An Investigation into the Land and Sea Breezes Conditions at Port 
Elizabeth," by A. G. Howard, M.S. A. This is a second contribution to 
the Meteorology of South Africa. 
A paper was read by Mr. E. T. Littlewood, M.A., B.Sc, on 
Graphical Representation of Some of the Simpler Analytic Functions of 
a Complex Variable," illustrated by models and diagrams. The modulus 
of the function corresponding to each point of the (horizontal) xy plane 
was represented by the length of a vertical line erected at that point, the 
upper extremities of these lines forming a ('* modular ") surface, while the 
argument was represented by a family of curves (" stream lines ") drawn 
in the xy plane. Certain general results were established and methods 
given. 
In the models, the surface was suggested by a wire frame-work, which 
usually illustrated contour lines and vertical sections, while the stream 
lines, drawn on the horizontal base of the model, were visible through the 
framework. The simpler algebraic, circular, exponential and logarithmic 
functions were thus treated.
