During the spring of 1886 scarlet-diphtheria appeared in this place. On March 28th I was called to attend the 8-year old son Matthias, of Wernerus, a weaver, in the hamlet of Niepert, that showed symptoms of the above disease. Cynanche was at high degree, and the throat was filled with diphtheritic coating, so much so that I had reason to fear the worst, on account of the accompanying fever and of the choked-up condition and weakly (scrofulous) habit of the patient. But the well-known remedy of Viller, given alternately with _Belladonna_, proved itself also in this case, and the symptoms in the throat assumed, after a few days, a less dangerous character. Not so with the fever, which gradually assumed the form of typhoid, and ran very high, while the scarlet-rash grew quite pale. On the morning of April 5th, his temperature was 42.5°, the patient unconscious, the pulse weak and intermittent, the feet swollen. Upon inquiry the parents told me that the boy urinated very little. His urine, of which I had taken a quantity the day previous for examination, contained a considerable amount of albuminous sediments. I prescribed _Kali arsenicosum_ in the fourth centesimal potency, which had been recommended in similar cases by Dr. Hock in the international homoeopathic press; but, although the temperature decreased after using this remedy, the dropsical swelling of the feet increased more and more, and after a few days the entire body of the patient was swollen very much. The discharge of urine grew continually less. Under these circumstances I examined the patient again thoroughly, and found great sensitiveness of the kidneys against pressure, in spite of his otherwise apathetic condition. These symptoms reminded me of _Virga-aurea_. This remedy was immediately applied, and I had no reason to regret it. Within one day the urinal discharge became profuse, the general condition improving at the same time; the peeling off took place without further trouble, and after the patient had taken _Virga-aurea_ for two weeks, and, on account of anæmia, for one week three times a day, a dose of _Ferrum peroxydatum_ in the 2d trituration, he had so far recovered that I did not consider it necessary to give further medicine.
