One day in October of last year while walking round by the Cloch, 
I happened to take a look at the rock sections seen near the 
shore in that neighbourhood. Being aware that the sandstone rocks 
exposed for a considerable distance along our coast line—that is 
south-westwards, from Greenock and Gourock—belong to the 
calciferous sandstone series, and being also aware that organic 
remains have been found in this series of rocks in different parts 
of Scotland, the thought often occurred to me that vegetable or 
animal remains might be found in the similar strata here. I was 
thus often tempted, while botanizing by the shore, to take a look 
at the rocks in passing, and on the day mentioned I examined 
some alternating beds of sandstone and shale exposed near the 
shore, ahout a quarter of a mile below the lighthouse. 
Some of the sandstones contained carbonaceous matter, which 
was quite structureless, but on carefully examining one of the 
beds of shale I found part of it crowded with vegetable remains, 
consisting for the most part of ferns and calamites—one species of
