    that if the lymph do not exude freely the tube may require to be drawn several times more or less obliquely across the surface of the vesicle, or cluster of vesicles, until a sufficient charge has entered; but generally if the exudation be co¬ pious, and a drop of some size have formed before you begin to take your supply, the orifice of the tube need not, indeed ought not, to touch the surface, but is merely to be clipped into the clear fluid; and one may commonly in this manner, from one infant’s arm, charge five or six tubes in almost as many seconds, with perfectly pure and limpid lymph, which shall contain neither epithelial scales, nor pus globules, nor blood discs, and is therefore, so far, in the best possible condition for preservation. In order to obtain the lymph from a tube for the purpose of vaccinating, the sealed ends are broken off, and the fluid contents blown out gently on the point of the lancet or vaccinator. This description may appear to some to be unnecessarily tedious and minute. But I have endeavoured to be as con¬ cise as I could, consistently with perspicuity, and with the importance of the subject. The difficulty, however, is to convey by description an adequate idea of the facility and expedition with which these manipulations are performed. Your fingers even require training before becoming suffi ciently alert to take advantage of the instantaneousness with which the law of capillarity charges the tube for you, and with which the heat of the weakest flame seals it. No one who procures proper tubes, and gives them a fair trial, according to the foregoing directions, can fail to perceive that they furnish, beyond comparison, the easiest and most expeditious means of taking charges of lymph, for B
