lvi PROCEEDINGS OE THE GEOLOGICAL SOCIETY. [vol. lxxiv, 



The paper on the raised beach of South Wales directed attention 

 to a phenomenon which is now recognized as of very high 

 importance. 



Of Tiddeman's personality little need be said : words addressed 

 to his friends would be unnecessary, and to others inadequate. 

 Suffice it to say that in him an absolutely upright character was 

 combined with singular charm of manner, and that those who knew 

 him loved and respected him whole-heartedly. [J. E. M.] 



Geoege Alexaxdeb, Loins Lebour was the son of French 

 parents, his father, Alexander Lebour, being an artist of distinction. 

 He himself was born in France, at St. Omer, in 1847; but at the 

 age of two years, owing to a pending revolution, his parents brought 

 him to England, where they settled, and he was educated as an 

 English bov. Even in his childhood he was an enthusiastic col- 

 lector of fossils, and it was his great ambition to become a geologist. 

 After he left school he Avas for some time employed at a mercantile 

 house in the City ; but the work was so entirely distasteful to him 

 that at last he was allowed to follow his natural bent, and lie 

 entered the Royal School of Mines, where he came under the 

 influence of Ramsay. In 1867 he obtained an appointment upon 

 the Geological Survey, and was sent to join William Toplev at 

 Morpeth in Northumberland. His Avork upon the Survey lay for 

 the most part in that county, and it A\ T as this circumstance that 

 determined the Avhole course of his future career. 



David Page, who was at that time Professor of Geology at the 

 newly-founded Durham UniA^ersity College of Physical Science in 

 NeAvcastle-on-Tyne, had become so infirm that it Avas necessary 

 to proA T ide him Avith some assistance ; and in 1873 Lebour was 

 appointed Lecturer in Geological Surveying. But, from the first, 

 more of the work than the title implies fell to his share, and. on 

 the death of Dr. Page in 1879. he became Professor of Geology, a 

 post AA r hich he held for the remainder of his life. During that 

 period of nearly 39 years he took a large part in the development 

 of the institution from its small beginning to its present position, 

 under the name of the Armstrong College, as one of the largest 

 and best-equipped of the provincial Colleges ; and since 1902 he 

 had been Vice-Principal. 



His published papers number more than a hundred; but they 

 are widely scattered through many periodical publications, both 

 English and French, and only two appear in the Quarterly Journal
