of fossil - bearing limestone, whence at the spot marked + were 

 obtained remains of Mollusca, Echinoidea, and Foraminifera, which, 

 according to the determinations by Dr. Bather and Mr. R. Bullen 

 Newton, suggest a Middle Eocene age for the rock. This spur was 

 evidently more resistant than the promontory; it was less than 

 200 feet thick, and between it and the general plain level below lay 



another stratum of laterite, while the limestone itself was markedly 

 stratified. Similar discoveries of fossils ascribed to the Middle 

 Eocene period have been made bj' the French at Zinder, some 

 SOO miles to the east of Garadimi, and have been commented on by 

 Professor A. de Lapparent.
