This is a slightly manipulated image of the original (below) with an overlay of a daguerreotype process. The math notes (square roots of numbers from 25-60,025 in 25 increments) occurs on the back of several pages of foolscap note “di geologiska formationrma” and by the footnotes it seems as though the notes are from 1893/5 or thereabouts. In any event the calculations have a certain beauty to them.
