While accepting that the phagocytes do truly absorb the micro-organisms, other opponents of the theory have urged that these cells are only capable of including micro-organisms already killed by other means, and that living microbes are solely to be found within the cells in those cases where there has been a fatal ending—in tuberculosis, mouse septicaemia, and so on. Against this may be brought the fact determined by Lubarsch, that the phagocytes of several animals, refractory to anthrax, take up living bacilli that have been injected with greater eagerness than they include those which have been killed before injection. But, further, this objection may be- disposed of by direct observation of bacteria undergoing devel- opment from within the interior of phagocytes after the latter have been destroyed by a substance which is at the same time a favorable medium for bacterial growth, as, for instance, beef broth. Such observations have been made upon pigeons, ren- dered immune to Please note that these images are extracted from scanned page images that may have been digitally enhanced for readabil
