DR. KNERR: I have always used Variolinum to prevent smallpox. I had the peculiar case of a woman of about fifty to whom I gave Variolinum and promptly she developed a beautiful pustule on her right arm. It was during an epidemic, and she never had any further symptoms.
I wish to speak of another thing. It is known that the chemical constituents of the saliva contain the sulphur cyanide of potassium, and it was discovered in an epidemic in Philadelphia that where silver plating was done, where they used the cyanide of potassium no cases of smallpox occurred at all among the workers. This started Dr. Hering to investigate the cases of smallpox in the smallpox hospital in Philadelphia. He went there and examined their saliva, and found that the cyanides had left the saliva, but he found the cyanide in the pustules, and as soon as the patients got better the cyanides left the pustules and went back to the saliva.
That started him to use the sulphur cyanide of potassium in liquid which, when sprinkled around on the sheets in the sick rooms, had the effect that there never was another case that did that. I myself did a great deal of practice in that line at that time.
Then Dr. Hering wished to find a remedy from a plant. He thought a medicine derived from a plant that contained the sulphur cyanide of potassium would contain the remedy, and he found it in the black mustard, the Sinapis nigra.
DR. HUBBARD: I want to thank Dr. Knerr for having spoken to us. Also, I shall certainly remember the sinapis nigra. It was entirely new.
I agree with Dr. Lewandowski that the remedies which come out sixth or seventh in the repertory, if they are rare remedies that stand high, are extremely important. I am more likely to give the one that comes out No.3 than the one that comes out No.
I personally feel that in every case we take I hope we take it according to Dr. Spaldings wonderful method, that we should consider which of the nosodes of the fundamental miasms most closely are related to that case. We know that the remedies are grouped around the miasmatic divisions, and we should have a care to that in our thought of the remedy.
Of course, Dr. Farrington was right when he said that my cases were chronic rather than acute, but they were in the acute stage at the moment. After all, I suppose every case is really chronic, no matter how acute it seems.
