I never made a diagnosis in this case; have not reached one yet, nor am I grieving over that omission. I did rashly declare that it was not epilepsy, because Sauvages _tympanites intestinalis_ is a feature of hysteria, but not of epilepsy. But not a word of this was said to the patient. It was not a "mind cure," for I have no "mind" to spare; nor was it "Christian science," for I am not up to that. I had an _amnesis_ in which grand-mother and grand-daughter participated. Nature had put the "key-note" in italics, not only in the patient but also in the drug. Thacher stumbled upon it empirically; Hering found it pathogenetically, and that led to its application under the guidance of the only approximation to _a law_ in therapeutics that has yet been discovered by any of woman born: _similia similibus curantur_! (Anent the foregoing paper Dr. W. C. Campbell sent the following to the same journal:) POTHOS FOETIDA, HYSTERIA. November 6, 1889, was called in haste to see Miss N----, aged 19 years. Found her lying upon the floor, exhibiting all the phenomena of epilepsy, clenched hands, frothing at the mouth, clonic spasm, etc. On questioning the family, I learned that she had been subject to such seizures for about two years, and that they were increasing in frequency. She had been dismissed from the various cotton mills in which she had been employed because of them. The father had been informed that she had epilepsy, and she had been treated accordingly by three old school physicians. The sister informed me that although she had frequently fallen near the stove she had never struck it. Further questioning elicited the fact of her never having injured herself more seriously than to bite her tongue. It was then I became suspicious, and later felt convinced that it was hysteria and not epilepsy with which I had to deal. I remembered having read in _The Recorder_ an article by Dr. S. A. Jones, of Ann Arbor, on _Pothos foetida_, with the record of a case in some respects similar to mine. After again reading it up, I made a tincture of the roots and tendrils gathered at the time, of which I gave her a two drachm phial, directing her to take ten drops three times per day. On the second day she had a slight seizure while at dinner. After two months she again resumed her place in the mill, where she has since been steadily employed, and is strong and well in every way. Have used _Pothos_ in epilepsy, also in dropsy, with negative results. PRIMULA OBCONICA. NAT. ORD., Primulaceæ. COMMON NAME, Primrose var. obconica.
