Strathbogie of two identical igneous sequences, separated by an 

 epoch of intense earth-movement. The outstanding feature of 

 Mr. Read's petro graphical work, and one that will undoubtedly lead 

 to still more important developments, is the evidence which he has 

 been able to produce from the igneous rocks of Banff and Aberdeen 

 of the great part played by assimilation-processes in petrogenesis. 



May I ask you, in transmitting this award to Mr. Read, to. 

 assure him of our R'ood wisbes for further success in the future ? 



AWARD EEOM THE MtTECHISOjS GEOLOGICAL FUND. 



In presenting the Balance of the Proceeds of the Murchison 

 Geological Fund to Mr. Thomas He>~bt Withers, F.G.S., the- 

 Peesident addressed him in the following words : — 



Mr. Withers, — 



The curious group of highly specialized Crustaceans known as; 

 Cirripedia is of particular interest to British naturalists as having 

 formed the subject of two monographs by Charles Darwin, on the- 

 recent and fossil forms respectively. Darwin worked steadily on 

 his ' beloved barnacles ' for eight years : in his autobiography he- 

 wrote : ' I do not doubt that Sir E. Bulwer-Lytton had me in mind 

 when be introduced in one of his novels a Professor Long who had 

 written two huge volumes on limpets.' Since Darwin's clay but 

 little work had been done on the fossil representatives of the 

 group, and it had become clear that a revision and extension of' 

 our knowledge was needed. That work you have been carrying 

 out since 1910, in a manner that has evoked the admiration of your 

 fellow-workers for its care and accuracy in description and its. 

 insight into morphological conclusions. That you have enriched 

 systematic lists with many new species is of less importance than 

 the light which you have thrown on the relationships of the various 

 genera, both living and extinct. In awarding you the Proceeds of' 

 the Murchison Geological Fund, the Council recognizes, not only 

 the value of the work, but the enthusiasm that has led you to. 

 devote your leisure to its preparation and, in many cases, your- 

 means to its worthy illustration.
