Serum Treatment of Diphtheria in Cracow. — Dr. Stapa 

 has presented to the Cracow Medical Society a report of 

 the results obtained by the serum treatment of diphtheria 

 in the Children's Hospital of that city. During- the year 

 1895 the number of children subjected to it was 258. Of 

 these the mortality was 22 per cent. This compares very 

 favorably with the mortality in the ten previous years, 

 which was as hig-h as 56.3 per cent., there being- 709 deaths 

 out of a total of 1,354 patients who were treated by other 

 methods. Laryngeal croup occurred in 160 cases, and a 

 rash having- the appearance of scarlet fever and lasting- 

 from two to sixteen days in fifty-eig-ht cases. It was noticed 

 that certain samples alwa3's produced rash. No effect on 

 the occurrence of albuminaria by the serum could be 

 shown. — Medical Journal.
