In the second phase of the life history of the organism many degreesof transition may be observed. These are represented uby chains, bun-dles, and masses of intertwined filaments, isolated filaments, large dumb-bell bacteria of the type p, p, and_p, Plate V., and masses of diplococci;the large dumb-bell bacteria being derived from the diplococci, the twooriginal cocci linking together. The chains are often surrounded bymasses of diplococci, while in the same chain small diplococci may alter-. PLATE VI.
