Plants have the power of movement to adjust their surfaces to a proper angle with impinging light rays, as a protective adaptation.
Matches which do not contain any phosphorus and which take fire by friction on any surface—a match that has been long sought—have been prepared by Mr. S. A. Rosenthal and Dr. S. J. von Kornocki. It is represented that they can be manufactured as cheaply as ordinary matches.
[THE STONE AGE IN EGYPT.]
By J. DE MORGAN.
The investigation of the origin of man in Egypt is a very complex problem, belonging as much to geology as to archæology. The earliest evidences we have of human industry, in fact, go back to so remote a period that they should be regarded rather as fossils than as archæological documents. They are very coarsely worked flints, which are found near the surface of the ground among the pebbles of the Quaternary or Pleistocene epoch, and similar to those which occur abundantly in Europe, America, and Asia; but the study and collection of them have been pursued with less method than in those countries. The more recent monuments, so much more conspicuous and more easily accessible, have attracted most attention, while these have been left in the background.
No region in the world presents a clearer and more distinct individual character than Egypt. Each village is a special world, each valley a universe that has developed its own life; and man has felt the special local impressions; and even in modern times, while all the Egyptian villages present a similar aspect, and although the fellah appears to be the same sort of a man everywhere, each locality has its special individual characteristics. One who knows how to observe men and things critically will find considerable differences. These dissimilarities are as old as Egypt itself. They have always existed, and are as much more intense as the communications between district and district were formerly more difficult. They are due to physical conditions special to each village, to the prevailing winds, the form and character of the mountains, the extent of cultivable lands, and the supply of water. A study of the detail of the country is a very important preliminary to the examination of Egyptian history. Every village and every nome had formerly its special divinity and its particular usages. Are we sure that the gods and customs were not imposed by local conditions? At Ombos two hostile gods were adored in the same temple. May we not see in this fact a recollection of the hostility which has always prevailed between the inhabitants of the two banks of the river, and still continues?
Previous, however, to investigating these details which have been so influential on Egyptian civilization, we ought to dispel the darkness which hides from us the earliest traces of man in the valley of the Nile, and examine how man lived in his beginning, to study the geology of the country and its condition when it issued from the seas. As one of the results of this study we find that palæolithic man, known to us only through the rough-cut flints we find in the alluvions, made his first appearance. After this period of excavation came that of filling up with silt, which still continues. New evidences of man appear in his burial places and the ruins of his villages, the kitchen middens which he has left in his habitations of unburned brick and in his camps. This time he is more civilized; he chips his flints with a skill that is not surpassed in European neolithic implements; he makes vessels of stone and clay, covers them with rude paintings, sculptures animal forms of schist, and wears necklaces of the shells and the stones of the country. Then comes a foreign people to take possession of Egypt, bringing knowledge of metals, writing, hieroglyphics, painting, sculpture, new industries and arts that have nothing in common with the arts of the people it has overcome. The ancient Pharaonic empire begins, or perhaps the reign of the divine dynasties. The men with stone implements are the aborigines; the others are the conquering civilized Egyptians. Nothing can be more interesting than a comparison of the arts of the aborigines and those of the Egyptians of the earlier dynasties. Nearly all their characteristics are different, and it is impossible to regard them as of common origin. Yet some of the native forms persisted till the last days of the empire of the Pharaohs. These aborigines belonged to a race that is now extinct, they having been absorbed into the mass of the Egyptians and Nubians among whom they lived, and from this mixture the fellah of ancient times is derived. The origin of the conquering race—of the Egyptians as we know them—has not been precisely determined. The weight of evidence, so far as it has been obtained, and the balance of opinion, are in favor of an Asiatic origin and of primary relationship with the Shemites of Chaldea.
