The general reaction consists of an attack of fever, which, beginning mostly with chills, raises the temperature to over 39 deg., often up to 40 deg. and even 41 deg. Other noticeable symptoms are pains in the joints, a tendency to cough, great languor, and often nausea and vomiting. Several times we observed a faint icteric coloring and in some cases the appearance on neck and breast of an exanthema resembling measles. As a rule the attack begins 4-5 hours after the injection and lasts 12-15 hours. In exceptional cases it may begin much later, but then it is not nearly so intense. The patients experience remarkably little weakness from the attack and feel relatively well as soon as it is over, generally better than they did before it came on. The local reaction can best be observed on those patients whose tuberculose affection is plainly visible, for instance those afflicted with lupus. In them changes take place that prove the specific antitubercular action of the remedy in a most surprising way. The diseased portions of the skin in the face, etc. begin to swell and turn red even before the attack of chills set in, although the injection is made under the skin of the back, a point decidedly remote from the affected parts. The swelling and reddening increases during the fever and can attain a very marked degree so that the lupus-tissue turns reddish brown and necrotic. In the case of more sharply defined lupus centres the more swollen and dark red parts were edged by a white seam nearly a centimeter wide and this again was surrounded by a wide bright red border. The swelling of the diseased parts gradually decreases after the cession of fever and may have entirely disappeared after 2 or 3 days. A serum exudes from these lupus-centres and, drying, forms a crust on them which changes into scabs that fall off in 2-3 weeks and sometimes leave a smooth red scar after a single injection. Generally several injections are necessary to effect a complete removal of the lupose tissue, but of this I will speak further on. It is very important to note that the changes during this process are exclusively limited to the portions of the skin affected by lupus; even the faintest and smallest bits of diseased tissue go through the entire process and become visible on account of their swelling and reddening, while the actual scab-tissue in which the various stages of lupus have been completed remains unchanged. The observation of the treatment of lupus with the remedy is so instructive and must be so convincing as regards the specific nature of the remedy that every one wishing to occupy himself with the study of this remedy should if possible make his first experiments with lupus. Less marked, but still apparent to the eye and touch are the local reactions in tuberculosis of the lymphatic glands, of the bones and joints, etc., in which case swelling and increased painfulness, and in the more superficial parts also a reddening can be observed.
