Rh languished, and the return fell off immediately to one third. Estimating the quantity of metal that produces this effect, it was found that the addition of one part of iron was sufficient to determine the production of a weight of plant nearly nine hundred times as great. The suppression of the iron further caused an irreparable loss, for when it was sought to remedy the wilting of the plants by restoring the iron which had been taken from the medium—an experiment which had been successful with higher plants—the attempt was a failure, and the plants could not be prevented from perishing.

These facts are full of interest in themselves, and they further show well the necessity or utility of iron in plant life, but they teach us no more. They reveal nothing of the mechanism of the action, and if we wish to penetrate further in the matter we always have to turn to animal physiology.—Translated for the Popular Science Monthly from the Revue des Deux Mondes.

 

GENTLEMAN who had lived for several years among the Indians of the Canadian northwest said that he went among them believing they were an untutored race. But when they told him of a dozen kinds of berries growing in a locality where he knew but two, brought him flowers he could not find after careful search, and around their council fires showed as deep an insight into the mysteries of life as the savants of his university, then he concluded they could no longer be called untutored.

And why should they be? Is there no culture or civilization outside of the enlightenment of Europe or America? And because a civilization does not exactly fit the grooves in which most of the world has moved, may it not be a real civilization for all that? If such is possible,-then we vote, the Malays a cultured people. Of course, their culture is not like our own; it knows no railroads, no telegraphs, boasts of no intricate political machinery, has no complicated social despotisms. Native princes rule for 'the most part over peaceful states, and politics means no more than the regulation of quiet village life. But what need of railroads, when the rivers are avenues of trade and communication? Why telegraphs, when the world is bounded by the jungle horizon? Or why, in short, severe civil and social enactments, when the common Wahlspruch of life is, "Fear disgrace rather than death"? Such a civilization, we admit, is a humble one; but
