This halibiolitliic formation also seems to be of Cretaceous 

 age, as stated by Ehrenberg. M. P. E. Botta published some 

 geological observations on the Libanus and Antilibanus in 

 1833 (4to, Paris) ; but Eussegger's ' Eeisen in Europa, Asien, 

 imd Afrika, &c.' with Atlas, 1841-42, is the only work we have 

 been able to refer to for a section of the Antilibanus. Eussegger 

 explains the structure of that range to consist of:' — (1) near 

 Baalbec, Upper Chalk, covered here and there with Tertiary 

 beds ; (2) flanking liilLs, reaching to a considerable height, of 

 Lower Chalk and Greensand, rising up from the west, and 

 resting on the (3) hard anticlinal Jurassic rocks of the lofty 

 central range. On the eastern side, the same succession of 

 strata, in reverse, dip away one after the other among the low 

 flanking hills, and the Upper Chalk disappears under the
