     Karl Pearson organized the collection of data on over 1100
     families in England in the period 1893 to 1898. This particular
     data set gives the heights in inches of mothers and their
     daughters, with up to two daughters per mother.  All daughters are
     at least age 18, and all mothers are younger than 65.  Data were
     given in the source as a frequency table to the nearest inch.
     Rounding error has been added to remove discreteness from graph.
