Itwould be thought that all doubtabout the method of their formationwould be set at rest by ascertaining^^hethe^ the tubules were patent orotherwise—by immersion of cariousteeth in aniline dyes or carminesolutions. This apparently has beendone by the advocates of bothhypotheses, with the astonishingresult that both admit the possi-bility of the staining of the interiorsof the tubules in many instances. In the vanguard of the advancingmicrococci, the traversing of the inter-globularspaces by the tubules can sometimes be beauti-fully observed. At an early stace, individual.
