Letter to Sir Archibald Geikie from PB Brodie discussing differences between the liass formations (jurassic) in Gloucestershire and Skye. He reports that there is no sandstone in Gloustershire. He describes some fossils he has found and a liassic reef covered with grass. He reports that he will be sending some specimens to the Museum of Economic Geology and would appreciate any samples which Geikie could spare. He adds a post script that he has lost a ticket sent by Geikie and requests a replacement.
