In a previous contribution to the Geological Magazine the opinion was put forward, based upon an examination of field evidence available in the neighbourhood of Largo, that the assumption of a Permian age for the old volcanoes of East Fife should no longer be sustained. It will be remembered by those interested in the matter, that whereas this district afforded remarkably clear evidence of contemporaneous volcanic action during Lower Carboniferous times, no confirmation was forthcoming of Sir A. Geikie's wholly different structural interpretation of an overlying unconformable sheet of post-Carboniferous ash. The purpose of this paper is to supplement the conclusions arrived at three years ago, and to note one or two additional field exposures that seem likewise to indicate contemporary eruptive activity among the Lower Carboniferous rocks of East Fife.
