De Bary -^ says that different portions of the same filamentmay alternately assume blue and yellow colour with iodine. The lengthalso of the members (cells) is unequal in some cases, not exceeding thetransverse diameter, in others several times greater. By aid of cultiva-tion, we are informed,^ Rasmussen^^ has distinguished three Fio. 2. Bacillus regret that I have discovered no picture of the organism found mpharyngeal mycosis. I feel quite confident that in my case the bacillusis not leptothrix buccalis, for reasons to be stated. Newcomb says ?°: These link-like processes vary in length, and in some cases curl up at their ends into fine hair-like filaments. Besides these spores there are
