xlii PKOCEEDI>*G-S OF THE GEOLOGICAL SOCIETY. [vol. ixxvi, 



In collaboration with Dr. Gertrude L. Elles and Prof. C. Lap- 

 worth, you have produced a Monograph of British Graptolites 

 which is, and will remain, of the utmost service to all students of 

 the Palaeozoic rocks. Your special knowledge has also been most 

 usefully applied to the examination of fossils of this class obtained 

 from distant countries. 



Fortified with your pakeontological knowledge, your field- work 

 on the Silurian rocks of the Welsh borderland, on ground so 

 familiar to the Pounder of this Medal, has taught us much regard- 

 ing the sequence and correlation of this difficult system. Your 

 results in this field, taken in combination with those of Prof. Lap- 

 worth and Dr. Elles in other parts of the sequence, have provided 

 us with a record of the Graptolite succession of Silurian times 

 which has become the standard of reference wherever the rocks of 

 this age are studied. It has been the privilege of the Society to 

 publish most of the papers in which these far-reaching stratigra- 

 phical researches are embodied, and your own individual contribu- 

 tions, on the Lower Ludlow formation, in 1900, and on the 

 Tarannon Series, in 1906, are essential links of the chain. 



We recognize that the strenuous service which you have been 

 doing for the State during and since the War must take precedence ; 

 but may we hope that you will, when possible, resume the studies 

 which have proved so profitable to us ? 



In handing you this Medal and Award on behalf of the Council, 

 I ask you to accept also my personal congratulation on your success 

 in advancing geological science. 



Mrs. Siiakespeab replied in the following words : — 



Mr. PRESIDENT, — 



I thank you, Sir, and the Council of the Geological Society for 

 the honour that you have done me in the award of the Murchison 

 Medal — an honour which I value most highly. I only wish that 

 I had done more to deserve a distinction so entirely unexpected ; 

 but I must confess that during the past five 3 r ears my energies 

 have been diverted from the stud} 1- of Palaeozoic geological strata 

 and extinct fossils to the no less complex problem of the obscure 

 workings of Government Departments and modern humanity. 



My friend and fellow- worker, Dr. Gertrude Elles, on a similar 

 occasion last year, paid me a generous tribute which I warmly 

 reciprocate.
