places. The chalk cliffs of Dover, which 

 have played an important part in the de- 

 fense of England, are deposits composed 

 mostly of the shells of forams. The stone in 

 the Egyptian pyramids is made up of the 

 skeletons of very large forms of the genus 

 Carnerina (formerly Nummulites) . 



In various shore and deep-sea regions, 

 ooze of radiolarian origin is equally abun- 

 dant. Approximately 2,290,000 square miles 

 in the Pacific and Indian oceans are covered 

 by this material. Radiolarian ooze may be- 

 come sedimentary rock and may be buried 

 under other types of rock. Radiolarians, like 

 the forams, are of great importance to geolo- 

 gists.
