pigs, using 6 hour, 30 cc, virulent saline solution, together with virus 

 blood and all have produced very potent sera. 



Thus, these results look suggestive of a considerable saving in the 

 cost of manufacturing serum. 



OTHER WORK. 



In addition to the work with salt solution, I hyperimmunized eight 

 pigs with extract from virus pigs. Six of these animals died from septic 

 infection and two produced potent sera. It seems feasible that the ex- 

 tract from virus pigs may prove efficient as a virus for hyperimmunizing 

 where proper caution is taken in securing and using it.
