General Science, E. J. Cable
Science Bulletin
In our last article we discussed one of the common minerals found on the earth's surface. In this article the writer will attempt two things: first, to describe a few of the common rock-making minerals; and second, to discuss some of the simple ways of distinguishing the common igneous rock found on the earth's surface. The commonest igneous rock-making minerals, besides quartz, are the feldspars, the irons, pyroxene, hornblende, and the micas.
What About Organic Evolution?, C. W. Lantz
What About Organic Evolution?, C. W. Lantz
Science Bulletin
One of the great generalizations of science is the theory of organic evolution. It is, however, very commonly misunderstood by the average person. To many, thanks to such deluded individuals as the late Wiliiam Jennings Bryan, it is a very dangerous doctrine and any one who believes in it is an atheist and must reject the teachings of the Bible. I have had college students ask this question. Is it possible for one to believe in evolution and be a Christian? This question arises only from one who has misconceptions as to the real meaning of evolution and perhaps also …
Motivation In Physics, W. H. Kadesch
Motivation In Physics, W. H. Kadesch
Science Bulletin
In recent years there has been a decided trend in high schools the country over toward general science, and away from the particular sciences, physics, chemistry, biology, etc. The proponents of general science seem convinced that this is due to a better choice of subject matter in their field, and to better methods of presentation. However this may be, it will certainly be well for those of us who have to do with the teaching of the special sciences to subject our own work to critical examination. We should aim to discover our faults of whatever kind, and eliminate them.
Snakes That Do Not Exist, C. W. Lantz
Snakes That Do Not Exist, C. W. Lantz
Science Bulletin
As a boy I was always on the lookout for two kinds of snakes which I never found. These were the so- called hoop snake, and joint snake. According to popular tradition - and the tradition is still with us - the hoop snake was supposed to take his tail into his mouth and go rolling about the country much to the amazement and horror of his human observers.
Disillusionment!: Editorial
Science Bulletin
Who has not felt his very flesh writhe and shrink on reading Hugo's fearful story of Gilliatt's fight with the octopus? The art of the great Frenchman is here superb. He compels the reader to identify himself with his hero. Gilliatt's struggles and emotions are his also. The monster projects itself upon him- its tentacles entwine him, their horrible sucking vacuum cups pull at his flesh; he strains, heaves, grasps at these accursed circling gelatinous bands; they seem to yield, but never actually; they crush, excoriate, scarify - his flesh seems to melt - he is disintegrating-it is death in …
On Snakes Swallowing Their Young, Roy L. Abbott
On Snakes Swallowing Their Young, Roy L. Abbott
Science Bulletin
Do snakes actually swallow their young to protect them and later spew them out again as Dr. Ball states further in his article? Well, I have never seen them do this, and I do not know of any other student of snakes who has. Ditmars, Curator of Reptiles at the New York Zoological Gardens, has never seen anything of this kind, and he daily observes more snakes than the average man does in a lifetime.

Suggestions For The Teaching Collection In Biology, O. R. Clark
Suggestions For The Teaching Collection In Biology, O. R. Clark
Science Bulletin
There is nothing in the Biology course which can take the place of carefully planned and directed field work. The students should be encouraged to observe carefully and accurately for themselves and be given every opportunity to become acquainted with living things in their natural surroundings. The aquarium and terrarium can be made to supply much interesting material for study and should be in the laboratory whenever possible.
Are You Healthy?, H. Earl Rath
Are You Healthy?, H. Earl Rath
Science Bulletin
Most authors of texts on hygiene have presented some sort of an ideal towards which each individual should aim. All of them have merit, but the present article is based largely (with a few modifications) on the eight points of "The Health Ideal" as set forth in the "College Text Book of Hygiene" by Smiley and Gould.
David Starr Jordan: Editorial
Science Bulletin
The subject of this sketch seems to have been fortunate in both conditions, heredity and environment. He developed a huge, vigorous body and a powerful, alert mind, one peculiarly capable of noting and retaining infinite details of color, form, and structure. The fishes, a group characterized by almost unbelievable diversity of form, color-pattern, and habitat, were thus admirably suited to his retentive type of mind, and David Starr Jordan became an ichthyologist, a student of fishes.
Induced Current Electricity, L. Begeman
Induced Current Electricity, L. Begeman
Science Bulletin
In the May Number of the Science Bulletin, the writer gave a brief outline of the historical development of our present knowledge of the magnetic properties of an electric current. In tracing this development from an experimental point of view, a brief statement was made of the contributions of each of the following renowned scientists: Oersted, Arago, Ampere, Faraday and Henry. In this article of the May Number no reference was made to current induction as one of the magnetic effects of an electric current.
The Toll Of The Automobile, Roy L. Abbott
The Toll Of The Automobile, Roy L. Abbott
Science Bulletin
When the telegraph first came into general use in this country thousands of birds, particularly prairie chickens, were killed annually as a result of flying against the tightly stretched wires. On account of its great height, many birds collide with the Washington Monument, and are thus fatally injured; every lighthouse along the coast takes a great toll of birds during the year. The railroads destroy many animals also, but the automobile murders more wild animals than all the above-mentioned things combined. In the destruction of our wild fauna, it is next in importance to the rifle and shotgun. The Isaac …
Phantom Ringnecks, Roy L. Abbott
Phantom Ringnecks, Roy L. Abbott
Science Bulletin
Now the ring-necked pheasant is a big bird; he is about the size of a well-fledged leghorn rooster, weighs perhaps three and one-half to four pounds, and, including his long tail feathers, stretches easily two feet or more in length. Moreover, Nature fairly outdid herself in beautifying the ringneck; he is a perfectly amazing combination of green and red, of white and gold and bronze. His mate, on the other hand, is about the color of a prairie chicken, severely plain, modest and retiring.
