The Prolificness Of Some Common Plants, H. E. Jaques

Proceedings of the Iowa Academy of Science

The way Nature's creatures maintain their uniform balance when varying so widely in the number of offspring produced, is one of the most interesting problems of the Biologist. This paper gives the results of some computations made to determine the number of seeds produced by some of our common plants.

Catalysts And Activated Magnesium In The Preparation Of Grignard Reagents, Henry Gilman, J. Merriam Peterson

Proceedings of the Iowa Academy of Science

Many RX compounds enter sluggishly into reaction with magnesium in the preparation of organomagnesium halides. Furthermore, it is actually impossible to form RMgX compounds from some RX compounds. Accordingly, a study is in progress on catalysts and activated magnesium in order to extend the preparation of Grignard reagents. The results so far obtained show that when an alloy containing 121% copper and the remainder magnesium is heated in an evacuated tube at 200° for one hour with about one-half its weight of iodine, the activated alloy thus obtained is superior to that described by Baeyer and used so extensively at …

Water-Table Of The Loess, Charles Keyes

Proceedings of the Iowa Academy of Science

McGee, Calvin, Bain, Todd, and other Iowa geologists, repeatedly direct attention to the occurrence of an "iron streak" in many loess sections. No offer is made of an explanation of its possible origin. In recent, extensive, street-grading operations in Des Moines, clue is given to this phenomenon. It does not reveal itself usually in small exposures or in building excavations. But in long hill-side grades it is found to be the line of the old water-table, the level of phreatic waters, and, as shown by filled-up wells of the early settlers, to be the depth to which they had to …

Dinosaur Egg Remains From Mongolia, A. O. Thomas

Proceedings of the Iowa Academy of Science

There was recently added to the paleontological collections at the University several fragments of shells of eggs of the dinosaur Protoceratops andrewsi. They come from the Dja-doch-ta beds of Cretaceous age at Shabarahk Usu, Outer Mongolia, China. The bits of eggshells and a piece of the skull with teeth in place and a part of the frill were collected and presented by Dr. Ralph W. Chaney a member of the Third Asiatic Expedition. (See NATURAL HISTORY, volume xxv, Nov.-Dec. number, 1925, pages 622, 623). The eggshell fragments are over one millimeter thick, are smooth on the inside and are marked …

Do Students Grades In Physics Correlate With Grades In Other Subjects?, Alice Neff

Proceedings of the Iowa Academy of Science

If we compare students' grades in physics with grades in other subjects, we find figures which are worth some notice as they reveal interesting facts. Using the grades of 87 of Drake University College physics students, I find that their average grade in other subjects and their physics grades give a correlation of 90%. The means of both the physics and average grade are almost a C+.

The Status Of The Psychogalvanic Reflex In Psychology, Nancy Bayley

Proceedings of the Iowa Academy of Science

Experimental studies of the emotions are comparatively recent undertakings. Most investigations have been done by means of the "method of expression," on the basis of a physical measurement of characteristic physiological changes, as breathing or pulse. One of the more promising of these measurements is that of the so-called psychogalvanic reflex. This reflex is a change of electrical conduction through the body which can be measured by means of a galvanometer. It occurs under emotional conditions and when an emotion is reported by the subject. This phenomenon was first reported by Feré in 1888 when he found the reflex corresponding …

A Schematic Classification Of General Psychology, Christian A. Ruckmick

Proceedings of the Iowa Academy of Science

The elementary student is usually bewildered by the presentation of technical names which are used to describe the various branches of elementary psychology. Very often he cannot easily distinguish between differences in points of view, methods of approach and fields of activity. In a previously published article an attempt has been made to clarify the situation on the subject of method. The same thing has here been attempted for the subdivisions of psychology.

Predicting Scholastic Success On The Basis Of Informational Data, F. K. Shuttleworth

Proceedings of the Iowa Academy of Science

This paper reports the preliminary results of an attempt to predict scholastic success on the basis of certain informational data. In connection with another investigation all freshmen at the University of Iowa were asked twenty-six questions concerning their high school grades, high school activities, size of graduating class, population of home town, mothers' and fathers' education, certain home influences, etc. The answers to these questions were wholly objective, being made by checking the appropriate answer. These answers were scored and an actual prediction of scholastic success was made.

