What is the summary for Chapter 5 of Harry Potter and the Sorcerers Stone?

Hagrid goes
into the courtyard behind the Leaky Cauldron and taps a certain bricks in the courtyard wall.
Instantly the bricks shift and move to create an opening into a whole new city. This is Diagon
Alley, the place in London where wizards do their shopping. First, Hagrid and Harry must go to
Gringotts Wizarding Bank and withdraw money from the small fortune his parents left him.  Hagrid
also has to make a secret stop in the bank for Dumbledore. Gringotts is a very secure place,
managed little goblins who also use dragons to guard wizard fortunes stored in vaults. A goblin
named Griphook takes Harry and Hagrid on a crazy ride in a little cart along a track that is
part of a network that leads to the vaults. Hagrid gets very sick in the speedy ride. Once the
money has been obtained, Harry shops for his school supplies. He buys a robe, books and a
cauldron with wizard money --bronze Knuts, silver Sickles and golden Galleons. Hagrid buys him a
snowy owl named Hedwig for a birthday...
