metamorphism; granites and granulitic gneisses; diorytes and amphi- 
bole gneiss; surface eruptive rocks, both Precambrian and Silurian; 
Laccoliths and Carboniferous dikes; aplytes and kerzantons; approxi- 
mate cost 220 francs. 
8. In the Tertiary Paris Basin. Four different short excursions 
will be made on those days intervening between the sessions of the

Boulonnais will lead to a visit to the ''Primary" terranes, to the 
Jurassic and Cretaceous, and to an examination of the general suc- 
cession of fossiliferous horizons, the tectonique, the folding rnd the 
planation of Lower Boulonnais, costing about 90 francs. The sub- 
excursion in Normandy will lead to the study of Cretaceous and Jur-
