purposes. If the serum in this dilution does not 

 act, the treatments are continued until such 

 power is gained. 



The efficacy of the serum treatment of 

 cerebrospinal meningitis has been proven by 

 the following facts gathered from statistics : 



1. Diminution of mortality. 



2. Influence on the symptoms in each partic- 



ular case. 



3. Reduction of the duration of the disease 



and the rarity of after-effects. 



DIMINUTION OF MORTALITY. 



Statistics give the mortality from cerebro- 

 spinal meningitis in different epidemics at from 

 30 to 80 per cent. . In infants 100 per cent. 



In 1909, during an epidemic in France the 

 mortality rate was remarkedly decreased by pjj,?,^"*^'^ 

 serUm therapy. 402 cases were reported, with 

 66 deaths; a mortality of 16.44 per cent. In 

 nineteen of these cases the patients were either 

 in extremis when the injections were given or 

 death was caused by some complication. Cases 

 treated during the same epidemic, without 

 serum, showed a mortality of 65 per cent. 



Reports show that the best results were 

 gained by early injections of the serum. 

 Mortality in cases treated before the third day 

 was less than one- third that of those where 

 treatment began after the first week.
