    Tanret, therefore, has proposed a more stable combi- nation of caffeine with salicylate or benzoate of soda. The first contains 45 per cent, caffeine, the second 61 per cent. These coinbinations being quite soluble, and having no local irritant action, may be used by the subcutaneous method. These are the formulae which Tanret has proposed. 5 Benzoate of soda, 2.95 (gr. xliv). Caffeine, 2.50 (gr. xxxvi). Distilled Water, 6.00 (gr. xc). M. Fiat Solutio. Each syringeful, or about 15 minims, contains a full dose of caffeine. (In other words, a cubic centi- metre [about 20 drops] has 25 centigramms). The second formula is as follows: B Salicylate of soda, 3.10 (gr. xlvii). Caffeine, 4.00 ( 3 i). Distilled Water, 6.00 (3 jss). M. Dissolve with the help of heat. Each cubic centi- metre contains 40 centigrammes caffeine. You need, however, resort to the hypodermic method only in exceptional cases, as when the patient is taken with vomiting, or when the caffeine provokes gastric irritation and pain. Ordinarily the caffeine may be given in pills, in granules, in capsules, or in potion. The pill form is not much employed. This results from the fact that the pills may pass through the in-
