The President suggested the possibility of some of the minute 

 Foraminifera being transported fossils derived from earlier beds than 

 those in which they are now found. 



Dr. Carpenter observed that the mode of examination to be 

 adopted with Foraminifera was different in character from that which 

 was aj^plicable to higher organisms. The range in variation was so 

 great that a comparatively imperfect examination of Xummulites had 

 sufficed to make M, d'Archiac reduce the number of species by one 

 half; and all the speaker's subsequent studies had impressed upon him 

 the variety in form and in sculpturing of surface on individuals of the
