_Lemna minor_, CASE I. A lady, aged forty-seven, two years previously met with an accident; a sign board fell on her head when out walking in the street. Seven days after that was taken with sneezing attacks, suffered from nasal catarrh with little intermission until March, 1893, when she came under my care. _Psorinum_ 30 soon put a different complexion on the case, and she became so far relieved of her trouble (which has made her life almost unbearable, as she never dared make an appointment for fear of an attack coming on) that she discontinued treatment. Last Christmas a sharp attack of influenza brought back the catarrh, and this time it proved less amenable to treatment. Fears of polypus distressed the patient, though I could not discover any. However, she again made progress, but scarcely as rapid as I could have wished, when I thought of giving her _Lemna_ on indications given by Dr. Cooper. On February 15, 1894, I gave it in the 3x, one tablet four times a day. February 22, very much better; has felt freer in the head than at any time during the last ten years; has felt very much better generally; spirits braced up. She steadily progressed to cure, and by March 15th could endure the smell of strong scented flowers, which before was impossible. CASE II. Captain B., aged forty-four, consulted me on February 29, 1894, for violent neuralgia on the right side of the neck, the part being exquisitely sensitive to touch. He had cough and cold for a month. On getting up in the morning he filled two pocket handkerchiefs with yellow deflusion before he got his nose clear. I gave him _Bell._ 12 to take till the neuralgia was better, and then told him to take _Lemna_ 3x gtt. j. three times a day. On March 9th he reported that the _Bell._ speedily took away the neuralgia, and that then the _Lemna_ cleared off the catarrh in a most astonishing fashion. He never had a medicine to act so magically before. _30 Clarges street, Piccadilly, W., April 21, 1894._ The next communication that I have to bring forward is one from Dr. J. C. Burnett: Dr. Cooper told me that he had relieved a case of nasal polypus with _Lemna minor_, and having several cases of the kind that had long been under my observation I thought it my duty to give them the benefit of _Lemna_. CASE I. A gentleman of sixty years of age, with nasal polypus only moderately developed, yet of many years' duration, was much troubled by the chronic nasal obstruction which was markedly worse in wet weather. I gave him _Lemna_ 3x, five drops in water, night and morning. Returning in a month, he exclaimed: "That is the best tonic I have ever taken; I have never taken any medicine in my life that has done me so much good. I feel quite comfortable in my nose and can breathe through it quite well."
