The Pyrenees. The Winter Session in this Section opened on 

 November 22nd, 191 1, when a paper was read by Dr. 

 Colley March, F.S.A., Vice-President of the Dorset Field Club, 

 entitled " Odds and Ends from the Eastern Pyrenees — Geological, 

 Glacial, Neolithic." After a brief description of some of the lead- 

 ing geological features of this mountain range, Dr. March 

 described a neolithic floor which he had discovered, and exhibited 

 various objects of human workmanship found there. Some account 

 of the glaciation of the district was also given, and some geological 

 and other specimens were shown. 



Flints. On December 16th, 191 1, a lecture was given 



by the Chairman of the Section on " The Origin 

 and Formation of Chalk Flints." This was illustrated by lantern 

 slides of micro-photographs from sections of various kinds of flint 

 and chert, which had been lent by Mr. William Hill, F.G.S., late 

 President of the Geologists' Association, and used by him to 

 illustrate his presidential address to the Association in February, 

 191 1. Dr. Ord explained that Mr. Hill's address on Flint and 

 Chert * gave the latest views as to their origin and formation, and 

 it was frequently referred to in his lecture. A number of micro- 

 scopic sections of flints were shown, also hand specimens of 

 various types from the neighbourhood, as well as from Dr. Ord's 

 collection and the cabinet of the Society. 



The Chalk Sea. On January 18th, 1912, a lecture was given by 

 Mr. H. St. Barbe, of Lymington, on " The 

 Chalk Sea." This was of special interest, both for the clear 

 account given of the geographical and physical conditions under 

 which the present chalk formation was produced, and also in re- 

 ference to the previous lecture by the Chairman on flints. Mr. St. 

 Barbe showed various diagrams illustrative of his subject. 



Jersey. On May 4th, 1912, a paper on the Geology of 



the Island of Jersey was read by Dr. G. E. J. 

 Crallan, Dr. Ord being in the chair. The paper was illustrated
