Stress Pertinent Facts In Health Teaching, Belva W. Swalwell

Science Bulletin

In the past, much of the health information which high school pupils acquired was handed down to them traditionally. They listened to what their elders had to say and seldom questioned the validity of it. Assertions to the effect that a buckeye carried in one's pocket would prevent rheumatism; that a piece of salt fat pork bound about the neck would counteract diphtheria; or that some malodorous substances would, if breathed, ward off certain communicable diseases were considered as truths and were passed on to the next generation. Since health is now taught in our high schools by teachers adequately …

Measurement Of The Quality Of Water, Jack J. Hinman Jr.

Proceedings of the Iowa Academy of Science

If the problem of the measurement of the quality of water were as simple as it was once held in the judicial opinion of the Mississippi jurist Doctor Mason tells about, (1) there would not be the slightest excuse for this paper. It was the opinion of the court that any ordinary mortal could judge for himself whether or not a water was satisfactory for drinking purposes.

A New Instrument For The Determination Of Young’S Modulus, T. G. Mehlin

Proceedings of the Iowa Academy of Science

The apparatus used for the determination of Young's modulus in the elementary laboratory at Drake has been the vertical suspended wire type, in which the sample under test is loaded and readings taken directly by means of a vernier attached to the wire. Although the readings are accurate to one one-hundredth of a centimeter, the scale cannot be conveniently read, the measurement of the length of the wire necessitates the use of a ladder, and the heavy weights are not easily handled. It is hoped that this new instrument will facilitate the experiment, although it is recognized that the weight …

The Dark Ring Nebula In Cygnus, D. W. Morehouse

Proceedings of the Iowa Academy of Science

Since my report on the Dark Ring Nebula in Cygnus,¹ I have received the following communication from Dr. R. H. Curtiss, Acting Director of the Detroit Observatory of the University of Michigan: "Your article in the February Popular Astronomy on a dark ring nebula in Cygnus has led me to look up an excellent slide which we have of that region made from a photograph secured with the 6-inch Willard Lens on October 5, 1893, at Lick Observatory. The dark elliptical ring stands out very beautifully on this slide. I think anyone would notice it but would be strongly …

Iowa Plant Notes, Ii, R. I. Cratty

Proceedings of the Iowa Academy of Science

Since issuing No.1 of my paper on the above subject¹ quite a number of interesting plants, many of them new to the state, have been added to the State College Herbarium, which it is desired to notice at this time. As might be expected, many of them are introduced plants, some of which may not remain with us long, while others will undoubtedly become permanent additions to our flora.

The Address Of The President - The Ministry Of Science, R. I. Cratty

Proceedings of the Iowa Academy of Science

We are living in a very progressive age - one which when compared with that of our forebears, is filled with advantages for our welfare and enjoyment that challenges the attention of every thoughtful person. That knowledge is power was never a more self-evident truth than it is today, and science, which is simply classified knowledge, is every day coming more closely in touch with human lives, and ministers to us in innumerable ways undreamed of a century ago. Just how great our debt is for all this it is difficult to say. Captain Roald Amundson, that modern Viking whom …

The Action Of An Orifice In An Acoustic Conduit And A Means Of Determing The Effect Of Viscosity, G. W. Stewart

Proceedings of the Iowa Academy of Science

It was shown in a previous communication that the transmission through an acoustic conduit could be computed if the components of the impedance of the branch line were known. In the case of the orifice when viscosity is considered the following are the values of the two components.

Our Native Plants, L. H. Pammel

Proceedings of the Iowa Academy of Science

The following articles are reprinted from several numbers of The Iowa Farmer and Horticulturist of 1853. This magazine was published in Burlington and Fairfield. The articles are contributed by Dr. L. H. Pammel. In your first number you give directions for preparing the garden, and sowing annual, biennial, and perennial seeds. It may not be generally known by your readers and our citizens that as beautiful plants are native to our woods and prairies, as can be found in any portion of the globe; and that they can be as easily and safely transplanted during the months of April and …

The Action Of Cylindrical Tubes In Branch Acoustic Lines, G. W. Stewart

Proceedings of the Iowa Academy of Science

Quincke's tube has long been known. A theoretical and experimental study of its action is herewith reported. Also the formulas for an open tube as well as a closed tube have been derived. The experimental results show unmistakable evidence of the viscosity. The selective property of Quincke's tube is ascertained both experimentally and theoretically for the first time.

The Position Of The Vibrating Source In The Kundt's Tube Experiment, G. W. Stewart

Proceedings of the Iowa Academy of Science

Various textbooks are not in agreement as to whether the vibrating piston is at a node or "near a node." The theory shows that it is strictly at a node. The misstatement in regard to the location of the piston has probably been caused by a misunderstanding of the word "node.” The piston is one-half wave-length from the nearest node and yet it is strictly not a point of rest.

