(From Sachs, after Cienkowski.) acquiring a cilium at the end of a finely pointed process. Its movements are of two kinds-: a hopping movement, during which it commonly rotates round its longi- tudinal axis, while the outUne undulates ; and a creeping movement, which takes place on a firm substratum with the cilium in advance. The creeping is also some- times accomplished by the protrusion and re- traction of pseudocodes. The same swarm-spore often moves both by hopping and by creeping alternately. After passing through this stage, during which swarm-spores mul- tiply by simple division into two (such division takingplace in some cases even before leaving the spore), the formation of plasmodes begins. The swarm-spores taking part in this process are such as have withdrawn their cilia and exhibit creeping amoeboid movements. Several come into con- tact and coalesce, thus forming the beginning of the plasmode. Others are drawn towards itâhow, no one has ever found outâand successively coalesce with it, until a ' Fig. 333.âDidymiiim serpula Fr. A and B, plasmodes {natural ^ . â ' °. ^ size).
