It is exceeding brittle and the pressure of a needle on the cover-slip can be seen under the microscope to be sufficient to crush it into amorphous frag- ments. It gives the reactions for calcium carbonate, effervescing violently on the addition of hydrochloric acid. The stem finally ends bluntly in a rounded tip. Along its whole length and forming a tuft at its extremity, are on every side the radiating, club like ends of the filaments. These are very long and slender and rather larger at their extre- mity than elsewhere. Sometimes they are branched. The outline is not always smooth — sometimes they are barbed along their whole length like a very slender pine cone or a head of wheat. This appearance, as is well known, is described by Boström1) as due to de- generative changes with the Splitting of the thickened capsule or the end of the filament but its constancy and elaborate development in another species of Actino- myces recently found in a spontaneous infection in a rabbit and soon to be de- scribed, leads us to think this explanation hardly adequate because the appearance is seen in preparations carefully.
