epochs of the elevatory movements, and other phe- 

 nomena of which this remarkable island is a memorial, 

 do not appear to have been stirred at all. The Com- 

 mittee cannot presume that all deficiencies are now 

 supplied, but they are certain that many points formerly 

 obscure have been illustrated by their labours, and 

 that a foundation at least is laid for a very complete 

 and singular geological monograph. Their specimens, 

 amounting probably to 700 or 800, have been selected 

 with much care, 1 many sections have been drawn, a 

 large map is in progress, and they have every hope 

 that the model will, when finished, answer the purpose 

 of rendering a great class of phenomena more palpable 

 than could be done by any other mode of representa- 

 tion. It is necessary to mention that a new survey of 

 the island in every locality has been executed, and that 

 nearly all these labours have been gratuitously per- 

 formed by their secretary, Mr. Andrew Ramsay, to 

 whose talent and untiring energy their success is 

 wholly owing.' 



By the time the Association met, these active pre- 

 parations had been completed. The specimens from 

 Arran, after much anxious consultation over them on 

 the part of Professor Nichol and his young associate, 

 were duly displayed, the large map and sections were 

 hung up, and the model, on the scale of two inches to 

 a mile, was exhibited, with all the geological formations 

 of the island clearly depicted on it in distinct colours. 



A notable gathering of geologists assembled in 

 Glasgow in September 1840. They included Lyell, 2 



1 These specimens became the property of the British Association, and were 

 handed over to the Andersonian University of Glasgow. But many years 

 afterwards (1876) the Andersonian authorities, having no longer room for them, 

 returned them, and they are now in the British Museum.
