xliv foreign drugs imported into the markets of Europe would soon be superseded to a great extent, if the properties of European plants were carefully examined. It is contended, in illustration of this opinion, that Salicine, obtained from our native Willows is equal in energy to Quinine, and that it is formed by Providence in low marshy places exactly where remittent and intermittent fevers are experienced most frequently, and with the greatest severity. * * * * * * * *

"Such a subject of investigation is by no means unimportant when it is considered * * * that exotic drugs are not only costly, but often so much adulterated as to be unfit for use * * * *

"It by no means follows that plants are inert because medical men have reported unfavourably of their action. The most powerful species have had their energy destroyed by unskilful preparation, or by not knowing at what season to collect them. ****** the very nature of the climate of tropical countries generally causes the properties of plants to be more concentrated and completely elaborated than in Northern latitude."

So far the indigenous drugs have not been carefully and systematically studied. The Executive Committee of the Calcutta International Exhibition for 1883-84, reported that "it must be admitted that our ignorance of the properties and uses of indigenous drugs is scarcely pardonable. It seems highly desirable that the whole subject should be gone into with greater care than has yet been done, both with the view of weeding out the worthless from the good, and of preparing the way for a number of the better class native drugs taking the place of some of the more expensive and imported medicines of Europe. It seems remarkable that so large an amount of aconite should be collected in Nepal and exported to Europe, in order to be re-imported into India before it can find its way to the poor people who crowd around our dispensaries. Illustrations of a similar nature can be multiplied indefinitely. Atropa Belladonna, the deadly nightshade, for example, is a common weed on the Himalayas from Simla to Kashmir, yet every ounce of the drug used in India is imported from Europe, the Indian plant having apparently been entirely overlooked."*
