Atlas photo graphique des formes du relief terrestre. Prepared by an 

 International Commission a quarto. Geneve (Suisse): Fred. 

 Boissonas et Cie. 



Part I of the first series of plates in this atlas has been issued and 

 distributed. In this part there are eight excellent plates chosen to 

 illustrate the land forms produced by rock disintegration and the action 

 of gravity. These plates were selected from a vast number of subjects 

 submitted by members of the International Commission appointed 

 by the ninth International Congress of Geographers. This com- 

 mission was directed to co-operate in the preparation of the most com- 

 prehensive atlas of relief forms of the earth that has ever been prepared 

 for publication. 



The burden of the work has fallen upon the three members of the 

 executive committee, Professors Jean Brunhes, Emm. de Martonne, and 

 Emile Chaix, and to these men much appreciation and praise is due 

 for the excellency and attractiveness of this first number. 



The plates included in this first part are the following: 



Plate I. — Disintegration controlled by structure (photographs by M. 

 Lugeon). Disintegration partly independent of structure (photographs by 

 Jean Brunhes, E. de Cholnoky). 



Plate 2. — Exfoliation of granite (photographs by G. K. Gilbert, H. W. 

 Turner) . 



Plate 3. — Exfoliation of granite (photographs by H. W. Turner, CD. 

 Walcott). 



Plate 4. — Peaks formed by frost weathering (photographs by L. Duparc). 



Plate 5. — Rock pinnacles (photographs by L. Duparc, E. Chaix). 



Plate 6. — Forms due to weathering in the "Dolomites" (photographs by 

 O. Lehmann). 



Plate 7. — Crumbling ridge in high mountain and in the polar regions 

 (photographs by E. Chaix, E. de Cholnoky). 



Plate 8. — Mechanical disintegration and chemical decomposition com- 

 bined (photographs by E. Chaix). 



Each plate is a phototype printed on special paper loX 13 3 inches. 

 It is accompanied by a description published in three languages, one 

 of which, in each case, is English. These plates and their descriptions