Iodine, A Factor In Feeding Young Growing Swine, John M. Evvard, C. C. Culbertson

Proceedings of the Iowa Academy of Science

Iodine is now generally believed to be absolutely essential for the proper growth and development of the mammalian organism, and its use in animal feeding is becoming more and more general, particularly in goitrous regions.

Lilium Michiganense Farw. In Iowa, Wier R. Mills

Proceedings of the Iowa Academy of Science

With Lilium philadelphicum or the variety andinum this paper has nothing to do. We are concerned with the problem presented in an attempt to classify the wild lily of Iowa which in the past was referred to Lilium superbum by many botanists, and by others to Lilium canadense. In the herbarium at Iowa State College are specimens of lilies sent from different sections of Iowa and labeled Lilium superbum and Lilium canadense by those collecting the specimens. Mr. Cratty, the curator of the herbarium, kindly permitted the writer to examine these specimens and it was found that they were evidently …

The Address Of The President - A Century Of Botany In Iowa, L. H. Pammel

Proceedings of the Iowa Academy of Science

A Century of Botany-It is certainly a pleasure to greet you here on this occasion, especially so, because of the nature of the honorable work performed by the scientists of the State of Iowa. It is customary for the retiring president to deliver an address of some kind. In looking over topics which have been chosen by various retiring presidents I find such titles as "Local Problems in Science," "What We Have Been Doing," "The Academy and the People," "Science of One Hundred Years Ago," "Some Problems of Heredity and Evolution," "Two Centuries of North American Lichenology," "Botany in Its …

Contributions To Knowledge By Gustavus Detlef Hinrichs, M.D., Ll.D. (Paper Presented At The Thirty-Eighth Annual Meeting Of The Iowa Academy Of Science), Charles Keyes

Proceedings of the Iowa Academy of Science

As an original organizer and charter member of the Iowa Academy of Sciences, that society which is the parent of our present Academy, the latter holds with peculiar attachment the memory of the late Dr. Gustavus Hinrichs, who is, for more than a quarter of a century, also identified with the faculty of our State University as one of its most distinguished members. He further organizes and conducts for 15 years our State Weather Service, the first of the kind to be inaugurated in this country. A brief life-sketch of this gifted man appears in our Proceedings of last year, …

Iowa Plant Notes, R. I. Cratty

Proceedings of the Iowa Academy of Science

Recently quite a number of plants new to the State or noteworthy for other reasons, have come under the writer's observation, and it seems well at this time to place these on record. For many years after the settlement of the State the introduction of exotic species was comparatively slow, and was largely confined to those grasses and weeds which were introduced in grain seed, but of late years we are rapidly approaching the condition of the floras found in the Atlantic States where an astonishing number of plants have been introduced, largely of European origin. With us, too, the …

The Structure Of Some Nectar Glands Of Iowa Honey Plants, William S. Cook

Proceedings of the Iowa Academy of Science

The anatomical study of nectar glands was taken up at the suggestion of Dr. L. H. Pammel, who for many years has been interested in honey plants and their economic importance in Iowa. The structure of nectar glands has not received much attention from the present day botanist. He takes for granted that they are present; but that is about as far as he goes. Older botanists of the eighteenth century were much interested in the subject of nectar glands. Glands of many plants were studied thoroughly, that is as thoroughly as could be done with the equipment they possessed. …

Iowa Microlepidoptera, A. W. Lindsey

Proceedings of the Iowa Academy of Science

After writing my last paper on the Lepidoptera of Iowa, viz., "Some Iowa Records of Lepidoptera," I still had in my possession a considerable number of specimens of Tineoidea and all of the Phycitinae which I had taken in the state. I attempted to work up this material during my last few months as curator of the Barnes collection at Decatur, Illinois, and succeeded with most of the Tineoidea. The subfamily Phycitinae of the Pyralidae is in such great need of careful revision that I feel safer in omitting it entirely at present, though I have identified a few species …

The Founders Of The Art Of Plant Breeding, Fred C. Werkenthin

Proceedings of the Iowa Academy of Science

The paper by Prof. Werkenthin on History of Plant Breeding was one of the assigned topics in the course given at Iowa State College on the History of Botany. The subject matter is so admirably treated that it has seemed wise to publish this as a posthumous paper. It was the last paper prepared by him, finished only a few weeks before he was taken sick.

Studies Of Yeast V - Is Bios A Single Substance, Ellis I. Fulmer, V. E. Nelson

Proceedings of the Iowa Academy of Science

In previous communication (Journal of Biological Chemistry, March, 1922) Fulmer and Nelson showed that the water extract of alfalfa is much richer in the yeast growth stimulant, Bois, than is the 95 per cent alcoholic extract of the same material. In the work here described two extracts were prepared as follows from alfalfa which had been previously extracted with ether. Extract A was an extract by long extraction with absolute alcohol. Extract B was an extract prepared by long extraction of the absolute-alcohol-extracted material with water. Both extracts showed optimum concentrations for maximum stimulation and were about equally potent. Combinations …
