The introduction of antitoxic serum has modified materially theprognosis of diphtheria. The value of the remedy may be judgedeither by individual clinical experience, or by the statistical latter presents great difficulties in arriving at an absolutely trust- jworthy conclusion, because diphtheria varies greatly in the severity Iof the toxaemia which it produces, in the danger connected with itslocal manifestations, and in the character of the epidemic.
