Are You Healthy?, H. Earl Rath Nov 1931

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 Nov 1931

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 Nov 1931

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 Nov 1931

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 Nov 1931

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.

First Aid In The Laboratory, O. B. Read Oct 1931

First Aid In The Laboratory, O. B. Read

Science Bulletin

From the nature of the work carried on in the laboratory one can not always control the results obtained. Accidents are liable to occur at any time. They may arise from many causes among which are incorrect reading of experiments by students, carelessness in obtaining material, defective apparatus, and poor manipulation. The kind of accidents occurring frequently are cuts by broken glass; burns caused by fires, acids, and alkalies; explosions; injuries by breathing poisonous gases; and fainting.

Permanent Achievements Of Science, W. H. Kadesch Oct 1931

Permanent Achievements Of Science, W. H. Kadesch

Science Bulletin

A very delightful man whom I once knew often said that he was deeply grateful to science for all its invaluable gifts to humanity, but that he would have more confidence in scientists if only they would change their minds less frequently. His indictment of science for its instability was a long one, and took a wide range.

Vitalizing Science Teaching, E. J. Cable Oct 1931

Vitalizing Science Teaching, E. J. Cable

Science Bulletin

Scientific problems are not generally discovered by those who sit and idly dream of ease and pleasure, but are found by those who walk through nature with eyes open and all the senses awake to the myriad question marks that are encountered at every turn of the road. Every boy and girl may acquire the scientific turn of mind without the use of a laboratory fitted with expensive apparatus, although all great scientists do their most valuable research in such laboratories. What the science teacher of our public schools needs to do is to direct young life to be always …

Narcotics, H. E. Rath Oct 1931

Narcotics, H. E. Rath

Science Bulletin

The law requires that the nature and effects of both stimulants and narcotics be taught in the public schools. A short time ago the writer asked a dozen college students to describe the nature of the effects of narcotics, and to give the extent of their use. The replies were all much alike. All seemed to have a hazy idea that narcotics put a person into a stupor and that while in this condition the addict dreamed rosy dreams and had a pleasant time generally. Likewise most of the dozen seemed to have the impression that the use of narcotics …

Why Biology?: Editorial Oct 1931

Why Biology?: Editorial

Science Bulletin

Recently, a yoting woman of strong antivivisectionist convictions entered the office of a professor of biology and asked if she might buy some cats which he was keeping for dissection. Upon his refusal of her request - for cats have a way of becoming scarce when wanted for anatomical purposes - she said caustically: "You biologists are regular butchers. Unless one is going to be a doctor or a teacher of biology, what good can it possibly do to know the insides of a cat'?"

Further Observations On The Golden Digger, Roy L. Abbott Sep 1931

Further Observations On The Golden Digger, Roy L. Abbott

Science Bulletin

In two previous numbers of this journal, I have already given some of the results of my studies on the habits, instincts, and intelligence of the Golden Digger wasp. During the past summer I have again studied this wasp, but will give here only a few observations, reserving the rest for a more extended paper.

Science Clubs In High School, C. W. Lantz Sep 1931

Science Clubs In High School, C. W. Lantz

Science Bulletin

The high school has placed a great deal of emphasis on certain extracurricular activities such as athletics, debating, dramatics, etc., but very little attention has been given to any extra-curricular activities in science. Since science does play such an important place in our lives, it seems desirable to consider the possibilities of some extra-curricular activities in high school science. The high school science club offers such an opportunity.

General Science, L. Begeman Sep 1931

General Science, L. Begeman

Science Bulletin

What is General Science? It is wholly an environmental study-not merely one's natural environment but more particularly his man-made environment. In this day and age three-fourths of a man's existence is spent in an environment of invention whether it be in the home or on the street.

The Plight Of The Biologist: Editorial

Science Bulletin

This is indeed an age of science! For the past three hundred years, man has wooed the Goddess of Nature and so ardent has been his wooing, like Sampson of old, she has finally told him her secrets of power.

The Story Of Steve, And Others, Roy L. Abbott Sep 1931

The Story Of Steve, And Others, Roy L. Abbott

Science Bulletin

Steve was a Leopard frog. I say "was" because he long since vanished into the maw of a snapping turtle, and would straightway have been transformed into a part of that twenty-pound bundle of ferocity, had not said turtle been thrown into a furnace by an irate janitor who was fond of Steve but disliked the snapper. Hence, the end of Steve was the occasion for this story of frogs in general and Steve in particular.

Torrid, Temperate And Frigid, Misleading Terms In Geography, Alison E. Aitchison May 1931

Torrid, Temperate And Frigid, Misleading Terms In Geography, Alison E. Aitchison

Science Bulletin

In the March, 1930, issue of the Science Bulletin there was published an article under the caption “Misleading Terms in Geography''. After a discussion of certain terms which had found their way into the science before the days of extended and careful exploration the authors presented an investigation which was being carried on and asked the help of Bulletin readers in furthering it. Since many of the readers of the Bulletin are new and many more have probably forgotten the article it might be well to re-state the problem.

Life In The Biology Laboratory, E. G. Brockman May 1931

Life In The Biology Laboratory, E. G. Brockman

Science Bulletin

Shortly before our class in 10th grade biology was formed, I started preparing a balanced aquarium for the laboratory. In it we have about a dozen small gold fish, several snails, two tad-poles, and a good growth of moss. This aquarium has provided us a great deal of pleasure, as well as many illustrations of life itself.
