IT is evident to any one who has kept abreast with the recent progress in psychology that the advance in the knowledge of mental processes has been greatly aided of late by contributions from certain collateral branches of science. The older method of introspection had, indeed, resulted in establishing many facts and in formulating numerous laws of psychical action.

GARRETT P. SERVISS
FOLLOWING the order of right ascension, we come next to the little constellations Crater and Corvus, which may be described as standing on the curves of Hydra (map Ho. 8). Beginning with Crater, let us look first at a, a yellow fourth-magnitude star, near which is a celebrated red variable R.

THE SUCCESSOR OF THE RAILWAY.

APPLETON MORGAN
WITHIN the few years remaining to the nineteenth century, if not indeed already, will certainly pass away the human being who can remember a date when there were no railways. A railway then will be, if it is not already, as much part of a natural landscape as a mountain or a river, since no one can then recall a time at which railways as well as rivers did not run.

R. W. SHUFELDT
AS in all other departments of biology, the classification of birds was not placed upon a rational basis until midsummer of the year 1858. It was at that time that Darwin and Wallace demonstrated the principles of the law of organic evolution, and gave to the world of science their views upon it and the results of their labors.

STUDIES OF CHILDHOOD.
VII.—LATER PROGRESS IN LANGUAGE.

JAMES SULLY
IN a previous paper I traced some of the earlier steps in the child's acquisition of language. In the present study we may follow him in his later and more ambitious linguistic efforts. The transition to this higher plane is marked by the use of the complete form of thought or sentence.

REUBEN POST HALLECK
WHETHER there is any such entity as absolute truth we leave for the metaphysician to determine. Out of a vast number of factors which may affect truth in general, we here select a few which are to-day deflecting and limiting human truth. There are factors inherent in the self at its present stage of development, or, more broadly speaking, certain psychical laws which man’s present nature will not allow him to change or to evade.

DR. C. HANFORD HENDERSON
IT will be remembered by those familiar with biblical lore that when Saul, the son of Kish, went forth in search of his father’s asses, he found, instead of these humble animals, a kingdom and a crown. Not every man is so fortunate. Indeed, as we all know, the experience is often reversed.

THE study of paleontology and prehistoric archaeology and the exhumation of the life of the past in caverns have been pursued in France during the last twenty years at the expense of the investigation of the present life, while the fauna and flora of their black recesses and dark waters have nevertheless flourished quite as vigorously as in the subsoils of Austria and America.

AS the sun, at the close of his winter’s recession, marches into higher latitudes, he awakens in successive zones both animal and vegetable worlds to the full activities of their being, and exerts, even in their remote and hidden seclusion, his influence upon the finny inhabitants of the deep.

COMMUNICATED INSANITY.

CHARLES W. PILGRIM
FOR several weeks past it has heen scarcely possible to take up a paper without seeing such startling headlines as "Triplets, and all Crazy," "Three Daughters become Maniacs,” etc. In fact, so much publicity has been given to the rather unusual number of cases of communicated insanity that have recently occurred in New York, Buffalo, and Philadelphia that the subject has become one of general interest and one upon which accurate information should be given.

WE do not know a more encouraging sign of the times than the vastly improved entente now existing between those two forces, which only a generation ago seemed to many to be irreconcilable enemies—science and religion. There were not wanting, at the time we speak of, wise men who asserted that the conflict between these two must be the result of misunderstanding; but, in general, the partisans of religion were convinced that any science, so called, which threatened their special beliefs must be absolutely false, while some at least of the partisans of science were disposed to hold that, because some specific theological tenets had been proved unsound, the whole basis of religion had been shattered and destroyed.

PROF. OSBORN has undertaken in this work the interesting and useful task of tracing from the earliest times down to the present day the course of speculation and discovery which resulted in the establishment of the Darwinian theory of the origin of species by natural selection.

THE process of manufacturing calcium carbide by heating in an electric furnace a mixture of coal dust and lime is now well known. The appearance of this material, in masses, is like that of the mineral serpentine, it being greenish gray in color, with a luster like that of feldspar.
