458 THE GEOLOGIST. 



Originally, then, the dike must have been situated somewhat as is shown at 

 a b, in Fig. 3, which is drawn on the scale of half an inch to the foot. The 

 limestone in front, that is on the left in the figure, is supposed to be restored.

It happens that a considerable part of the outer, that is the eastern, or shall 

 I call it seaward, wall of the fissure was removed, in the ordinary course of 

 quarrying, upwards of twenty-two years ago, so that the northern end of the 

 face of the dike, or more correctly, every part of it, excepting about three feet 

 in width, of its southern end, was revealed at that time, and in its face, thus 

 exposed, lay several fine bones quite open to the day ; one in particular, the 

 left ramus of a lower jaw bristling with teeth, a most tempting-looking relic of, 

 probably, the cave-hysena, not only failed to attract the attention of the work- 

 men at the time, but all its efforts to bring itself into notice were utterly 

 fruitless during twenty-two years. We will hope, for the credit of all whom it 

 may concern, that it was somewhat less conspicuous before it was washed and 

 bleached by the rains and sunshine of nearly a quarter of a century.
