The Inheritance Of Syndactylism, Henry Albert

Proceedings of the Iowa Academy of Science

An instance of thirteen cases of syndactylism (or fused or webbed fingers or toes), traced through four generations was reported. The element of heredity is obviously apparent. In view of the recent report of a family with cases of syndactylism in which the inheritance of the abnormal union of the digits apparently conformed to Mendel's law, as a dominant character, an effort was made to determine if the Mendelian law also applied to the cases in question. It was determined that although the disease was due to a factor which was apparently dominant rather than recessive it did not conform …

The Theory Of Binaural Beats - An Experimental Contribution, G. W. Stewart, Harold Stiles

Proceedings of the Iowa Academy of Science

The experiments here reported were performed in order to secure evidence concerning the cause of the additional maxima which occur in binaural heats. (See G. W. Stewart, Physical Review, Series 2, 3, p. 146, 1914, for a description of the phenomena.) These additional maxima occur at certain phase differences, and the change in these phase differences should depend upon the frequency of the tones, but not upon the frequency of the beats. If the additional maxima are caused by interaural conduction then, as it can be shown, the phase differences should vary as the frequencies. In the accompanying curve the …

The Flora Of The Rainy River Region, Harriette S. Kellogg

Proceedings of the Iowa Academy of Science

There is no evidence accessible to the writer that a critical study of the flora of this region has ever been made, although several of the early explorers must have passed over this part of Minnesota.

The Ecological Histology Of Prairie Plants, Ella Shimek

Proceedings of the Iowa Academy of Science

The investigation, the result of a part of which is here presented, was made for the purpose of ascertaining the character of the various structural adaptations to environment which appear in the ordinary plants of our Iowa prairies. Of the 271 characteristic species of our prairies 65, representing a wide range of families and genera, were selected for these studies. The material for this purpose was collected on the dry prairie ridges or bluffs in Harrison county, and on the less rugged prairie in the vicinity of the Okoboji lakes, and at Iowa City.

The Flora Of The Ledges Region Of Boone County, Iowa, William W. Diehl

Proceedings of the Iowa Academy of Science

In the south-central part of Boone County is an area that possesses characteristic plants as well as peculiar geological and topographic features. This is located four miles directly south of Boone and extends for about two miles south toward and along the Des Moines River. Its name "The Ledges" is appropriate because of striking sandstone cliffs from ten to over forty feet in height, extending beyond the perpendicular in some cases as much as twelve feet. This ledge rock here comprises an island of younger massive sandstone surrounded unconformably by somewhat older Carboniferous layers, which are of different structure. The …

The Native And Cultivated Forest Trees And Shrubs Of The Missouri River Basin, L. H. Pammel, G. B. Macdonald, H. B. Clark

Proceedings of the Iowa Academy of Science

At the twentieth annual session of the Iowa Academy of Science held in Ames on April 20 and 21, 1905, Dr. C. E. Bessey of the University of Nebraska in his address on the Forest trees of Eastern Nebraska, expressed the wish that the Iowa botanists would join with those of Nebraska in making a tree survey of the two sides of the river. During the season of 1914 one of us received a letter from Prof. Sargent asking us to furnish him data on the distribution of Iowa trees. We found, however, that our knowledge of some species was …

An Anomalous Hickory-Nut, Guy West Wilson

Proceedings of the Iowa Academy of Science

During the fall of 1914 the writer observed in the vicinity of Iowa City a tree of the common shag-bark hickory (Carya ovata (Mill.) K. Koch.) which produced a number of abnormal nuts.. As none of these were found with the husk intact no data can be given except for the nuts themselves. Bicarpillary fruits were not uncommon on this tree as at least a dozen examples were found without making a careful search. In most instances the paired nuts separated readily and showed no tendency toward adhesion. They were, however, very much flattened on the appressed surfaces. A …

An Exobasidium On Armillaria, Guy West Wilson

Proceedings of the Iowa Academy of Science

In one locality near Iowa City Armillaria mellia was attacked by a parasitic fungus which caused extensive hypertrophy of the upper region of the pileus of its host without rendering the gills sterile. The parasite developed a hymenium which spread over a series of thin, sharp-edged and highly convoluted ridges or gills. The microscopic characters show the fungus to be closely related to that which has been designated Exobasidium mycetophilum (Peck) Burt.

Pioneer Plants On A New Levee, Frank E. A. Thone

Proceedings of the Iowa Academy of Science

A year ago this spring the city of Des Moines cut a new channel and mouth for the Raccoon River, causing it to change its course for a distance of about half a mile and to empty into the Des Moines River a little more than half that distance below its old mouth. The bulk of the excavated material was piled upon the south bank of the new channel to form a levee about fifteen feet high, sixty feet wide at the base, and twelve feet wide at the top, with a space of twelve feet intervening between the foot …

A Convenient Standard Cell, Dieu Ung Huong, J. N. Pearce

Proceedings of the Iowa Academy of Science

Until recently both the Clark and the Weston cells have served as standard sources of electromotive force. Both of these consist of an amalgam of a metal as the anode covered by a saturated solution of the sulphate of the metal and this in conjunction with mercury and mercurous sulphate which serves as the cathode.

An Improved Heating Apparatus For Maintaining Constant Temperatures In Work With Polarimeters And Refactometers, J. N. Pearce

Proceedings of the Iowa Academy of Science

In the course of some work upon the effect of temperature upon the specific rotation of optically active substances in solution, it was found necessary to maintain constant temperatures over long periods of time. The conditions demanded that the heating apparatus be one which is simple and convenient and at the same time one which permits the easy reproduction of any given temperature.

The Extension Of The Wisconsin Drift Southwest From Des Moines, John L. Tilton

Proceedings of the Iowa Academy of Science

At the last meeting of the Academy I called attention to an extension of the Wisconsin drift south, past Valley Junction into the region which was generally understood to be within the area of Kansan drift. It was with a view to extending observations further south in that direction than was possible in the time previously at my disposal that trips were made in 1914 extending the area examined east to the Army Post, west to the ravines in the southwest portion of Polk county, and, as far south as Norwalk, Cummings and Orillia in Warren county and west to …

The Occurrence Of Barite In The Lead And Zinc District Of Iowa, Illinios And Wisconsin, W. D. Shipton

Proceedings of the Iowa Academy of Science

According to the reports of the Iowa, Illinois, and Wisconsin Geological Surveys natural crystals of barite are found rarely in the Lead and Zinc District of Iowa, Illinois, and Wisconsin. On account of the rarity of distinct crystals, considerable interest attaches to the finding of these crystals in this region at Hanover, Illinois. In the possession of Mr. T. D. Shipton of Hanover, are sixty or more well defined crystals of barite; it is to him that the writer is indebted for the material from which this paper was prepared.

The 4-Nitro-5-Methyl-2-Sulphobenzoic Acid And Some Of Its Derivatives, William J. Karslake, Perry A. Bond

Proceedings of the Iowa Academy of Science

The 4-nitro-5-methyl-2-sulphobenzoic acid has been investigated to a limited extent as one of the products formed when the 6-nitro-1, 3-dimethyl-4-sulphonic acid is oxidized by potassium permanganate in dilute alkaline solution. Previous to this research, the only record of its preparation was by Limpricht, in which case only a small amount of the neutral potassium salt was isolated. He gives this as occurring with one-half a molecule of water of crystallization, but does not state which of the two methyl groups of the original acid had been oxidized. The neutral potassium salt does not seem to contain any water of crystallization, …
