Summary. The need for, and difficulties commonly experienced during, the analysis of patterns of vectors with superimposed ‘noise’ upon the surfaces of spheres is discussed. A simple procedure is described whereby many of these difficulties may be circumvented and certain classes of systematic array detected even against a considerable random background. An extension of the same procedure to the analysis of vector patterns in a plane is discussed.
