    possessed, of preserving tlie lymph fluid, and, as was understood, active. III. The third and last form of tube is that of which I have already briefly detailed the origin, and I now resume the description of it. It is, as I said, a simple straight tube, cylindrical, open at both ends, and of such dimensions as to fulfil the follow¬ ing conditions, upon which its peculiar value as a means of preserving lymph for future everyday use essentially depends. It must be— 1. In the first place, of such tenuity that it can be sealed instantaneously at the flame of a candle. 2. In the second place, it must be large enough to con¬ tain as much lymph as is sufficient for one vaccination. 3. In the third place, long enough to admit of both ends being sealed hermetically, without subjecting the charge to the heat of the flame. 4. And, in the fourth place, strong enough not to break easily in the mere handling. There need be no difficulty in procuring tubes which perfectly answer this description ; only they must be made according to a certain standard, which obviously, from the very nature of the case, is not an arbitrary one, admitting of being altered to suit the notions of different individuals, but one concerning which, within certain limits, there can be no dispute nor difference of opinion.* * This standard is not adhered to, as it ought to be, by the instrument-makers, chiefly owing to the conflicting orders given them by different persons ; and hence, large quantities of tubes are in circulation, which, being much too large to be manageable, give a quite erroneous idea of the method.
