Constant observation was maintainedduring this hour, and the bacilli were seen gradually to dissolvein the vacuoles in which they lay, until at length all trace ofthem had disappeared, together with their containing vacuoles,and only the contracting vacuole remained in the homogeneousgranular substance of the swarm-cell. At the commencement of the observation this granularprotoplasm was much more turbid than at the close, when itwas remarkably hyaline; the swarm-cell appeared also to haveincreased in size, though it was difficult to determine bymeasurement in consequence of its changing form, No re-jection of refuse matter took place while the observation lasted. In the same preparation I watched a swarm-cell creepingin a straight line, with the strange snail-like movement sodifficult to understand. In its course it came to a small groupof motionless bacilli lying against the glass; immediately itchanged its linear form and spread itself out, covering four of. SLIME FUNGI—MYXOMVCETES 309 the bacilli. In about two minutes it resumed its former shapeand movement, and crept away, carrying off two of the bacilliin vacuoles. These observations seem to confirm the opinion of De Barythat the organisms under consideration should be classedamong the animal rather than the vegetable kingdom. Whena creeping swarm-cell is watched, with the projecting ciliumplaced immediately in advance of the nucleus, which nevershifts its position, and when we note the manner in which thevibrating extremity of the cilium appeared to detect thepresence of the bacilli, before the swarm-cell spread itself overthem; again, when we observe thecreeping action suddenly change,and raising itself from the decum-bent attitude, with a few lashingstrokes of the cilium the swarm-cellreleases its foothold and swims Fig. 140.—Cluster of TubuUnaaway; and when to
