and some 25 types are enumerated. Flint knives are next 

 considered. Large implements of arrow-point or spear-head form 

 are described, and the making of arrow-points is shown. Sixty- 

 five plates and 201 text-figures are devoted to the illustration of this 

 valuable memoir. It is impossible to give an adequate idea of the 

 beauty and excellence of the illustrations, but we commend 

 Dr. Wilson's memoir to all who are interested in the subject of 

 Prehistoric Archaeology.

June 20, 1900.— J. J. H. Teall, Esq., M.A., F.E.S., President, in 



the Chair. 



The President announced that the Foreign Secretary had i*eceived 

 the following letter from Professor A. Gaudry, F.M.G.S., President 

 of the Organizing Committee of the Eighth International Geological 

 Congi'ess : — 



"My dear Friend, — We have just published the Guide-book to 

 the excursions in France of the International Geological Congress. 

 It occupies over 1000 pages, and is full of beautiful illustrations and 

 of geological sections and maps. The excursions will extend over 

 the whole of France from the North as far as the Central Plateau, 

 the Alps, and the Pyrenees. As you are the Foreign Secretary of 

 the Geological Society of London, equally honoured and loved iu 

 England and in France, I think that no one is in a better position 

 than you to beg of the Fellows of the Geological Society of London 

 to come in large numbers to Paris. All our geologists will be 

 honoured in seeing them, and will be happy to receive their 

 opinions. To have any great authority it is necessary that an 

 International Geological Congress should have your country — 

 where Geology has been so magnificently studied — largely repre- 

 sented. You can tell our brethren of the Geological Society of 

 London that the President of the Organizing Committee of the 

 Congress of 1900 is the oldest of the Foreign Members inscribed 

 upon their list, that he is a former recipient of the WoUaston Medal, 

 a Foreign Member of the Koyal Society of London, and that among 

 his scientific acquaintance he has not a better friend than you. 

 This will be as much as to tell them that I am attached to them 

 by the bonds of deep gratitude, and that it will be a happiness for 

 me to welcome them in our ancient city of Paris. I reckon upon, 

 you. — Yours most sincerely, Albert Gaudry."
