Sir William Logan 1798 - 1875

Sir William Logan I fancy I cut the nearest resemblance to a scare-crow. What with hair matted with spruce-gum, a beard three months old ... a pair of cracked spectacles ... [and] a waistcoat with patches on the left pocket where some sulfuric acid, which I carry in a small vial to try for the presence of lime in the rocks, had leaked through. - William E. Logan
