Looking for an account of the voyage of the Panama from London to Melbourne in 1852, I consulted the three volume work Log of Logs by Ian Nicholson. These volumes list the whereabouts of known accounts of ships voyages - logs, diaries, newspaper accounts.
In Volume 2 there is a reference to a voyage by:
Panama
1852 clipper ship, Captain Lane, London 30.6 to Melbourne 12.11.52; +extracts from Edward Mallandaine's diary, *RHSV MS00065.
As a member I can consult that record for free.
