Similar shifts in the strata are alluded to in the territory 

 of Polistena, where there appeared innumerable fissures in

 in parts the level of the corresponding sides was greatly

 ground. It was compared by the Academicians to a great 

 tooth half extracted from the alveolus, with the upper part 

 of the fangs exposed. (See fig. 111.) 



Along the line of this shift, or ' fiiult,' as it would be termed 

 technically by miners, the Myalls were found to adhere firmly 

 to each other, and to fit so well, that the only signs of their 

 having been disunited was the want of correspondence in the 

 courses of stone on either side of the rent.
