In the original contribution published under this title June 5 (200:820-823), two blood pressure readings for case 1 were in error. Thus, where p 820, right column, line 8 shows a pressure of "150/210 mm Hg" and line 22 shows "160/200 mm Hg," these should read as 150/20-0 and 160/20-0 mm Hg, respectively. Further, in case 1 and case 3, it was stated (p 820, paragraph 5, line 12; p 822, line 14) that these patients received procaine penicillin G intravenously. The correct drug is potassium penicillin G.
