Abstract while studying the mode of encysting shown by large forms of the unicellular animal of the genus stentor (500 - 1000 microns) we were able to consistently demonstrate the appearance of dwarf forms, not previously described, which arose from nuclei released from the disrupted larger cells. These larger cells had encysted in an unfavorable environment due to evaporation to a dry state.
