106 PASTEUR AND AFTER PASTEUR 



death-rate, calculated on the admissions, was, not- 

 withstanding the exclusion of " bacteriological " 

 cases, the lowest on record viz., 7*7. It also gives 

 tables, pp. 253, 254, showing the contrast between 

 cases treated with antitoxin, and cases treated 

 without antitoxin. Of course, taking all forms of 

 diphtheria together, and thus including all the 

 trivial cases, which did not want the antitoxin and 

 therefore did not get it, the death-rate is lower 

 among the cases treated without antitoxin. Taking 

 the severe cases by themselves the laryngeal cases 

 and the tracheotomy cases the death-rate is far 

 higher among the cases treated without antitoxin. 

 Here are the tables :

 was an increased prevalence, that year, of diphtheria:
