The Distribution Of Alcohol In The Tissues Of The Rat, V. B. Fish, V. E. Nelson
The Distribution Of Alcohol In The Tissues Of The Rat, V. B. Fish, V. E. Nelson
Proceedings of the Iowa Academy of Science
In order to determine the distribution of alcohol in the tissues, we have devised a method which is quite simple and accurate. The animal is killed and the tissues removed as rapidly as possible. The tissues are placed in weighed 150 ml. extraction flasks immersed in solid carbon dioxide. The flasks and tissues are weighed and the tissues covered with a solution of picric and tartaric acids. The samples are then placed in a refrigerator until the analysis can be made.

An Apparatus For The Study Of The Kinetics Of Thermal Decompositions, R. B. Anderson, H. H. Rowley, R. F. Makens
Proceedings of the Iowa Academy of Science
For kinetic studies accurate control of the temperature of the reaction flask is required. The reaction flask was placed in a furnace which was constructed in a large metal container A. Forty-four turns of #22 nichrome wire were wound about a 12"x4½" refractory cement core. To insure uniform distribution of heat, the flask was immersed in a bath of molten tin.

Ocular Photography As A Scientific Approach To The Study Of Art, Herman F. Brandt
Proceedings of the Iowa Academy of Science
Regardless of how we look at art we project into the art object the response as expressed by individuals. Whether we judge design or color we evaluate it in the light of our own response to it. Since this is the general procedure in arriving at a decision in judging paintings or statuary we need to make inquiry as to just what behavior is involved in making such a choice.
An Anomalous Chick Embryo Pulsating As A Heart, William M. Goldsmith, Dayrle N. Crabb
An Anomalous Chick Embryo Pulsating As A Heart, William M. Goldsmith, Dayrle N. Crabb
Proceedings of the Iowa Academy of Science
During the regular laboratory work in embryological technique, the finding of anomalous chick embryos is so common that little interest is attracted. However, when one student reported the rhythmic beating of a solitary chick heart apparently without the accompanying chick, special interest was stimulated. This strange pulsating bit of protoplasm was noted in an egg of about 50 hours incubation. It was transferred to warm, normal physiological saline solution and observed for fifteen minutes. The beating was not unlike that of a normal chick heart of corresponding age. In order to assure a good fixation, the specimen was removed from …
Vanishing Original Prairie Area In Cedar Rapids, Iowa, George R. Browne
Vanishing Original Prairie Area In Cedar Rapids, Iowa, George R. Browne
Proceedings of the Iowa Academy of Science
This report is the result of a study during the years 1938-41. The flowering plants as well as the other vegetation are treated and the object is to establish some record of the flora on this original prairie area before the region was completely destroyed by the extensive home building program which is now in progress. The natural prairie is located in the Maplewood addition. It is approximately 40 acres in area.

Some Notes On The Fungi Of Henry County, Marvin Tulk
Some Notes On The Fungi Of Henry County, Marvin Tulk
Proceedings of the Iowa Academy of Science
For more than a year the writer has been giving special attention to the species of fleshy fungi that could be found on the frequent collecting trips. There is no thought of posing as an expert, but it is hoped that some of these field observations will prove of interest and value. Our region includes a widely diverse habitat, Skunk River and Big Creek are both within easy reach and furnish deep damp woods, rough hillsides and occasional small water soaked areas. In many parts level farm land predominates. The writer's collecting was restricted to the vicinity of Mt. Pleasant, …
A Measurement Of The Magnitude Of The Electrokinetic Current In Liquid Flow Through A Single Capillary, W. G. Eversole, W. W. Boardman
A Measurement Of The Magnitude Of The Electrokinetic Current In Liquid Flow Through A Single Capillary, W. G. Eversole, W. W. Boardman
Proceedings of the Iowa Academy of Science
The potential difference, E, between the two ends of a capillary, through which a steady flow of liquid was maintained, was measured by means of unpolarizable electrodes connected to a potentiometer circuit, and at the same time shunted through a known resistance, R. The value of R was varied from 1 to 98000 megohms. For each value of R there was a corresponding value of E, and a current, I (=E/R), through the resistance. The electrokinetic current, Ie, was obtained by extrapolating the plot of E/R versus R to the limit R=O.

Mme. Caroline Testout: The Grand Dame Of The Roses, Clark D. Paris, T. J. Maney
Proceedings of the Iowa Academy of Science
In all breeding work one finds that certain individuals are outstanding in the production of superior progeny. In animal breeding these individuals form the basis for pedigreed stock. An intensive study on the parentage of rose varieties has revealed that certain roses also have produced more named offspring than others. To obtain this information, it was necessary to make a search through the world's most important literature on the rose. This study resulted in the compilation of an index of about 5,000 rose varieties on which parentage data had been recorded.
A Note On Axis Restoration In A Gymnosperm Tree, Robert B. Wylie
A Note On Axis Restoration In A Gymnosperm Tree, Robert B. Wylie
Proceedings of the Iowa Academy of Science
Injury to the major axis of a tree with excurrent growth often results in the development of a dwarfed or unsymmetrical crown. In the case of certain gymnosperms the lost apical shoot can be restored by bending upward one of the adjacent lateral branches and fastening it in upright position. In this way it may be induced to develop into a radical, lead shoot and dominate the further growth of the tree. While this practice is fairly well known it should occasionally be brought to the attention of the general public. The following paragraphs record another instance of the successful …

Histological Responses Of Stock (Matthiola Incana) Seedlings Treated With B-Indolyl Acetic Acid, F. M. Turrell, L. C. Bauguess
Histological Responses Of Stock (Matthiola Incana) Seedlings Treated With B-Indolyl Acetic Acid, F. M. Turrell, L. C. Bauguess
Proceedings of the Iowa Academy of Science
Kögl, Haagen Smit and Erxleben (1934) confirmed the finding of Salkowski and Salkowski in 1895 that urine contained B-indolyl acid, and found that this substance accounted for a portion of the activity of urine in promoting the growth of plants not accounted for by auxcntriolic acid and auxenolonic acid. Majima and Hoshino (1924) had already developed a method for the synthesis of B-indolyl-acetic acid so that it became evident to the authors that sufficient amounts of B-indolyl acetic could be made readily available for plant growth hormone studies.
The Genus Lysimachia In Iowa, George J. Goodman, P. J. Leyendecker
The Genus Lysimachia In Iowa, George J. Goodman, P. J. Leyendecker
Proceedings of the Iowa Academy of Science
Many botanists, including students who have studied the Primulaceae from a world viewpoint, consider Lysimachia and Steironema as one genus. Lysimachia is here considered in this broad sense. Authentic material of five species and one variety from North Dakota, described by Greene and by Lunell, has not been seen, but any Iowa specimens examined that seemed to possibly agree with the original descriptions of the Dakota plants did not appear to be sufficiently distinct from the earlier described species, listed below, to warrant separating them.

Formation And Properties Of Some Uretediones, Harlan B. Freyermuth, L. Chas. Raiford
Proceedings of the Iowa Academy of Science
ofmann (Ber., 4, 246. 1871.) found that triethylphosphine served as a catalyst to cause the polymerization of phenyl isocyanate to a dimer which he designated as diphenyl diisocyanate. Staudinger ("Die Ketene", Enke, Stuttgart, 1912, p. 126.) regarded this product as a four atomic ring derivative. It has now been found that triethylphosphine polymerizes a number of substituted phenylisocyanates, such as λ- and β-naphthyl isocyanates, and p-xenyl isocyanate. These products which have more recently been listed as derivatives of uretedione, react with aliphatic amines to produce substituted biurets.

Some New Light On The Old Problem Of Learning In Physics, C. J. Lapp
Some New Light On The Old Problem Of Learning In Physics, C. J. Lapp
Proceedings of the Iowa Academy of Science
Educational psychologists have given significant facts concerning human forgetting. To combat forgetting an experimental research program was organized and carried out in the Summer of 1941 in the Pennsylvania Summer EDT in physics. Devices used to offset forgetting and produce achievement were highly successful.

