The Peripheral Distribution Of The Cranial Nerves Of Necturus Maculatus, H. W. Norris, Margaret Buckley

Proceedings of the Iowa Academy of Science

Although Necturus is so commonly used in laboratory courses of vertebrate dissection there have been few attempts made to give a systematic account of its cranial nerves. Laboratory guides and outlines still adhere to an antiquated nomenclature in reference to the nervous system of Necturus, for which procedure there is little excuse in the light of the work that has been done already on the nervous systems of other Urodela.

The Action Of Epinephrin Upon The Muscle Tissue Of The Vein, J. T. M'Clintock

Proceedings of the Iowa Academy of Science

The physiology of the venous circulation has, in comparison to that of the arterial, received very little consideration. It has been looked upon as a circulation carried on in a system of inert, elastic tubes, carrying the blood back to the heart from the periphery and without much, if any, physiological action on the part of the venous wall in the process. We are in the habit of looking to the heart, the arterial tension and the skeletal muscle action as being the forces driving the blood through the venous system.

Asteroid, 1909, Ja, Seth Nicholson, Alma M. Stotts

Proceedings of the Iowa Academy of Science

The discovery of the minor planets or asteroids has become so general in recent years that the work of following them after their discovery is of great importance. After an orbit has been calculated the asteroid can be identified and a permanent number and name given to it; then it is a known member of our Solar System. The asteroid whose orbit and ephemeris have been computed and are given in this abstract, was discovered by Joel H. Metcalf at Taunton, Mass.

Flowers Of Story County, J. M. Lindly

Proceedings of the Iowa Academy of Science

Noticing that the proceedings of the Iowa Academy of Science do not contain any particular enumeration of the flowers of Story County, the writer is prompted to offer the following list from the herbarium of Vene C. Gambell, who was a student at Ames during the earlier part of the decade of 1880-90. Such a list, perhaps only partial, is thus afforded the academy, and a more permanent and accessible record given the earlier work of one of the brightest young students of science in the history of the state, who, had he been permitted to round out the ordinary …

Pollination Of Clover, L. H. Pammel, Charlotte M. King

Proceedings of the Iowa Academy of Science

It has frequently been stated by scientific investigators that insects are necessary to convey the pollen in cross fertilization of red clover. The opinion is often expressed by clover growers and some popular writers that insects are not necessary to secure pollination of red clover. The following by Henry Wallace is a fair statement of the position taken by quite a number of agricultural writers.

An Ecological Study Of A Prairie Province In Central Iowa, Ada Hayden

Proceedings of the Iowa Academy of Science

This virgin prairie area is mostly of the kame hill, saucer type. One portion of the territory is probably the pre-Wisconsin bed of the Des Moines River whose course was changed by the ice sheet. The region examined in detail is one mile in radius and bordered by a woodland adjacent to Skunk River.

The Flowers Of Myiophyllum Spicatum L., N. D. Knupp

Proceedings of the Iowa Academy of Science

The Myrtales comprise one of the highest orders of the Archichlamydeae. They are characterized by the adhesion of calyx and receptacle, usually epigynous, always cyclic, with a definite number of parts in each whorl. The order is an important tropical one, and furnishes many products of commercial value. More recently the group has attracted widespread attention as it contains the genus Oenothera with which De Vries worked out his mutation theory.

Nitrogen In Rain And Snow, Nicholas Knight

Proceedings of the Iowa Academy of Science

Shutt, Chemical News, December 10, 1909, determined the nitrogen in the rain and snow that fell near Ottawa, Canada, during a portion of the year 1906 and 1907. It occurred to us it might be interesting and profitable to study the precipitations of Mount Vernon, Iowa. The investigation was begun on January 12, 1910, and was continued for one year with the exception of the months of May, June, July and August. These were extremely dry months and we regret very much not to have been able to secure a sample of the heavy rainfall which broke the long drought, …

Problems On The Border Lines Between Geology And The Other Sciences, G. F. Kay

Proceedings of the Iowa Academy of Science

In this paper attention is called to the need of co-operative work among investigators in the different fields of science. Reference is made to several bulletins and papers which have already been published by the chemists of the United States Geological Survey, by the physicists of the geophysical laboratory, and by other scientists, throwing light on many problems in geology which heretofore were obscure. The necessity for further work upon border problems, already under investigation, and upon many other problems which need solution, is emphasized.

