 local geology, facts as gathered from our immediate neighborhood. We 

 do not claim that the same state of things in all its minutia of details

 to hold good, and as time goes on we hope to apply it. While we admit 

 that possibly hereafter some of the above forms may be found penetra- 

 ting into the Hamilton proper, it is equally possible that with more 

 extended quarrying more new species will be discovered, confined to the 

 lower rock.
