JET. 83.] GEOLOGICAL PUPILS. 391 



September 1892 Professor E. David wrote to his "dear 

 master " : " Allow me to take this opportunity of thank- 

 ing you again most sincerely, not only for the very 

 cordial assistance which you rendered me in securing 

 my present appointment, but also for your great kind- 

 ness to me at Oxford, and the interest in geology and 

 first grasp of its true principles which your lectures 

 and field excursions at Oxford afforded me. I hope 

 that my subsequent work will not discredit your early 

 teaching." 



Another student with whom he kept in touch was a 

 Balliol man, now Professor A. P. W. Thomas of Auck- 

 land University, New Zealand. Mr C. L. Barnes, 

 author of the * Rock History ' of the earth, was an 

 attached pupil, who wrote to him and not in vain 

 for advice and criticism. Another was the Rev. John 

 Hawwell of Ingleby Vicarage, Northallerton, whom he 

 encouraged to persevere in his work among the boulders 

 of Yorkshire. About a year ago the writer of this 

 memoir received a letter from Mr Hawwell, saying, 

 " The one [letter] written to me when T was in the 

 Radcliffe Infirmary, suffering from an attack of diph- 

 theria, to which I fell a victim while undergoing ex- 

 amination for the Burdett-Coutts Scholarship, particu- 

 larly illustrates the kindness of his disposition, of which 

 I have so vivid and reverent a recollection." Among 

 other old pupils may be mentioned Mr F. A. Bather, 

 of the Geological Department, British Museum, who is 

 distinguished for his researches on the fossil Crinoidea.
