Quotation from: Manual of Surgery

Rigors may occur, but the temperature is not necessarily raised--indeed,
it is sometimes subnormal. The pulse is small, feeble, rapid, and
irregular. Unless amputation is promptly performed, death usually
follows within thirty-six or forty-eight hours. Even early operation
does not always avert the fatal issue, because the quantity of toxin
absorbed and its extreme virulence are often more than even a robust
subject can outlive.
