GEOGRAPHY IN RUSSIAN HISTORY

WILLIAM E. LINGELBACH
THE history of Russia affords a striking example, not only of the influence of geography on history, hut of the fact that man's place in the scale of civilization is in large measure determined by his environment. In speaking of the contrasts in the development of Russia as compared with England, a recent writer says:

PROFESSOR JOHN J. STEVENSON
WHILE reading discussions of modern field and office methods, published in Economic Geology, I became impressed with the feeling that some notes, historical and reminiscent, respecting conditions and methods of forty and more years ago, should be placed on record for the benefit of the younger geologists.

PROFESSOR DUNCAN S. JOHNSON
The native flora of Cinchona Hill is a varied and interesting one. Being south of the-mountains, and on a sharp ridge with perfect drainage, the soil often gets quite dry. Especially is this true of the small pockets of humus in the rock clefts occupied by the numerous rock xerophytes, and of that gathered on the limbs of trees or held among the clustered roots of epiphytic orchids.

CHARLES A. EASTMAN
THE physical decline and alarming death rate of the American Indian of to-day is perhaps the most serious and urgent of the many problems that confront him at the present time. The death rate is stated by government officials at about 30 per thousand of the population—double the average rate among white Americans.

HENRY DWIGHT CHAPIN
THE rich contribution that animal experimentation has yielded to the direct, curative treatment of disease is well known to all educated physicians. The lay public, however, seem to be insufficiently informed as to the many benefits that have been derived from this method of scientific investigation.

WILLIAM J. ROE
THUS, half a century ago, he forecasted what is now happening on the other side of the Atlantic, who was perhaps America's most subtle reasoner. He is commonly classed as a poet—this man, Walt Whitman—lauded as such, reviled as such. He was really a prophet; though, as it is presumed to be well known, "High Criticism" in final analysis declares that the words prophet and poet are synonyms.

H. W. FARWELL
EDUCATION is properly preparation for service. That man who enters upon his work with a poor idea of what is required of him is at once seriously handicapped and often prevented from reaching a goal which he hopes to reach, and strives to attain, sometimes with an enormous waste of energy.

DR. SHEPHERD IVORY FRANZ
IT is well known that sensory stimuli are not always correctly appreciated, and that under certain conditions errors of judgment are made. These errors of perception which are not infrequent with normal people are called illusions and hallucinations.

FIELDING H. GARRISON
In the first half of the nineteenth century the accepted view of the phenomena of secretion was that enunciated by Johannes Müller, viz., that the process consists of two phases—secretion proper, or the casting out of substances upon a surface inside the body, as in the case of the gastric juice; and “excretion” or the voiding of such secreted substances into the external world, as in the case of bile or urea.

THE American Association for the Advancement of Science and the national scientific societies affiliated with it meet at the University of Pennsylvania, Philadelphia, during the week beginning on December 27. In view of the scientific attractions of Philadelphia and its central situation for those living on the Atlantic seaboard, with convenient access for those living further west, the meeting is sure to be of outstanding importance.
