Bacteria in the cavity more abundant and with denser stain than is here shown. Plant No. 57 inoculated with Bacterium solanaccarum August 17, 1896; collected and fixed in strong alcohol September 23. Drawn with the Abbe camera from a section cut on the microtome and stained with carbol-fuchsin. Slide i2o(*. Crystal-sand not present. (For a longitudinal section see fig. 94.).
