Bacilli increase in length, and, becoming more or less jointed as vegetative division takes place, form the long delicate jointed threads which are spoken of as Lepto- thrix forms when there is no apparent branching, but if pseudo-ramifications, such as are found in Cladothrix dicho- toma and are due to vertical division taking place in one of the terminal cells, are present, we have the Cladothrix Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Woodhead, German Sims, Sir, 1855-1921.
