Persons who have travelled in far of
 lands have been bringing back with them for some time now startling accounts
 about the stimulating properties of va
 rious plants. of W hich the native popula-
 ton make use to enable them 10 furnish a considerable amount of work without
 taking any food. Thus. ln Sonlh Amer lea they tell us ot the ceca, mate and gnrsno plants; in Africa of the kola nut. and in Asia of tea and coffee. h Eu- rope NC have, of course, endeavored 10 verify and 10 utilise the precious quali- ties Of these natural products; tea and coffee have entered into common. use, especially as intellectual slimulants, and several recent experiments show clearly what services these substances can ren- ner 10 facilitate muscular work.
 But the researches carried oat by eheusss have made t known that nearly al of These plants with Ihs exception of aies, such as the coca. contain caffeine. lis therefore in the study oi the physt ologica! properties of this slkalo,d tha, we ind the explanation Of these sprar- ent'y supernatural phenomsna.
 A number Of physiologis,s have a. ready taken up the question, bu, in their publications we find nothing but contra diotsons ea contradictions. According tc some of them she specific action of the poison affects only the muscles: ae- coFding to others it acts extensively on the nervous system.
 li has become more impogtan, than ever 10 opsn this question anew now that NC ale endesvo'ing to utihze 10 the army the properties Of caffeine and to try 10 ind out wore exactly the manner "A which Il acts or the nuuitiye functions NJ. See has been making experiments with species of cake made made out oi kola nut, and which Prof. Hsckel has already uIed with success m the army. He has come to the conclusion that caffeine and lts derivatives possess tue two soIlcwing properties;
 I. They facilitate muscular work and allow il to be kept up for long lime without fatigue.
 ?. They allow us 10 go withou, food for considerable length of tune when we have anything to do requiring q | great deal of eXestion.
 Experiments made on a series of thirty individuals in good health and without sign of cardiac or pulmonary | disease, have shown that ID the gener- alty ot cases the exeiton of running does not modify the respiratory rhythm in persons under the influence of caf- teine; whereas. withou, caffeine ,he loss of breath increases the number of res- pirations ,hreeiold. In word, il can be said that csileine places man who IS not h training in the condition of trained athlete.
 Caffeine prevents loss of breath and paipilauons after an exertiou, and this is a point of no small importance Any one going through any violent and pro- ionged exgrciss IS, is ss sss its use, put on the same footing with person having Isge6 a course ol framing.
