A stoop-gallant is what?

Medical historians have never known what caused the sweating sickness. That the disease was neither plague nor typhus was clear from contemporary accounts. Its victims bore neither the boils typical of plague nor the rash of typhus. Now physicians Vanya Gant and Guy Thwaites, both of St. Thomas' Hospital in London, think they may have identified the killer. Sudor Anglicus, they say, may have been an early version of a disease that has made headlines in recent years: hantavirus pulmonary syndrome, which erupted in the Four Corners region of the American Southwest in the summer of 1993.
