Administrative / Biographical History
There is an entry in the notebook relating to a British Association meeting in Glasgow, September 1876. The entry details an excursion where the party drove West out of town. They visited a water reservoir and examined limestones and trap rocks. Tawney collected specimens of amygdaloidal trap with Laumontite [zeolite mineral]. They then went to Ballaghan Spout [waterfall]. Tawney mentioned that the lowest Carboniferous beds at this locality are the Calciferous Sandstones. The party then visited Finnich Glen hollowed out of nearly horizontal ORS strata. The next day, the party travelled to Paisley by train and then drove out to Beith (as there were no Sunday trains). There they visited Limekiln quarries. Tawney collected a specimen of Gleniffer porphyry [Renfrewshire]. At Beith the Gateside quarries are about 1 mile from the town.
