THE ALKALINE EOCKS OF SOUTH-WEST AFEICA. 

 Sir, — In the Geological Magazine for December, 1915, you 

 published a letter from me under the above title. In that letter 

 I expressed the intentiou of visiting the occurrences of alkaline 

 rocks [in the desert south of Luderitz Bay], and of describing the rocks 

 in detail. I was aware at the time that Professor Erich Kaiser, the 

 distinguished petrologist of Giessen, was in South- West Africa, but 

 I was not aware that he had come out from Europe for the express 

 purpose of studying these very rocks. I have now returned from 

 a visit to South- West Africa, where I had the pleasure of renewing 

 my acquaintance with Professor Kaiser, and I learned that he has 

 utilized his enforced leisure in the country (as a prisoner of war) by 

 studying these alkaline rocks most minutely and mapping the 

 occurrences on special, large scale topographic sheets prepared for 

 the requirements of the diamond-mining companies. Professor 

 Kaiser and Dr. Betz most kindly arranged an extensive tour for me, 

 when I was able to visit and collect material from all the principal 

 localities. Under the circumstances I must of course renounce my 

 intention of writing anything more about these rocks until Professor 

 Kaiser's memoir appears ; I can only assure you that that memoir, 

 when it does appear, will possess a quite extraordinary interest for 

 penologists.
