Minutes of Proceedings. xi 



themum was brought last year from the neighbourhood of KHpplaats 

 by Mr. E. Pillans. It somewhat resembles M. Bolusii, one of the 

 most curiously shaped plants of the Karroo. The name chosen for 

 it indicates its striking resemblance to its surroundings, for the 

 specimens which came fresh from the Karroo had the colour and 

 appearance of some coarse ironstone. 



In connection with the magnetic survey of South Africa, Dr. J. C. 

 Beattie gave an account of the methods employed in applying the 

 secular and the daily variations of the magnetic elements and their 

 reduction to a common epoch, July 1, 1903. 



It was further explained how the near value of the field was 

 obtained for each station and the disturbing forces thereafter 

 calculated. 



A number of maps were then shown embodying the results of the 

 consideration of this residual field. 



Ordinary Monthly Meeting. 

 Wednesday, May 29, 1907. 

 Mr. S. S. Hough, F.E.S., in the Chair. 



Mr. J. S. Henkel was nominated as an Ordinary Member by Dr. 

 L. P^ringuey and Dr. J. C. Beattie. 



Eev. J. H. Whaits was duly elected Ordinary Member. 



Professor H. H. W. Pearson gave some remarks on Welwitschia 

 mirabilis, and exhibited specimens of the plant. He dilated on its 

 many features of scientific interest. 



Dr. L. Peringuey communicated the results of an examination of 

 the Bushmen Crania in the South African Museum by Dr. F. 

 Shrubsall, from which it appears that the Strand Loopers are more 

 orthognathous than the Bushmen or Hottentots. The Strand 

 Loopers appear in all respects to be a purer group than the Bush- 

 men, and to be distinct from the Hottentots. The Hottentots 

 present dimensions exactly intermediate between the preceding and 

 the Bantu. In many characters they approach the negroes of 

 British Central Africa more closely than the Kaffir tribes of the 

 East Coast. 



Annual Meeting of the Society. 



Wednesday, July 31, 1907. 



Dr. J. C. Beattie, President, in the Chair. 



Dr. L. Peringuey, Hon. Secretary, read his Eeport, and that of 

 the Treasurer. Both Eeports were approved.
