In December 1851, Arthur Malet, Chief Secretary to the Government of Bombay, sent out a circular memo to officials across British India, containing instructions on how to counter the threat posed by white ants, better known to us as termites, to paper records. Paper and wood are particularly appealing for termites because they contain cellulose, which is a rich source of energy for the insects. In his circular memorandum, Malet advised on how best to discourage termites taking refuge in and eating their way through India Office The department of the British Government to which the Government of India reported between 1858 and 1947.

Malet’s Conservation Manual
‘First,’ began Malet, ‘boxes should be repeatedly well sponged for several days, both outside and inside, with a strong solution of sulphate of copper […] in water. They should also be lined with common brown paper first saturated in the same solution and dried in the shade, and a similar solution should be used, instead of simple water, in making the paste required in lining the boxes.’
‘Second,’ continued Malet, ‘should it be practicable to steep the planks before they are made up or the boxes in a tank of the solution it will be more efficacious, and soft wood such as deal or cotton tree might be used and in this case paper lining in the boxes would be unnecessary, a great advantage as it has a tendency to increase the moths and cockroaches which are very destructive to paper.’
‘Third, the supports of boxes […] should rest in, or rise from stone or hard earthenware veneers, containing a similar weaker solution of blue stone [copper sulphate], a very small quantity of oil being added, to form a pellicle [or coating] which will help to prevent evaporation – when this is not procurable a stone support surrounded by heaped up sand might be used, a large plate of zinc or any cheap metal between the posts and the floor is efficacious, and boxes of records in a travelling camp may be placed on inverted bottles buried to the shoulder in the floor.’
‘Fourth,’ Malet went on, ‘it is suggested that all Duftur Roomals [large squares of cloth] should in the first place be soaked in the solution or one of Ruskapoor [a mercury sulphate solution] or corrosive sublimate, and then simply dried, before being appropriated to keep papers in – but it is not considered certain that the cloth would not be injuriously affected by it.’
The hazardous nature of the measures proposed was not lost on Malet: ‘It is suggested that great precautions be taken to prevent accidents from the use of the poisonous wash above recommended during its preparation, though it is stated to be less dangerous than others when once in use as it does not give out noxious fumes in the same manner as some preparations of arsenic and mercury.’
