 The rocks of these districts are described stratigraphically and litho- 

 logically, the chief divisions recognized being : — The Bottom rocks, con- 

 sisting of typical gneiss and of micaceous and quartzose schists ; the 

 Tromso mica-schist group, probably of Lower Cambrian age ; the 

 Balsfjorden schists, supposed to be of Upper Cambrian age ; the Raipas 

 series, which is probably the equivalent of the Hekla-Hook group of 

 Spitzbergen (Silurian or Devonian) ; the Gaisa system of Dahll 

 ( = Upper Golda group of Pettersen). Among the igneous rocks are : — ■ 

 Gneiss Granite, Inland Granite, Gabbro and Hypersthenite, fine-grained 

 Greenstone, Olivine rock passing to Serpentine, and Serpentine proper.

 Describes the courses of the numerous ancient glaciers of the district 

 and the moraine-deposits left by them. Ascribes the former alternating 

 extension and retrogression of the Pyrenean glaciers to oscillations of 

 the sea-level, which, by furnishing a greater or less surface for evapo- 

 ration, furnished more or less humidity for the production of neve. 

 The presence of a Saharan sea likewise influenced the size of these 

 glaciers in this manner. The pala3olithic deposits of the Gourdan cave 

 are described, the more recent being characterized by reindeer-bones, 

 and the older by those of the aurochs. The implements found are de- 

 scribed. The contents of the Lortet cave are enumerated. From the 

 evidence adduced, the author concludes that in reality the Reindeer age 

 is that part of the Quaternary period during which the mountaineers 

 of Southern France were addicted to sculpture and engraving ; it was a 

 calm long epoch, during which the glaciers, already retreating at its 

 commencement, continued to melt away, and the great Quaternary 

 animals disappeared one by one. G. A. L.

The origin of the Loess is ascribed to the disintegration of the Swiss 

 Mollasse at the time of the melting of the great Alpine glaciers. The 

 existence of Quaternary glaciers in the Vosges and in the Black Forest 

 is thought doubtful. G. A. L.
