Further Magnetic Observations in South Africa. 
11 
The observations taken and the methods of taking them were the same 
as have aheady been described at considerable length in connection with 
previous magnetic work in South Africa.* The only change was in the 
astronomical observations for azimuth and longitude, where for each 
pointing on the sun both horizontal and vertical circles on the theodolite 
were read. The method is described fully by Bauer, f 
The values given for the magnetic elements are uncorrected for 
variation, either secular or diurnal.
