A writer in a medical journal says: "Beware of too much quinine. It will produce a congestion of the ear and irritation of the auditory nerve. The common habit of taking quinine for neuralgia and other ailments without consulting a doctor is altogether reprehensible, and may lead to very serious results. Many cases of deafness are produced by overdoses and long-continued use of this drug." Aprysexie is the name Dr. Guye, of Amsterdam, chooses for inattentiveness, and he quite singularly finds that the nose is a cause of it. A dull boy became quick to learn after certain tumors had been taken from the nose, and a man who had been troubled with vertigo and buzzing in the ears for twelve years found mental labor easy after a like operation. In a third case a medical student was similarly relieved. Dr. Guye supposes that these nasal troubles affect the brain by preventing the cerebral lymph from circulating freely. =Elixir Brown-Sequard.=--The way Brown-Sequard uses this medicine is entirely successful. Do not think because others have failed that the principle is wrong. Most experimenters, first, are not careful in getting perfectly healthy specimens of animals from whose vitals the elixir is made, while, secondly, they expose the liquid and allow it to become filled or impregnated with microbes and various foreign elements. The process of administration is thus described:-- The syringe punctures the cuticle, or scarf-skin, and the cutis, or true skin, and then enters the subcutaneous or cellular tissue which covers the muscles, or flesh. Through all the tissues of the body run the lymphatics, which convey the injected matter to the lymph channels, these in turn to the veins, and thence throughout the system. A half ounce of the fluid will be distributed in from one to three hours. Sometimes the subject might feel the stimulus very quickly, and in some cases hours might elapse before any effect was felt. The human system is able to absorb almost an unlimited amount of this liquid, if administered properly and if pure.
