An interesting episode was the reading by the secretary- 
general, jVI. Barrois, of a passage from a note by M. Walcott, 
director of the U. S. Geol. Survey, on "Fossiliferous pre-Cam- 
bric formation," in which, relying on the testimony of M. 
Ranff, he doubts the existence of the organisms described by 
AI. Cayeux in the pre-Cambric of Brittany. After the reading, 
M. Rothpletz stated that with M. Renard he had seen the sec- 
tions described by M. Cayeux and considered the existence of 
the Radiolaria in these preparations indubitable.
