Minutes of Proceedings. ix 
The annual change in the horizontal intensity shows a decrease in 
absolute magnitude towards the north ; over the greater part of the Union 
it has a value of from 80 y to 100 y yearly and is a decrease. 
Oedinaey Monthly Meeting. 
June 17, 1914. 
The President, Dr. L. Peringuey, was in the Chair. 
The Minutes of the Meeting of May 20th were confirmed. 
James Hutcheon was nominated for membership. 
A. G. HowiTT, P. Battaerd, H. Pealing, and P. Lindsay Sandes were 
elected Members. 
Dr. W. A. Jolly gave an account of the electrical discharge of 
Narcine. 
Curves of the electrical discharge of a fish of the Torpedo family 
(species not yet determined) were exhibited. The curves were photo- 
graphically recorded by the string galvanometer. The direction of the 
current through the fish is from the ventral to the dorsal surface. The 
deflections which make up the shock occur with a rhythm of about 50 
per second. 
Mr. K. H. Barnard gave an exhibition of living Phreatoicus, 
Phreatoicus is a type of a very peculiar family of Isopods. Although 
in most respects an Isopod it has peculiar features which link it on to the 
Amphipods. So far the only members of this family have been found in 
Australia, New Zealand, and Tasmania. Last year, however, another 
species was discovered on Table Mountain. This is further evidence 
of a former land connection between the southern continents. It is 
thought by a study of the embryology some light may be thrown on 
the systematic position and the primitiveness of Phreatoicus. 
Note on Bushman Paintings from Southern Ehodesia." 
L. Peringuey exhibited tracings of Bushman Paintings from Southern 
Ehodesia which throw quite a different light on the technique and 
probably the mental evolution of the Bush people who executed the same. 
As usual, animals abound, but they are much more skilfully delineated 
than those from the Cape Colony, Orange Free State, Natal, etc. ; the 
graceful attitude and outline of some of them make those of the latter look 
commonplace. For instance, the spiral of the horns of the Koodoo is very 
plainly indicated, which is not the case in any of the numerous transfers 
from the Cape, etc., known to the Exhibitor. Then the representation of 
the human figure is of a much superior type, and seems to indicate a slight