The Diagnosis Of Character Types By Visual And Auditory Thresholds, Ronald C. Travis

Proceedings of the Iowa Academy of Science

Clinical methods of diagnosis in mental diseases are taking on more scientifically controlled aspects. Especially is this true in the so-called functional neuroses. This study subjected to a certain type of measurement two groups of abnormal individuals, the schizophrenic group and the psychoneurotic. The classical clinical distinction between these two groups is that the schizophrenic is characterized by negativism, restriction of reactions, seclusiveness, emotional and mental deterioration and an introverted viewpoint; while the behavior of the psychoneurotic is characterized by suggestibility, expansion of reactions, overtness, and a correspondence between emotions, thoughts, acts and external conditions.

Trapping And Banding Birds At Iowa City During 1925, Dayton Stoner

Proceedings of the Iowa Academy of Science

The present brief account is intended as a progress report on the status of the bird trapping station located in the back yard at my home in Iowa City. This station, consisting of two government sparrow traps, was established in 1920 and has been in almost constant operation since that time. An "Everset" trap was added to the complement of traps in 1925.

The Taxonomic Value Of Style Color In The Genus Antennaria, Helen Nicholson

Proceedings of the Iowa Academy of Science

In the genus Antennaria, commonly known as Indian Tobacco, the color of the style arms (usually red or white) is used as a distinctive character in the descriptions of many species, and is emphasized in at least one key. My study of the genus as it occurs in Iowa convinces me that this character is too variable to have any diagnostic value.

The Effect Of Pressure On Chemical Reaction, F. E. Brown

Proceedings of the Iowa Academy of Science

One of nature’s most pervasive characteristics is conservatism, but her conservatism is tempered with adaptability. She yields to any force however small, but yields as slowly and with as little inconvenience to herself as possible. At the same time, every device which uses up the energy producing the change is brought into play. For instance, when heat is applied to a system, the most careful insulation cannot prevent the dispersal of part of it by conduction, convection and radiation. Some of it is used in the work done by expansion. Every possible chemical reaction and physical change which absorbs heat …

A Valence-Name-Formula-Solubility Chart, G. N. Quam

Proceedings of the Iowa Academy of Science

The chart includes the names and symbols of all the common radicals used in general chemistry courses arranged in a definite order according to valence. Each small rectangular space formed by horizontal and vertical lines including a positive and negative radical represents a compound and contains a symbol representing the solubility in grams per 100 grams of water at 18 degrees centigrade. Each large rectangular space represents compounds having a common type formula. The primary purpose of the chart is to aid the student in acquiring speedily a working knowledge of valence, radicals and formula writing.

Terranal Affinities Of Iowa Chalks, Charles Keyes

Proceedings of the Iowa Academy of Science

With the larger perspective of the Cretaceous formations recently opened out to the west of us, between the Missouri River and the Rocky Mountains, the depositional relationships of our Iowa terranes take on new aspect. Above the basal Dakota sandstone, so well represented in our state, all of the great black-shale sequence, including the Benton, Pierre, Masuk and other similar divisions, is now regarded as a single provincial deposit, comprised under the title of Assiniboian series. Into this great body of black-shales extend from the shoreward margins huge wedges of terriginous clastics; while from our side, the seaward side,· appear …

Thermoelectric Effect In Single Crystal Zinc Wires, E. G. Linder

Proceedings of the Iowa Academy of Science

The work reported is a continuation of measurements published in the Physical Review for October, 1925. The thermol e.m.f. of the zinc crystals against copper has been measured from -182°C to 480°C for crystals having orientations from about 10° to 90°. The relation between thermoelectric power and temperature is definitely not linear, but may he represented fairly well by a second degree equation. The nature of the effect in the neighborhood of the melting point will be discussed.

