Nuclei were not at first observed in the plasmodia. Cienkowski even stated expressly that the nuclei present in the swarm-cells disappear when they coalesce. But Schmitz' and Strasburger^ have recently established the presence of numerous nuclei in the plasmodium, and it may be presumed that they are the persistent nuclei of the swarm-cells and products of their division. Besides the proper constituents of the plasmodium strange bodies of very various kinds are often found inside it, such as spores of Fungi and Myxomycetes (see Fig. 183^ 12), parts of plants, &c. These objects are taken up from without into the interior of the growing and moving plasmodium, one may say engulfed by it, in a way which will be noticed again below, and they may be provisionally termed the solid Fig. 184.

Reinke has recently published an elaborate investigation of the various substances which enter into the composition of the plasmodium of Fuligo", to which the reader is here referred. The amoeboid movements of the swarm-cells are continued in the plasmodia. They may be seen in larger specimens by continuous observation even with the naked ' Sitzgsber. d. Niederrhein.
