Valuable picture by ….. property of Lord … exhibited at the Exhibition of the old Masters 1871 – was full of cracks & the ground appeared as it if would chip off indeed, it had done so in one or more places To save it from further damage I would advise that a rim of wax be placed all round the picture which should be laid flat. Then pour over the picture a thin solution of good size or of isinglass into which had been put a certain quantity of a solution of gum Senegal with a very minute quantity of glycerine to prevent brittleness – the proportions to be determined by a few rials – leave sufficiently long on for the lipid to find its way under the cracks. Then raise the picture to a slight [melence] remove a portion of the wax rim and allow all superfluous liquid to run off – then let the picture dry – and apply carefully a warm iron to iron down the loose flakes of the ground using thin paper under the iron (probably tissue paper) – If the flakes of preparation are thus secured – all superfluous size may be carefully washed off from the surface . with a sponge and warm water not using too much water
