I should add, that the fiber at times entirely _disappears_ from the cavity (by _contraction_, of course), when again it is seen suspended as before. This is one reason why it is believed to be a _worm_, and supposed to _creep_ up and down in the flesh. Treatment of Diseases--Diarrhoea The treatment of fever in this part of Africa should be the same as that in Liberia, given on page 280. The best remedy which I have found for diarrhoea is: [TN: symbol: Rx]. Pulv. Rad. Rhei. [TN: symbol: drachm] j.; Syr. Simp. [TN: symbol: ounce] jv.; Spts. Terebinth, [TN: symbol: dracm] j.; Tinct. Opii., gtt. x. M. ft. Pulverized rhubarb, one drachm, (or one-eighth of an ounce); simple syrup, four ounces (or eight large tablespoonfuls); laudanum, ten drops; spirits of turpentine, one spoonful. Mix this well together to take. Dysentery For dysentery the recipe is: [TN: symbol: Rx]. Pulv. Rad. Rhei. Pulv. C. Catech. a. a., [TN: symbol: drachm] j.; Syr. Simp. f. [TN: symbol: ounce] jv.; Spts. Terebinth. Spis. Ammon. Arromat., a. a. f. [TN: symbol: drachm] j.; Tinct. Opii. gtt. x.M.ft. Pulverized rhubarb and pulverized gum catechu, each, one-eighth of an ounce; simple syrup, eight large tablespoonfuls; spirits of turpentine and aromatic spirits of ammonia, of each one teaspoonful; laudanum, ten drops. Mix this well together to take. Of this take one teaspoonful (if very bad, a dessert spoonful) every three hours, or four times a day (always beginning at least one hour before breakfast), till the symptoms cease. Fever Antidote During the presence of febrile symptoms, in the absence of all diarrhoea and dysenteric symptoms, even when the person is not complaining, an excellent simple antidote to be taken at discretion, not oftener than once every hour during the day, is: [TN: symbol: Rx] Syr. Simp., [TN: symbol: ounce] jv.; Spts. Ammon. Arromat. [TN: symbol: drachm] jss. M. ft. Simple syrup, eight large tablespoonfuls; aromatic spirits of ammonia, one and a-half teaspoonfuls. Mix this well together. Take a teaspoonful of this preparation in a little cold water, or a glass of lemonade if preferred, and the condition of the bowels will admit, as often as thought advisable under the circumstances. I have thus thought proper to simplify this treatment, that it may be in the reach of every person going to the tropics, as I am certain that there has been a great deficiency in the treatment and discovery of remedies in diseases of that continent especially. These prescriptions, as compounded, are entirely new, originating with the writer, who has only to add that he is in hopes that they prove as advantageous and successful in other hands as they have been in his.
