Extract

A RECENT communication from Mr. E.H. Davison relating to the possible age of the “ Lundy Island granite ” is interesting as affording several points of contrast with the results of detailed researches in structural and petrological characters of this some-what inaccessible island in the Bristol Channel, which the author has been carrying out for some time.
