Summary and Conclusions . — This brief note does not a 
bring forward any facts bitherto unknown, but attempts to 
compare and coordinate certain known facts with a view to 
demonstrate their essenlial similarity and homology. The 
conclusion reached is thaï the phrase « infective granule » is 
misieading and erroneous, since the bodies so termed are 
true endogenous chromidial buds. Consequently the terni 
« granule-formation » should be replaced by « endogenous 
bud-furmation » and the terni « granule shedding » by extru- 
sion of buds or some similar phrase.
