 * Eliza's Surname
 * Readers will remember the old puzzle of the "Dutchmen's Wives," nearly two hundred years old.
 * Here is a new extension of it (sent by C. C. P. S.):


 * Smith, Brown and Robinson have provided themselves with a penny pencil each,
 * and took their wives to a stockbroker's office to buy shares.
 * Mary bought $50$ more shares than Brown,
 * and Robinson $120$ more than Jane.
 * Each man paid as many shillings per share as he bought shares,
 * and each wife as many pence per share as she bought shares,
 * and every man spend one guinea more than his wife.
