     The data record the locations of the centres of 42 biological
     cells observed under optical microscopy in a histological section.
      The microscope field-of-view has been rescaled to the unit
     square.

     The data were recorded by F.H.C. Crick and B.D. Ripley, and
     analysed in Ripley (1977, 1981) and Diggle (1983). They are often
     used as a canonical example of an `ordered' point pattern.
