(a) Dilutions of a phage lysate (IO- 2 , 10-'*, 10-^) were spotted (10 pit) on a lawn of washed spores; + indi¬ 
cates turbid plaques as well as total lysis occur in the spotted zone, - indicates that individual plaques do 
not form although killing may occur. 
(b) Thorne and Merle reported that SP16 plated on B. licheniformis 9945A. (Microb. Gen. Bull. 43:7-10).
