ejected. The principal direction of the veins and pipes is N.N.W. All 

 these accumulations are referred to geyserian action towards the close 

 of the Eocene period. G. A. L.

 The chief conclusions are : — 1. Rise of the land and conse(]uent 

 retreat of the sea to the S. at the close of Miocene times ; 2. There 

 never was a Pliocene sea near Lyons ; 3. All the marine fossils found 

 in the Drift and alluvia are rolled fossils of the U. Miocene of Pongons, 

 near Hauterive ; 4. These deposits may he called glacial, as they can 

 be referred to the time of the formation and extension of the ancient 

 Alpine glaciers ; 5. The Erratic Drift occurs at a mean height of 300 

 metres. G. A. L.

 The areas of accession and discharge of the ancient glaciers of the 

 Rhone and Rhine were nearly equal. The Jura glaciers served as 

 relays to the Rhone glacier. At Calandra erratic blocks have been left 

 at a higher level than that reached by the glacier further back. There 

 was a continuous mass of glaciers from Central France to the Danube, 

 resembling the Greenland or Spitzbergen ice-sheets. W. H. D.

 higher and broader than now.