Despositional Phases Of Eolation Under The Stimulus Aridity, Charles R. Keyes

Proceedings of the Iowa Academy of Science

It is now a question whether wind-scour under the stimulus of a typically arid climate is not actually the most potent and persistent of the erosive agencies. Under favorable conditions its general efficiency must greatly exceed that of stream-action in normally moist lands. At any rate, erosionally, its world's work is probably surpassed neither by that of hydrasion nor of glaciation.

The Use Of A Ballistic Galvanometer And Pendulum For Measuring Rapidly Fluctuating Resistances, W. H. Clark

Proceedings of the Iowa Academy of Science

The degree of accuracy with which physicists have divided the fundamental units of length and mass, the centimeter and the gram, demands a division equally as accurate of the remaining unit, the unit of time. We are all familiar with Michelson's measurement of the standard meter where a half and a quarter wave length of light was a quantity not to be neglected. Our recent literature describes a balance which will weigh to one millionth of a milligram. When we consider these facts and the added fact that time so often enters into our formulae to the second degree we …

On The Recovery Of The Elastic Properties Of A Platinum Iridium Wire, L. P. Sieg

Proceedings of the Iowa Academy of Science

The writer has at various times discussed the elastic properties of wires made by alloying different percentages of iridium with platinum. In particular this study has been carried on with a 40 per cent alloy. The principal feature of the previous work was a study of the torsional elastic properties of this wire; the wire in these cases being used as the suspension of various torsion pendulums. One of the facts of most importance developed in this investigation was that the period of the pendulum not only depended upon the amplitude (a fact discovered by Guthe) but that the relation …

The Doppler Effect In Electrodless Discharge, Frank F. Almy

Proceedings of the Iowa Academy of Science

It would appear that if the source of luminosity is in motion in the ring electrodeless discharge, that there should be a broadening of the spectral lines when viewed in the line of motion.

The Rank Of Necturus Among The Tailed Amphibians As Indicated By The Distribution Of Its Cranial Nerves, H. W. Norris

Proceedings of the Iowa Academy of Science

That "the Proteidae constitute the most primitive of the Urodeles" (Holmes, 1906) is generally accepted as an established fact. But here and there one finds dissenting opinions from this particular view. Kingsbury (1905) has given some very instructive and suggestive comparisons, chiefly of skeletal features, between Necturus and typical Urodela showing that Necturus and the larval stages of Spelerpes have so many characters in common that the similarities must stand for some degree of close relationship.

Building A Museum, T. Van Hyning

Proceedings of the Iowa Academy of Science

The up-to-date museum is the highest possible type of an educational institution; it supplies the text accompanied by the object. (Object teaching.) All museums should be, in a manner, provincial, i.e., organized to cover a certain territory as a specialty, whether this territory be a single state, several states, the United States, or the whole world. In this connection it should be remembered that almost any single state will produce a much more varied and larger amount of museum material than is commonly supposed. The geology, flora, fauna, prehistoric and civil history of a state, will, in many instances, nearly …

The Development Of The Sympathetic Nervous System In Birds, Albert Kuntz

Proceedings of the Iowa Academy of Science

The present investigation of the development of the sympathetic nervous system in birds was undertaken in order to extend the writer's observations on the histogenesis of the sympathetic nervous system in mammals, and to point out certain morphogenetic differences in the development of the sympathetic system in birds and mammals, with a view to their phylogenetic significance.

A Study In The Determination Of Calcium, George Heise

Proceedings of the Iowa Academy of Science

In this series of experiments it has been attempted to simplify the gravimetric determination of calcium, to make it a more satisfactory and convenient laboratory method.

Maxwell Coulee And The Diversion Of The Rio Mora, Charles R. Keyes

Proceedings of the Iowa Academy of Science

Maxwell Cone or Bald Mountain is a low eminence rising out of the plain at the south foot of the Turkey Mountains, in northeastern New Mexico. The last mentioned mountains form a rather conspicuous circular ridge of high hills having an even crest. These mountains are situated about 30 miles northeast of Las Vegas and about 20 miles east of the Rocky Mountain front. The vast even plains stretching out to the eastward of the Rockies in this region is a part of the Las Vegas plateau.

Concerning A Study Of Kerosene Oils By Physical Methods, G. W. Stewart

Proceedings of the Iowa Academy of Science

Kerosene oil has been the subject of investigation for a number of years, and with the result of improved processes in refining and an illuminant which fulfills a definite need quite satisfactorily. But these investigations have been conducted almost wholly from the point of view of the chemist. This is really not surprising when the complex character of the oils and the necessarily very complex character of the chemical changes in the burning flame are considered. To secure any practical results by physical methods seems at first sight to be hopeless, for does not the illuminating power of the oils …
