The severed portions of land still legally belong to the Riding 
and parish, of which they were originally a part, thus showing 
that the solid crust of the earth may change sooner than 
parochial conservatism. 
I have thus endeavoured to give an account of the appear- 
ances presented by the strata of the district in which I reside, 
so far as I have been able to ascertain them ; but I can only 
guess at the way that they have^been formed, and must leave 
the explanation of their origin to more experienced geologists. 
Our secretary suggests that a microscopic examination 
of the sands and clays might possibly throw some light upon 
their origin. The time at my disposal has, however, been 
insufficient to allow me to do anything in this direction. 
Should I have opportunities in the future I will work at the 
subject, and if I obtain any results worthy of your attention I 
will bring them before you in another communication.
