"In cases of injury from scalding, get a large oyster and put it in a basin with its mouth upwards somewhere quite away from anybody. Wait till its shell opens, and then shake in from a spoon a little Borneo camphor, mixed and rubbed into a powder with an equal portion of genuine musk. The oyster will then close its shell and its flesh will be melted into a liquid. Add a little more of the above ingredients, and with a fowl's feather brush it over the parts and round the wound, getting nearer and nearer every time till at last you brush it into the wound; the pain will thus gradually cease. A small oyster will do if a large one is not to be had. This is a first-rate prescription. "Where a man has fallen into the water in winter, and has quite lost all consciousness from cold, if there is the least warmth about the chest, life may still be restored. Should the patient show the slightest inclination to laugh, stop up his nose and mouth at once, or he will soon be unable to leave off, and it will be impossible to save him. On no account bring a patient hastily to the fire, for the sight of fire will excite him to immoderate laughter, and his chance of life is gone. "In cases of nightmare, do not at once bring a light, or going near call out loudly to the sleeper, but bite his heel or his big toe, and gently utter his name. Also spit on his face and give him ginger tea to drink; he will then come round. _Or_, Blow into the patient's ears through small tubes, pull out fourteen hairs from his head, make them into a twist and thrust into his nose. Also, give salt and water to drink. Where death has resulted from seeing goblins, take the heart of a leek and push it up the patient's nostrils--the left for a man, the right for a woman. Look along the inner edge of the upper lips for blisters like grains of Indian corn, and prick them with a needle." The work concludes with an antidote against a certain dangerous poison known as _Ku_, originally discovered by a Buddhist priest and successfully administered in a great number of cases. Its ingredients, which comprise two red centipedes--one live and one roasted--must be put into a mortar and pounded up together either on the 5th of the 5th moon, the 9th of the 9th moon, or the 8th of the 12th moon, in some place quite away from women, fowls, and dogs. Pills made from the paste produced are to be swallowed one by one without mastication. The preparation of this deadly _Ku_ poison is described in the last chapter but one of Section III. in the following words:-- "Take a quantity of insects of all kinds and throw them into a vessel of any kind; cover them up and let a year pass away before you look at them again. The insects will have killed and eaten each other until there is only one survivor, and this one is _Ku_."
