law: Sale of Goods Act, 1930
  34. Effect of part delivery
  A delivery of part of goods, in progress of the delivery of the
  
  whole has the same effect, for the purpose of passing the property in such
  
  goods, as a delivery of the whole; but a delivery of part of the goods, with an
  
  intention of severing it from the whole, does not operate as a delivery of the
  
  remainder.
