    that we can at a glance find the various articles on his subject should we wish to consult them in detail: for this alone we are deeply indebted to him, for all laboratory workers are keen to have a full list of references to articles on the problems upon which they are engaged. The subject of anserobic infections of animals is one brimful of points for discussion: I should like to limit my remarks to three items, all referred to in this paper. They are :— (1) Organisms associated with Black quarter and immunisation against them. (2) The association of B. welchii with animal diseases, with special reference to lamb dysentery. (3) Some general debatable points. Organisms associated with Blackquarter, and Immunisa¬ tion against them. That Blackquarter is the result of the action of more than one organism is becoming more apparent as time progresses and as the results of various bits of research come to light. Undoubtedly the similarity between B. chauvoei and the Vibrion septique has led to much confusion in the identity of the organism found in the muscle lesion, but now that we have a clear conception of the differences between the two, and now that we understand what a pure culture of an anserobe really is, it becomes more and more apparent that Vibrion septique has been labelled B. chauvoei on many occasions or that so-called pure cultures of B. chauvoei were really mixtures of that organism and others. It has been our privilege to examine some strains of so-called B. chauvoei isolated from Bauschbrand (Blackquarter) cases by Continental workers and from which agents used in the immunisation against that disease have been made and used. Of eighteen such cultures examined, only two have been identified as B. chauvoei : fifteen were pure cultures of Vibrion septique and one was a pure culture of B. histolyticus. It will thus be evident that, on the Continent, at least, organisms other than B. chauvoei, notably the Vibrion septique, are found in pure culture in association with Blackquarter lesions. From American laboratories we have received three cultures of B. chauvoei, all of which we have been able to confirm as pure cultures of that organism.
