I have found an ancestor on the recently digitised National Archives BT 159 series - Registers of Death at Sea of British Nationals, 1875-1891.
The image that I have been able to download contains the person's name, the name of the ship, age and 'page'.
Presumably being a register, the 'page' refers to some other document, but I could not find anything about what this could be on either the NA or the BMD Registers websites.
Does anyone know what this refers to and if indeed still exists?
