With regaM to the morphology of the tubercle fungus he mentioned that he had never failed to detect genuinely ramified forms in sputum whenever he had leisure to seek them out. The type of ramification was that of the genus Cladothrix, and from the researches of Fischel, Coppin ;[ones, lCiayo Bruns, and

He gave reasons for refusing to admit the spore-nature of the unstained bodies so often found embedded in the rods, and pointed out the hygienic importance of that fact. He emphasised the value of the staining reaction, long considered to be peculiar to the tubercle and leprosy bacilli, but now known to be shared by a smegma bacillus, and by the pseudo-tubercle bacilli isolated by Moeller and others from cow-dung--by Moeller, from %he leaves of Timothy grass near the G6rbersdoff Sanatorium, and by Rabinowitsch, from butter. Cultures of the three last-named organisms were demonstrated as well as slides showing their remarkable resemblance to the genuine %uberole organism.: The cause of the staining reaction was the presence in the sheath of the bacillus of a peculiar wax, as was shown last year by Arensen. This underwent gradual extraction by alcohol and ether, with the
