The delay in the manifestation of remedial change from November to March arose from complete blockage of the nose, and until the space created by the subsidence in the size of the polypi sufficed for a passage of air the patient had no reason to acknowledge relief. In the treatment, both of swollen tonsils and in that of nasal polypi, the prescriber will be led away at the onset who accepts the testimony of the patient alone; he should make careful inspection of the parts, and be guided by what is often but a slight local change, as well as by concomitant, and it may be remote, symptoms. 2. The next case I have to bring forward is one of ozoena in a girl of sixteen, who had been three years under the treatment of a colleague who kindly sent her on to me for treatment at the London Homoeopathic Hospital. The girl, whose occupation was a teacher, has had ozoena since three or four years old. The odor complained of was horrid, and the discharge excessive; a most unpleasant smell in the nose and nasty taste in the mouth; she takes cold easily if out in the night air or damp, and her nose, at times, gets stuffed up; bowels irregular; catamenia only twice--once three months ago and two months before that. On December 30, 1893, I prescribed _Lemna minor_, and she returned to me from the country, where she was living, on the 31st of the following March, imploring me for another powder, as she had been almost well for two weeks after the last and then had relapsed to her old state; breathing is short and is low spirited. 21st of April, very much better; odor not nearly so bad, discharge much less; unmedicated pilules, three times a day. 19th of May, 1894, kept better for a month; took cold two weeks ago, and since then throat has felt thick and nose has discharged with a horrid odor. Catamenia regular. Breathing is better; crusts coming from both, worse on the left side. To have _Lemna minor_. This patient came from a distance which prevented frequent attendance, but the above is quite sufficient evidence of the power possessed by _Lemna m._ in acting upon the nasal mucous membrane. In both these cases relief was immediate after the administration of the dose, and in neither case could any reasonable doubt exist as to its being drug effect. In some cases I have known a certain disturbance of the bowels to set in after a dose of _Lemna_, but this effect of the remedy is not sufficiently pronounced to be able to say much about it. Still it is interesting to narrate one or two experiences, especially as in the first of these, at all events, the concomitants were interesting.
