Establishes the presence of bands of phosphatic nodules in small 



outliers of Gault, refers their origin to the action of mineral springs, 



and notices the small size which obtains with regard to the fossils of 



the Gault generally. A list of the Albian fauna of the Cote d'Or is 



given. G. A. L.

In 22 centuries the Rhone delta has run out 26 kilometres into the 

 sea. The progression has not slackened its pace in modern times. The 

 Grand Ehone has formed the Camargue, whilst the Petite Camargue 

 (the Aigues-Mortes tract) is due to the Petit Rhone and the Durance. 

 In the latter district old shore-lines are recognizable. The writer 

 traces, by means of historical documents and topographical evidence, 

 the changes which have taken place in this part of the delta, shows 

 that when St. Louis embarked at Aigues-Morte that town was not on 

 the sea-coast, and was only connected with it by shallow lagoons. The 

 routes from that town to the coast followed by that monarch and by 

 the Emperor Charles Y. after him are shown on the map. A copy 

 t)f part of a map of the region, dated 1591, by Jean Bompar, is also 

 given. G. A, L.

 (Espagne). [Metalliferous deposits of the district of Carthagena, 

 Spain.] Ann. Soc. Geol. Belg. t. ii. Memoires, pp. 58-107, col. plate. 

 . The Introduction gives an historical account of the Mining Industry 

 of the district. Chap. i. describes the geology of the district, which is 

 of a very disturbed character. The metalliferous zone is formed of 

 schistose and calcareous Permian rocks ; outside this zone are Tertiary 

 and Quaternary conglomerates, often cut through by trachytes and 

 basalts. Chap. ii. treats of the ore-deposits, which are described under 

 the following heads : — A. Silicate of iron deposits, forming'a thick per- 

 sistent bed in the schistose or lower portion of the Permian rocks ex- 

 posed (Middle Permian). B. Blende deposits, in beds higher up in 

 the same schists, but not so constant as the Iron-siHcate. C. Hy- 

 droxide of Iron, in beds higher up still in the same series. Under this 

 head are described deposits of carbonate of iron, plumbiferous hy- 

 droxide of iron, and argentiferous clays, which occur in similar geological 

 positions. D. Galena, in pockets, reniform masses, and crystalline
