COCA TEA OR INFUSION.—A teaspoonful of the _Thé Mariani_, added to a cup of hot water, sweetened to the taste, with or without the addition of cream or milk, makes a very agreeable drink, more digestive, more tonic, and less exciting than coffee or tea, while possessing in a higher degree the tonic and stimulating properties of those two substances. It is in this form that Coca is especially used in Peru and Bolivia, where it is preferred to the Chinese tea. Persons who drink Chinese tea at meals may advantageously substitute the _Thé Mariani_ for it. For patients who cannot generally take milk, it is advisable to add _Thé Mariani_. Excellent results will be obtained. COCA GARGLES AND SPRAYS.—Independently of its tonic and reconstituent action, Coca possesses anæsthetic and soothing properties that have been observed and made use of in practice by laryngologists in the form of a spray, in the proportion of a teaspoonful of _Thé Mariani_ to half a glassful of warm water. An ambulance physician of Tonkin, who has experimented with _Thé Mariani_, sends the following note: "_Thé Mariani_ has rendered us real service during expeditions as well as in hospital practice; on the march it makes with boiled water, with or without the addition of sugar, a very agreeable, tonic and stimulating drink; a veritable reserve food, it takes the place of alcoholic drinks and insufficiency of food, and aids the men in bearing the most distressing fatigue. The water of swamps, rivers or ditches, mixed with a few spoonfuls of _Thé Mariani_, could be drank without any inconvenience, and assuaged thirst. "_Thé Mariani_ stimulates the appetite, overcomes atony of the digestive organs, and prevents and combats diarrhœa efficiently. "Mixed in small quantity with fresh or condensed milk, it gives it an agreeable taste and causes it to be borne by the most delicate stomachs; hence it becomes a valuable adjuvant in the treatment of the endemic dysenteries and diarrhœas of tropical countries. "Finally, its exclusive use, even its excessive use for several days, has not seemed to us to exert any injurious influence on the system, as the abuse of coffee or of alcoholic drinks had certainly done under like circumstances." Dr. Fordyce Barker, Dr. J. H. Douglas, Dr. Henry B. Sands and Dr. Geo. F. Shrady have authorized us to make known that it was due to _Thé Mariani_, added to milk (in the proportion of a teaspoonful of the _Thé_ to a cup of milk), that they were able to nourish Gen. Grant, the ex-President, when he was unable to support any other food. By this means they succeeded in prolonging the life of their illustrious patient for several months.
