15. From the result obtained in experiment 26, it appears 

 that in a 2 per cent phenol extract of lymph glands, 8 days old, 

 the virus of rinderpest is destroyed. 



16. From certain results mentioned in the discussion, it is ad- 

 visable to use a 0.75 per cent phenol extract not over 15 days old. 



17. From the results obtained in working with rinderpest, 

 it is very plausible that similar or even better results may be 

 obtained with the virus of hog cholera along these lines. 



18. The tissues best adapted for this work are the liver, spleen, 

 lymph glands, heart, fourth stomach, csecum, and colon.
