THE SIMULTANEOUS METHOD 1 49 



It must be admitted, however, that Pasteur's method has done 

 much good and helped to rob anthrax of much of its former 

 terror, especially for the farmers of Europe. In America the 

 spread of anthrax has been checked in many districts by its 

 use. Dalrymple has pointed out its success in the lower Miss- 

 issippi valle3^ Xotwithstanding, it is highly probable that 

 the spreading of a knowledge of the specific cause of this 

 disease with that of the proper disposition of dead animals has 

 also exerted much influence for good in checking its ravages. 

 In Germany and England the stamping-out system is con- 

 sidered superior to vaccination. According to Crookshank, 

 in England it is regarded as the only reliable means of sup- 

 pressing the disease. To this end rigid laws have been enac- 

 ted. In this country as rigid measures as possible for its 

 eradication seem infinitely better than the general adoption of 

 methods for establishing a tolerance for its existence. 



§ 126. The simultaneous method. This method 

 which consists in the injection of anthrax antitoxin or serum 

 together with a small quantity of virulent anthrax bacteria, 

 has proven to be ver^- satisfactory. It has the advantage of 

 being administered at one time. This method of protection 

 against anthrax seems to have been first proposed by Sobern- 

 heim in 1899. Since that time Sclavo in Italy and others 

 have published on the method. Sobernheim reports excellent 

 results by the use of this method in immunizing cattle against 

 anthrax in South America. The serum is now produced in 

 large quantities in Germany. In this country, it is just begin- 

 ning to receive attention. 



§ 127. Prevention. In all cases the well animals should 

 be removed from the barns or yards containing the sick ones 

 and from pasture lands on which the sick became infected. 

 The\emperature of healthy and uninfected animals should be 

 taken morning and evening for from one to two weeks after 

 they are removed and all of those showing an elevation- of 

 temperature should be isolated. By careful isolation and safe 

 disposition of the dead animals the spread of the disease can be
