If an apology were needed for writing a few words upon the subject of the fossil fish of the Lebanon, mine would be this, that I have resided so near the well-known localities as to be able to visit them often and collect more and better specimens than have ever been found there before. Many and celebrated geologists and palæontologists have written upon the subject of the fossil fish found here, and yet the localities have been visited by few of those who have written best. The distinguished palæontologist F. J. Pictet published a volume in 1850, and another, together with M. Alois Humbert, in 1866, in which are found interesting histories of the localities Hâkel and Sahel Alma, and most excellent and accurate descriptions and figures of the fossil fish found there up to the last date mentioned.
