“…Although so high a case death rate has been uncommon, similar observations have been recorded in many quarters. This has been so in a quite special degree in Germany where it is emphasized amongst others by K6nigsberger (94), Wolter (198), Gundel (64), Paschlau and Sudhues (134), Degkwitz (36), and Woldrich (197).
