Sc' i860, vol. viii. p. 227, the production of somewhat similar tubes from a portion of a large Desmid, through which ciliated zoospores are subsequently dis- charged. These appear to be produced by a breaking up of the endo- chrome of the frustule itself, near the part whence the tube issues. When discharged the zoospores were found to be -geVo" ^^ diameter, and provided with a single cilium. They, in fact, very closely resembled the bodies whose production Mr. Carter had vvatched within the so-called.
