To quickly assess the difficulty of the text, read a short excerpt:
THE PABBA SHALES. The Pabba Shales represent the main of the Charmouthian, but the highest beds of these shales are of vald-ani date. So there is either a hiatus or unexplored ground between them and the base of the Scalpa Sandstone dated as pie-Oistcceras ; but the base of the sandstone may be earlier the evidence about its zones is quite meagre. The upper third of the Pabba Shales coincides in a general way with the Pyritous Shales of Yorkshire and with the Stonebarrow or Belemnite Beds of th...e Dorset Coast. The lower two-thirds are a very much ex- panded representative of the top portion of the Siliceous Shales of Yorkshire the part assigned to the zone of raricostatus, upon which more will be said later. It is doubtful if the Ironstone Shales of York- shire are represented by the top of the Pabba Shales, for there is a faunal difference. Yorkshire lacks the valdani fauna above jamesoni, but shows a Polymorphites fauna ; the Scottish deposits show the former but lack the latter. The true sequence is perhaps to be expressed as valdani.
