I am reading minutes relating to the administration the the Old Age Pension. National Records of Scotland reference GRO5/779.
Under the subject of the Census being returned to Scotland The Registrar General said (as recorded in the minutes) in November 1909:
"Transmits files as to this matter is strongly of the opinion that a case has been established for access being given to the Census Returns and further thinks that Scottish Census Returns for 1841 & 1851 now crumbling to pieces in London, should be transferred to Scotland & housed in the Register House as soon as possible."
