In the 1860s the first facsimile of Domesday Book was created by the process of photozincography (later termed zinco), and was executed under the directorship of Henry James at the Southampton offices of the Ordnance Survey.
[full citation needed] On 24 January 1861, Sir Henry was granted permission to photozincograph the Cornwall fragment of Domesday as a Treasury funded experiment to determine the success of the process.
Burtt’s description of the preparations extends to the actual photozincographic process, including James’s insistence that all plates should be developed and printed before the folios were returned.
Despite his claim that the public sale of the bound and engraved copies could cover the entire cost of the photozincography of the counties, the Lords of the Treasury wished to consult the Master of the Rolls regarding the comparison of James’s photozincographic reproductions with a rival process employed by Rev.
However, in order to secure this permission over Larking's process James had to provide the Treasury with evidence of public interest and a guarantee of low-cost production.
