![The 5tli and 6tli days are the best for taking lymph, which may be done upon points or glasses, or in tubes; the points give the best results. They are charged on the 5th day, and re-charged on the 6th. This double charge is usually unnecessary ; but it is an additional security for success when they are used by gentlemen accustomed only to the use of tubes. These points may be safely kept three weeks, though the result is scarcely so brilliant as when they are used earlier ; in applying them, they should be slightly moistened with water, and well rubbed over a cluster of small scratches effected with a common sewing needle or sharp vaccinating Tancet. The lymph in tubes gives a good result if used ]proiliptly. These are filled direct from the pock, the 1 matter is then quickly blown out again upon a clean watch-glass, and an infinitesimal portion of perfectly ipure glycerine is well mixed up in it by means of a glass irod ; the tubes are then re-filled. This process is mecessary, or otherwise the lymph would coagulate in the itubes and refuse again to leave them. It is well not to itake more than two or three tubes from each pock; it is tthe lymph which first exudes which contains the true ^germinal material. Dr. Seaton thinks that one reason of the comparative iinstability of heifer lymph, particularly that in tubes, is tthe employment of pressure necessitated by the early](https://iiif.wellcomecollection.org/image/b22274054_0029.jp2/full/800%2C/0/default.jpg)