The Prediction Of Driving Ability From Laboratory Measures And Experience Indices From A Systematized Interview, Leonard E. Shupe, A. R. Lauer
Proceedings of the Iowa Academy of Science
The U. S. Army is faced with the problem of selecting drivers for immediate and active service in the motorized units. Although the youth of America are mechanically inclined, intimate acquaintance with the operation and care of motor vehicles is not at all universal. Many have driven but slightly, and usually have had experience with passenger type vehicles only.
Inheritance Of Pitted Ear Through Six Generations, George C. Huff, Winifred Brillhart
Inheritance Of Pitted Ear Through Six Generations, George C. Huff, Winifred Brillhart
Proceedings of the Iowa Academy of Science
Several papers have appeared in recent years on the inheritance of ear pit (Fistula auris congenita), but despite the accumulation of data over a long period of years, the problem of the mechanism involved in hereditary transmission of ear pit is not completely satisfactory.
Heritable Characters In Maize: "Accessory Blade", George F. Sprague, J. E. Sass
Heritable Characters In Maize: "Accessory Blade", George F. Sprague, J. E. Sass
Proceedings of the Iowa Academy of Science
A mutant character in maize brings about the formation of ridge and blade-like outgrowths on the surfaces of leaves. These accessory laminae, which are present on the partially developed leaves in the dormant embryo, arise by re-activation of vertical zones on the immature leaf.
Typhula Juncea In Iowa, Mary Louise Grumbein
Typhula Juncea In Iowa, Mary Louise Grumbein
Proceedings of the Iowa Academy of Science
So far as is known, no species of Typhula has heretofore been reported from Iowa. It is of interest, therefore, to record the occurrence of a striking species of this genus. On the rainy afternoon of October 4, 1941, it was discovered fruiting in great abundance on fallen oak leaves in a wooded ravine between North Liberty and Lake Macbride. The pale yellow clubs, 10-12 cm. tall, were developing over an area a hundred feet or more in length and twenty or thirty feet in width in such profusion that in places they suggested patches of yellow grass blades.
The Liverworts Of Iowa, Henry S. Conard
The Liverworts Of Iowa, Henry S. Conard
Proceedings of the Iowa Academy of Science
The collections of moss plants from the State of Iowa have been examined to such an extent that we feel warranted in making a statement of our present knowledge of the species of liverworts and their distribution in the State. While many collections of true mosses have not yet been examined, all of the packets known to contain liverworts have been studied, so far as known to us. It seems unlikely that any additional species will appear in the collections already made. Probably a few extensions of range will be found. This report will indicate the lacunae in our knowledge …

Changes In The Attitudes Of College Students In Religion And Politics, George R. Pullman, Earle E. Emme
Proceedings of the Iowa Academy of Science
It is the purpose of this paper to determine whether or not the attitudes of college students change in the fields of Religion and Politics as a result of having taken courses pertaining thereto or as a result of the college experience as a whole. SOURCES OF INFORMATION: Information was obtained through a summarization of research on the subject and by an investigation of recent psychological magazines and bulletins.
Qualitative Microanalysis Of Non-Ferrous Metals, George W. Brown, Lothrop Smith
Qualitative Microanalysis Of Non-Ferrous Metals, George W. Brown, Lothrop Smith
Proceedings of the Iowa Academy of Science
During summer vacations, part of my school expense was earned as a purchaser of non-ferrous scrap metal for a small Chicago smelter. In such purchasing, it is very necessary to know something of the general composition of the metal. For example, in buying soldered articles, it is of vital importance to know whether the solder is high in tin or lead, and whether it contains antimony or bismuth. Other purchasers to whom I have talked have reported the same difficulty.

The interpretation of seismograms presents numerous problems and offers unlimited opportunities in the field of research. To the geologist it offers means of studying the interior structure of the earth, and familiarity with the unstable regions of the earth.
Survey Courses In Mathematics, O. C. Kreider
Survey Courses In Mathematics, O. C. Kreider
Proceedings of the Iowa Academy of Science
Many ideas have invaded mathematical discussions in recent times and have pointed out the need for survey courses in mathematics. By some, the people who presented these ideas have been considered fifth columnists to entice us away from our national traditional courses in mathematics. In our present crisis we find our national educational domain disarmed and at a disadvantage in the mathematical field.
