MEETING HELD ON MONDAY, 12th SEPTEMBER, 1960 
In the Chair: Prof SCHERMERHORN 
Introduction by the Chairman 
I am not very well prepared for this business

radial triangulation already in my country — 
and have done so for some time > and because 
it was Holland who proposed this as a subject 
for the Conference as one of the invited papers, 
Archives 5 
that I took the liberty of accepting the invita- 
tion of Professor Cassinis. ; 
First, may I ask Professor Roelofs to give his 
report about this, and to make some remarks 
about radial triangulation.
