Of the Silurian slates at West 400 are exposed at the top of the hill where the horn has its origin. 50-75 fur About [illegible] the diabase sill seems a dimy sandstone abounding in Spirifus and other fossils some of which we familiar. Between the exposures seems to be Beech's. Possibly 300 further from some fossils are common though - only one of 50 to 100 far. Here the Spirifus are small associated with small Athyris on abundance of dents of, pupalana and [illegible] . This faunule is directly connected with the Beech's but the horizon may be in the upper New Scotland though I saw nothing to enable this correlation possible. Below this faunule and slaty the sandy nature of the bed continues to the base but the fossils if present are not
