    one after another, giving at first a sudden start or jerk, and enlarging to twice their former dimensions before bursting open and spreading out ; discharg¬ ing from twelve to fifteen bright granules, and many molecules, which slowly disappeared. (Plate 2, fig. 17, 19, and 20.) Cancer of the Breast extending to the Axilla.— The whole arm, on the affected side, had been oedematous for two months, occasionally becoming very red and painful, and the skin had been punc¬ tured several times to relieve the swelling. Prom one of these punctures, at the back of the hand, a clear transparent fluid had been discharging in considerable quantities for some time, and I frequently collected and examined the fluid by the microscope. On every occasion, corpuscles, resem¬ bling in every particular the colourless corpuscles of the blood, were seen in it, accompanied with a fibrinous network. When the arm had been for a few days cool and free from pain, the fluid ne peuvent demeurer en contact sans se meler.”—Journal Universel des Sciences, 1 ere, sec. No 447. Of the same nature is the following:—We may often remark in the vicinity of falling water, and even in liquids while filtering, that spherules of the liquid run along the surface, and remain a consider¬ able time in a state of isolation without mixing; in these instances there can be no doubt that the spherule is covered with a film of air which it carries with it in its movements, and which prevents it mingling with the mass from which it has thus become temporarily separated. The central portion of the corpuscles, spoken of in the text, was alive, and by virtue of this vitality it exercised certain movements, by which a division into parts ensued; and the divisions or granules were wetted with the fluid of the outer part of the cor¬ puscle, which prevented them for a little while from coalescing, and so on; so that the phenomena observed were due to the alternate actions of an inherent vitality, and a general physical law.
