E. B. TYLOR
A NTHROPOLOGY finds race-differences most clearly in stature and proportions of limbs, conformation of the skull and the brain within, characters of features, skin, eyes, and hair, peculiarities of constitution, and mental and moral temperament.

EUROPEAN SCHOOLS OF FORESTRY.

[no value]
N. H. EGLESTON
THE word “forestry” has not yet come into familiar use in this country, and its meaning is understood only by the few; “school of forestry” is still less comprehensible. It is only natural that our people, occupying a region covered to a great extent with a dense and varied growth of trees, in regard to which no apprehension of deficiency has been suggested until within a comparatively short time, should have entertained little thought of the forest as a thing to be specially cared for and cultivated.

PRODUCTION OF SOUND BY RADIANT ENERGY.

ALEXANDER GRAHAM BELL
AT the time of my communication to the American Association the loudest effects obtained were produced by the use of selenium, arranged in a cell of suitable construction, and placed in a galvanic circuit with a telephone. Upon allowing an intermittent beam of sunlight to fall upon the selenium, a musical tone of great intensity was produced from the telephone connected with it.

FELIX L. OSWALD
THE vital processes of man, like those of all his fellow-creatures, are partly controlled by automatic tendencies. Some functions of our internal economy are too important to be trusted to the caprices of human volition; breathing, eating, drinking, and even love, are only semi-voluntary actions; and during a period varying from one fourth to two fifths of each solar day the conscious activity of the senses undergoes a complete suspense: the cerebral workshop is closed for repairs, and the abused or exhausted body commits its organism into the healing hands of Nature.

THE DEVELOPMENT OF POLITICAL INSTITUTIONS.
VIII.—CONSULTATIVE BODIES.

[no value]
HERBERT SPENCER
TWO parts of the primitive triune political structure have, in the last two chapters, been dealt with separately; or, to speak strictly, the first has been considered as independent of the second, and again, the second as independent of the first: incidentally noting its relations to the third.

SIR JOHN LUBBOCK
IN a very large number of cases the diffusion of seeds is effected by animals. To this class belong the fruits and berries. In them an outer fleshy portion becomes pulpy, and generally sweet, inclosing the seeds. It is remarkable that such fruits, in order, doubtless, to attract animals, are, like flowers, brightly colored—as, for instance, the cherry, currant, apple, peach, plum, strawberry, raspberry, and many others.

HOW TO PREVENT DROWNING.

HENRY MACCORMAC
I WISH to show how drowning might, under ordinary circumstances, be avoided, even in the case of persons otherwise wholly ignorant of what is called the art of swimming. The numerous frightful casualties render every working suggestion of importance, and that which I here offer I venture to think is entirely available.

BENJAMIN VAUGHAN ABBOTT
THE indications seen during the past two years of advance in the law protecting intellectual property are interesting and important. This article will describe some of the more salient steps—the legislation and lately reported decisions—which are of interest to all friends of practical science.

RECENT ADVANCES IN ELECTRIC LIGHTING.

W. H. PREECE
ADVANCES have been made, not so much in electric lighting itself as in the popular favor with which it is regarded. The public is becoming more accustomed to its use, and is acquiring more confidence in it. The result of trials during the last year or two has been to make the defects of the electric light better known.

DEGENERATION.

DR. ANDREW WILSON
IN groups of the animal series, both nearly allied to the crustacean class and far removed from it in structure, equally interesting and often curious examples of degradation may be found. The class of insects and the nearly related group, including the mites, spiders, and scorpions as its representatives, number in their ranks instances of degraded and degenerate forms.

THOMAS D. SPENCER
THERE seems to be no subject from which the mind so instinctively shrinks, few thoughts more repellent to the soul, and no dread vision of the night, howsoever fantastic it be, that presents to the imagination so formidable an aspect as that of death.

ALDEN B. HUET
THE recent consolidation of competing lines of telegraph into one gigantic corporation, and the consequent agitation of the question of Government control by the public press, Boards of Trade, and in Congress, make an inquiry into the subject of postal telegraphs, at the present time, of unusual interest.

THE name of Dr. CHARLES T. JACKSON deserves to be awarded a prominent place in the annals of American science. It is closely associated with the earlier geological investigations in the United States and the British Provinces, and with the initiation of discoveries which have contributed immensely to the increase of the economical resources of the world and to the amelioration of the pains of suffering men.

A CHANGE isgradually coming over the meaning of the word science, or, rather, there is a growing appreciation of its true meaning, which is of great significance. In the newspaper column of “Science” we have a list of results of late experiments of all kinds.

PROFESSOR ROSENTHAL has well conformed to the theory of the “International Scientific Series” in the preparation of this work. It was designed to consist of monographs on special subjects, and not of complete scientific treatises. In this way particular subjects may be more fully expounded than they are in the text-books, while yet the form of publication is popular and convenient.

PROFESSOR FARLOW has, at the request of the United States Fish Commission, investigated the cause of the red color which sometimes appears on dried codfish during hot weather, in connection with which it has been noticed that the fish affected by it decayed with comparative quickness.
