Notes On Iowa Saprophytes, Thomas H. Macbride

Proceedings of the Iowa Academy of Science

The saprophytic fungi of Iowa have been very slightly studied. Owing to their high economic importance parasitic forms have claimed almost exclusively the attention of mycologists. Pure science, however, must not be neglected. Without it applied science is impossible and no study of natural objects is more praiseworthy than that which seeks to know these for themselves alone.

Notes On Some Iowa Reptiles, M. P. Somes

Proceedings of the Iowa Academy of Science

The reptiles, while scarce in number of individuals and relatively scarce in number of species in the Iowa fauna, still constitute a group of considerable importance from an economic standpoint as well as zoologically. The group is very generally neglected, this possibly in part because of the almost universal prejudice and in part because of the somewhat scattered and technical nature of the literature. But little has appeared concerning the Reptilia of Iowa since the Osborn Catalogue of the Animals of Iowa and since, from a study of the material in the museum of Iowa University and from notes and …

Studies In Variation Of Red Clover, Edna C. Pammel, Clarissa Clark

Proceedings of the Iowa Academy of Science

Variation in Trifolium pratense presents many interesting problems, some of which have been under consideration during the past two seasons by the contributors to this paper. General relationships between number of flowers in the head, and number of seeds produced, the influence of soils, and seasons, comparative dimensions of the flowers, and of pollen grains, were the particular features studied.

Vaccination Against Typhoid Fever, Henry Albert

Proceedings of the Iowa Academy of Science

The term vaccination was originally used to designate the introduction of material from pustules of cows affected with cowpox into the human being to protect against smallpox. Such produced a mild form of the disease and conferred immunity to the more severe type as represented by smallpox proper. The vaccine represents, then, a weakened or attenuated form of the virus. The term, as now used, applies to the virus of any infectious disease, —the virulence of which virus has been diminished.

Volcanic Phenomena Of Coon Butte Region, Arizona, Charles R. Keyes

Proceedings of the Iowa Academy of Science

It will be recalled that Coon Butte is a low eminence, with a shallow depression in the summit about half a mile across that has become widely known on account of the supposition that this crater-like basin was formed by a huge meteor striking the earth at this point and throwing up the low wall all around. Contrary to the recently expressed views regarding the origin of this remarkable crater the most critical evidences seem to indicate that this feature of the local landscape is only one of the many manifestations of the explosive type of vulcanism so prevalent throughout …

The Development Of Lymph Channels In Turtles By The Fusion Of Mesenchymal Spaces, Frank A. Stromsten

Proceedings of the Iowa Academy of Science

The theory that the lymphatic system is budded off from the venous system is a direct product of a special method of investigation, i.e., the injection method.

Illuminating Engineering - A New Profession, Arthur H. Ford

Proceedings of the Iowa Academy of Science

Since the time of the cave dwellers men have found artificial illumination a convenience if not a necessity; but only within the present century has the design of illumination system been considered for such importance as to become a special branch of engineering. In fact the first American college course bearing the name illumination was planned and taught by the writer in 1901. This was given at the University of Colorado and occupied two periods a week for a semester. The profession is so new that it is not mentioned in even the most recent dictionaries; so it is thought …

Glaciated Rock Surfaces Near Linn And Near Quarry, Iowa, With A Table Of The Bearings Of Glacial Striae In Iowa, W. H. Norton

Proceedings of the Iowa Academy of Science

Linn is a junction of the Chicago, Rock Island and Pacific Railway, situated four miles northwest of Cedar Rapids. About one mile west of this station a rock cut, formerly used by the Chicago, Milwaukee and St. Paul Railway, scarps the bluffs bordering the Cedar River. At the extreme north end of the cut, 14 feet above the trackway, and about 75 feet above the level of the river, there is exposed by the retreat of a cover of yellow till and loess a surface of less than two feet square, developed on glaciated limestone belonging to the Acervularia davidsoni …

Some Fungus Diseases Of Trees, L. H. Pammel

Proceedings of the Iowa Academy of Science

The researches of Hartig, Tubeuf, Metcalf, Von Schrenk, and others have shown that quite a large number of wood destroying fungi belong to the Agaricaceac, Hypochnaceae, Polyporaceae, Hydnanceae, and Thelephoraceae.

Some Features Of The Bering River Coal Field, Alaska, G. F. Kay

Proceedings of the Iowa Academy of Science

The Bering River coal field lies a few miles inland from the north shore of Controller Bay, an indentation of the Pacific coast about 1,200 miles from Seattle. In this field are the Cunningham claims which were given much publicity in connection with the Pinchot-Ballinger controversy. Much of the coal area is within the drainage basin of the Bering River. To the north of the field is the Martin River glacier, with the lofty, snowcapped Chugach range of mountains beyond; to the east of the field, and extending for many miles, is the Bering Pielmont glacier.

Graphics Of Ore-Origin, Charles R. Keyes

Proceedings of the Iowa Academy of Science

In the main ore deposits are precipitated in aqueous solutions. Solution, transportation and deposition of ore-materials are distinctly processes operating through the medium of subterranean waters. The sources of the ore-minerals, the courses they follow through the geologic formations, and the immediate causes of their localization, are factors of prime importance in the consideration of ore-genesis. Obscure as is the migration and changes of ore-materials it is possible, as will be seen presently, to represent graphically the general courses.

Notes In Regard To Efficiencies Of Luminous Flames, G. W. Stewart

Proceedings of the Iowa Academy of Science

An investigation of the efficiency of luminous flames would be of interest. Results obtained incidentally were studied, showing that a cylindrical acetylene flame is not so efficient as a flat acetylene flame when judged by the proportion of its radiant energy that is visible. The amount of visible radiant energy that a given quantity is able to furnish should also be considered. Experiments with a flat kerosene flame show a height of flame at which the candle-power-hours-per-gram is a maximum. The problem of obtaining the most efficient flame, in the broadest sense, is complex. It is advisable to get the …

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.