A New Type Of Electromagnetic Wave Meter, Winfield Salisbury

Proceedings of the Iowa Academy of Science

A high degree of accuracy and sensitivity are obtained by using a combination of a two element vacuum tube and direct current galvenometer, which measures the voltage across the condenser in the resonant circuit instead of the current in the inductance as is the common practice. The small amount of energy necessary to operate this indicator makes possible a very sharp resonance peak. Its sensitivity allows it to be operated far enough from the source of the waves that it does not affect their length. A new method of locating nodes on Lecher's wires makes possible whatever accuracy can be …

A Modification Of Lees' Method For The Determination Of The Heat Conductivity Of A Poor Heat Conductor, Paul C. Oversheet

Proceedings of the Iowa Academy of Science

Lees' Method is described at length in the Phil. Trons. An 1898, vol. 191, also in a general way in Poynting and Thompson's "Heat" and Watson's "Textbook of Physics." The modified method is described in detail in "The Measurement of the Heat Conductivity of Sulfur and a Sulfur-Coke Mixture," Physics Thesis by Paul C. Overstreet, State University of Iowa, 1925. This method consists of the measuring of the temperatures of a hot copper disk, U, on one side of a poor heat conducting disk, S, and that of a cooler disk, M, on the other side of S, after …

Optical Constants Of Bismuth Crystals In The Ultra-Violet, Florence E. Dix

Proceedings of the Iowa Academy of Science

Index of refraction and extinction index for light reflected from a cleavage surface of a bismuth crystal have been determined at several wavelengths in the ultra-violet. The crystelliptometer of Weld is being used. A comparison in the overlapping region with the measurements of Rowse will be given.

The Iowa State College Reasoning Test, Thomas F. Vance

Proceedings of the Iowa Academy of Science

In order to arrive at the point of this paper on the subject, "The Iowa State College Reasoning Test" it is necessary to describe briefly the other tests of which it is one in the series. The psychological test which has been given this year to the Freshman class of Iowa State College is a modified Alpha. The Alpha was chosen as a basis on which to construct a new form for the reason that it has given consistently higher correlations than it has been possible to secure with any other test. In the modified form, Arithmetic, the Synonym and …

A Preliminary Study Of The Nature Of Finality In Melody, Ruth Updegraff

Proceedings of the Iowa Academy of Science

According to a recognized definition, a melody is a succession of musical sounds which is felt to constitute a unity. The stipulation, sometimes made, that this unity must be aesthetic, is felt to be not only ambiguous, the aesthetic depending to some degree on individual taste, but restricting, in the sense that melodies termed aesthetic by common consent would be few in number. Unity implies, first, an interrelationship, and secondly, coherence and completeness as a whole; that is, relationship and finality. The melody problem is that of discovering how a series of tonal stimuli can excite a feeling of unity.

The Influence Of The Rhetorical Question On Learning, E. O. Finkenbinder, John E. Schalk

Proceedings of the Iowa Academy of Science

Two college classes of 45 students were given two sets of materials, each set presented to one group of students with rhetorical questions inserted and to the other group without rhetorical questions. The average value to learning of the questions inserted was 17%.

Winter Birds Records, 1922 To 1926, In Northwestern Iowa, Chas. J. Spiker

Proceedings of the Iowa Academy of Science

It is the purpose of this paper to connect with a series of papers on winter birds in Northwestern Iowa, started in 1917 by Dr. T. C. Stephens of Morningside College. The observations herein noted were made by the writer during the four winters of his attendance at Morningside College, Sioux City. The records in the main are for Woodbury County; any data obtained outside of Woodbury County are specified when they appear in the paper.

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 M Series Absorption Spectra Of Osmium Iridium And Platinum, R. A. Rogers

Proceedings of the Iowa Academy of Science

Spectrograms have been obtained of all but three of the predicted M series absorption limits of osmium, iridium, and platinum. A vacuum spectrograph of the Siegbahn type was used in this work. The slit of the spectrometer chamber was covered with a very thin celluloid film, smoked over a kerosene flame until sufficiently darkened to keep out the light of the incandescent filament. To make the film, celluloid was dissolved in amyl acetate and thinned until about like molasses. One small drop on the surface of water spread out forming a film two or three inches in diameter. After the …

Notes Of Oxygen Consumption In Turtles Chrysmus Marginata Belli And Chelydra Serpentina Linn, Francis Marsh Baldwin

Proceedings of the Iowa Academy of Science

In an earlier paper read before the Academy, data were given on the comparative ratio of oxygen consumption in certain fishes and other marine forms. These figures were obtained by analysis of samples of water in which the animals had been kept, using the chemical method devised by Winkler. As is customary in such work, the figures of consumption were reduced to the volumetric basis at uniform pressure and temperature and were expressed in cubic centimeters per gram of body weight per hour. There resulted from these studies an interesting comparison in metabolic rate in the different fishes, being greatest …
