CALCAREOUS BRECCIA CONTAINING fidNES. }Q5 



to adhere, was scattered about the bottom of the quarry in 

 large blocks. These blocks, when blown up, had left 

 large vacuities in their did place* in which were observable 

 a number of cavities five or six inches in diameter. 



This vast ledge is in the midst of a wood of wild and do- Situation of 

 mestic olive-trees, on the ridge, of the hill I have mentioned, the stratum 

 where it form 9 a sort of little mountain. It is surrounded 

 also by a number of blocks of stone, likewise calcareous; 

 some of which, having their angles broken off, appear to 

 have already undergone a change of place; while others 

 perhaps have come from the ledge itself, for there is no 

 doubt, that it was formerly more extensive, than when the 

 quarry was opened in il, since every thing indicates a derange- 

 ment of things in this place. This ledge, of a circular form; 

 rests principally On a bed of the same reddish brown earth, 

 perfectly resembling that which composes the columns, and 

 a blackish vegetable mould forms its base. The north and! 

 east are the two points, toward which the part wrought looks; 

 and that untouched faces the west y so that the whole ledge 

 forms a semicircle. 



On attentively observing this calcareous mas"s, I perceived Theintefpo-ed 

 that a number of little bodies, which Appeared to me ho- stone 

 tnogeneousj were embedded as it were in the brownish red 

 earth, and, being equal in hardness to the stone, induced 

 me to give it the name of calcareous breccia. I noticed 

 three different kinds of these small bodies : some of a ealca- fragments of 

 reous nature, and a rhomboidal figure, inserted in it in otoerswueqi 

 groupes; others of a refractory nature, with the aspect of a 

 ibliaceous granite, containing little lamina of mica in a 

 Btate of alteration; and lastly little round I6ng bones, perfo- 

 rated atone end, and destitute of spongy texture; which ap- a ndbon*s, 

 peared tb me tibias of some large bird or small quadruped. 

 Continuing my remarks; and desirous of being more fully 

 acquainted with the contents of this earth, I attempted to 

 break several block*, to get a good specimen. Not being 

 able to accomplish this without a great deal of trouble and 

 exertion, and my curiosity not being satisfied, I bethought 

 myself of recurring to the cavities and vacuities, which the 

 blowing up of the rocks had laid open. In fact by this 

 means I was more successful, and with less labour ; for
