Drift now 

 lies. H. B. W.
