Obituary. — We record 

 with grreat regret the 

 death of Mr. E. H. Lock, 

 F.R.H.S., which took place 

 on July 9, 1921. Mr. Lock 

 was 61 years of age. He 

 had taken an active part 

 ill the work of the Field 

 Naturalists' section for 

 many years. He held the 

 position of secretary for 

 seven years, from 1905 to 

 1912, and was Chainuan 

 from 1912 to 1914. He was 

 a member of committee 

 right to the last, and took 

 his part in our programme 

 of lectures and excursions. 

 During his last illness, Mr. 

 Lock received evidence of 

 the high regard in which 

 he was held by fellow- 

 members, both in official 

 letters of goodwill and in numerous visits. We are indebted to 

 the ''Register" for the loan of the excellent photograph of our 

 late membo:- which accompanies this note. 



An additional loss has been sustained by the club in the 

 death of Mr. Alexander M. Drummond, wdiich took place on 

 August 3. Mr. Drummond has been one of our auditors for 

 many years, and although his health w^as for many months past 

 far from good, he was present at several of our recent excur- 

 sions. Our sympathy is extended to Mr. E. Drummond in his 

 bereavement.
