Cuutrols. A control series Avas started, using normal horse serum. 

 Of the 7 cases so treated 4 died — a mortality of 57 per cent. One 

 case was distinctly harmed by serum, 2 probably were harmed 

 and one ^vas distinctly benefited. That the work Avould be more 

 valuable ^vith controls is luiquestioned. The high mortality in 

 the normal horse serinn controls ruled out this procedure. The 

 difficidty of finding sufficient acceptable cases Avould have iniduly 

 prolonged the work. The records of Charity Hospital, Ne^v Or- 

 leans, for a three year period, including the year of our work 

 there, w^ere collected and analyzed as a rough control. There w^ere 

 258 cases with 56 deaths — a mortality of just over 22 per cent. 

 Forty per cent had a temperattnx dmation of less than thirty 

 days. The average duration of temperatme ^vas thirty-eight days 

 for this grouj). In the treated cases the mortality ^vas 8.9 per cent; 

 35 per cent had a dmation of less than thirty davs. and the a\er- 

 age duration was thirty-eight days.
