In all cases the radial ribs areseen in the negatives of the photographs to be very pronounced. Even at so early astage as fig. 1 the fluting is well developed. The two photographs taken of stage 3had each of them an isolated jet, probably owing to the fact that when working withso sticky a liquid it was diflScult to avoid contaminating the cloth on which the spherewas each time re-polished after washing in water, with the result that the spherebehaved as if locally rough.

The relatively great length of this jet brings out verywell the part played by the viscous drag in hindering the flow of that portion of theliquid sheath which has remained in contact with the sphere. In the last figureNo. 4, of this series the droplets just visible in the centre, below the level of thegeneral surface, correspond to those of figs. 6 and 7 of Series XIII. at a much higher .tU Kj j^ m MESSRS.
