    All bacteriologists are not quite as convinced as Koch as to the existence of spores. Muir* and Ritchie say that in such a minute organism it is extremely difficult to recognise the exact characters of the unstained points. Hence, as already stated, some observers believe these unstained: points to be Fig. 1.—Tubercle Bacilli and some Epithelial Cells in Sputum. x 1,000. Vacuoles appear in some of the bacilli. spores, while others consider them to be merely vacuoles. The balance of evidence, from analogy, and on biological grounds, appears to the writer to strongly favour the view that spores exist, although whether the unstained points observed by Koch were vacuoles or not future research must decide. Koch states that spore-bearing bacilli are often numerous in sputum, especially where caseous infiltration exists, * “ Manual of Bacteriology.”
