135 The temperature limitations of life, and to some extent of growth, are summarised for a large number of species by Davenport, Exper. Morphology, cc. viii, xviii, and by Hans Przibram, Exp. Zoologie, IV, c. v.

342 The presence of this little liquid ãbourrelet,ã drawn from the material of which the partition-walls themselves are composed, is obviously tending to a reduction of the internal surface-area. And it may be that it is as well, or better, accounted for on this ground than on Plateauãs assumption that it represents a ãsurface of continuity.ã
343 A similar ãbourreletã is admirably seen at the line of junction between a floating bubble and the liquid on which it floats; in which case it constitutes a ãmasse annulaire,ã whose mathôÙeôÙmatôÙiôÙcal properties and relation to the form of the nearly hemispherical bubble, have been investigated by van der Mensbrugghe (cf. Plateau, op. cit., p. 386). The form of the superficial vacuoles in Actinophrys or Actinosphaerium involves an identical problem.
394 This, like many similar figures, is manifestly drawn under the influence of Sachsãs theoretical views, or assumptions, regarding orthogonal trajectories, coaxial circles, confocal ellipses, etc.
