SOUTH AFRICA MEDAL. XXIX 



resolved that this eleventh award of the South Africa medal and 

 grant, bestowed on the recipient for achievement and promise in 

 scientific research in South Africa, shall be made to Mr. Innes, 

 and in now handing him this mark of appreciation, I voice the 

 hope, which I am sure the whole Association shares with me, 

 that investigations of the important and valuable character of 

 those carried out by Mr. Inues in t!he past may yet long be con- 

 tinued by him.
