He and most other Fellows of the Royal Society recognized syphilis and leprosy as distinct diseases, spread in different ways. But most other persons had conflated the two diseases in their minds, and so recoiled from syphilitics in much the same way as they would from lepers. This explained everything about how Saturn was reacting now. Daniel, F.R.S. though he was, reverted to superstition in the clutch, and allowed the gager the widest possible berth as he half-crawled and half-staggered toward the hearth. Some of his limbs dragged senseless on the floor, while others moved in spasms, as if he were being stung by invisible hornets. Trailing his nest of filthy blankets behind him, he slouched on the hearth, completely eclipsing the light of the fire, and hunched even closer to it, rubbing his paralyzed hand with his twitchy one. His gray hair would be dangling and burning in the coals now if he, or someone, hadn’t wrapped it all up in a sort of bandage-turban atop his head.
