The cords used for treatment are removed from the bodies of the rabbits, by an aseptic method, and are cut into lengths and hung in glass jars, with some chloride of calcium in them, for drying. The jars are dated, and then kept in glass cases in a dark room at a constant temperature. To make sure that the cords are aseptic, a small portion of each cord is sown on nutrient jelly in a test-tube, and watched, to see that no bacteria occur in the tube. For each injection, a certain small quantity of cord is rubbed-up in sterilised fluid; and these subcutaneous injections give no pain or malaise worth considering. Of course, the treatment is adjusted to the gravity of the case. A bite through naked skin is more grave than a bite through clothing; and bites on the head or face, and wolf-bites, are worst of all. The number and character of the scars are also taken into account. An excellent description of the treatment, by a patient, was published in the _Birmingham Medical Review_ of January 1898. It gives the following tables of treatment:-- 1. _Ordinary Treatment._ Day of Days of Drying Treatment. of Cord. 1 14 and 13 2 12 and 11 3 10 and 9 4 8 and 7 5 6 6 6 7 5 8 4 9 (1/2 dose) 3 10 (full dose) 5 11 5 12 4 13 4 14 (1/2 dose) 3 15 (full dose) 3 2. _Cases of Moderate Gravity._ Same treatment, up to 13th day.
