Sizar (Cambridge).  Formerly students who came to the
  University for purposes of study and emolument. 
  But at present they are just as gay and dissipated as their
  fellow collegians.  About fifty years ago they were on a
  footing with the servitors at Oxford, but by the exertions
  of the present Bishop of Llandaff, who was himself a
  sizar, they were absolved from all marks of inferiority
  or of degradation.  The chief difference at present between
  them and the pensioners, consists in the less
  amount of their college fees.  The saving thus made induces
  many extravagant fellows to become sizars, that
  they may have more money to lavish on their dogs,
  pieces, &c.
