DIPHTHERIA 



During the serum-period, the mortality of these 

 cases was 12.0. At the Trousseau Hospital, 

 without the serum, the mortality of these cases 

 during the same period was 32.0. 



Mortality among Cases requiring Tracheotomy. 



During the serum-period, the mortality of these 

 cases was 49.0. At the Trousseau Hospital, with- 

 out the serum, the mortality of these cases during 

 the same period was 86.0. 



Setting aside, out of the 448 children, those 

 cases of " membranous sore throat" or " pseudo- 

 diphtheria," in which the Klebs-Loeffler bacillus 

 was not found, there remain 320 cases where it was 

 found. Of these 320 children, 20 were just dying 

 on admission, and did not receive the serum. 

 Of the 300 who received it, 78 died =26.0. Before 

 the serum-period, the mortality of these cases at 

 the same hospital was about 50.0. The complica- 

 tions of diphtheria, such as paralysis, were much 

 less frequent during the serum-period than they 

 had been before it.
