Fig. 2.—Early stage of cupule; p, p', as in Jig. i; w, probably a rim cell between two gemmiparous areas; a, apical cell; /, /, line showing tissues of thallus involved in a cupule. only a modified form of the chlorophyllose filaments of the air cham- ber. So natural and neat did the homology appear, that the brief prior statement of it by Campbell (I. c.) was discovered with a dis- tinct sense of disappointment when we began to look into the litera- ture. But evidence for this homology could not be found therein, and against it was to be put the fewness of the cupules, their limita- tion to the median line, where the air chambers are least developed, and the fact that the gemmiparous region covers many times the area of an air chamber. The matter evidently needed examination. Actual observation of the origin of the cupule speedily dissipated all.
