A Study Of The Physical Properties Of Solutions Of Lithium Chloride In Amyl Alcohol, Launcelot W. Andrews, Carl Ende

Proceedings of the Iowa Academy of Science

There can be no doubt that much light can be thrown upon the nature of electrolytic processes by a systematic examination of electrolytes containing no water; for the principles of the Electrolytic Dissociation Theory, if general, must be valid, not only for solutions in water, but also for all others, and conclusions derived from the study of the former can best receive independent confirmation or rebuttal by a careful investigation of the latter. The questions upon which such an investigation should bear are chiefly these: 1. Does Ostwald's Law of Dilution hold good for non-aqueous solutions? 2. In what way …

Upper Carboniferous Of Southwestern Iowa, E. H. Lonsdale

Proceedings of the Iowa Academy of Science

The district at hand is one somewhat remote from any known field of productive Coal Measures, but being Upper Carboniferous in age is a region to which considerable geological and economical interest has been attached. There has always been an anticipation of finding heavy fuel veins, but as yet these looked-for strata have not been positively located. Reports, often manufactured, and the meeting of thinner veins of coal, have led to the increased expectations now prevalent in the district.

Volatility Of Mercuric Chloride, Abbott C. Page

Proceedings of the Iowa Academy of Science

Solutions of mercuric chloride were evaporated on a water bath with the following results.

Report Of The Committee On State Fauna, C. C. Nutting

Proceedings of the Iowa Academy of Science

In November last the chairman of this committee sent out a number of postal cards to the zoologists of the Academy, requesting them to forward their notes regarding the appearance of animals new to the state or to certain localities, and any items of interest concerning the geographical distribution of the animals of Iowa. The response was anything but encouraging, as only three members made any answer whatever, and none of these had more than a single note to offer. This will account, in part at least, for the meagerness of this report.

Topaz Crystals Of Thomas Mountain, Utah, Arthur J. Jones

Proceedings of the Iowa Academy of Science

In the summer of 1891 it was the privilege of the writer to visit what is known as Topaz Mountain in southern Utah. It is about thirty-five miles south of the northern end of the Dugway Mountains, called by Simpson the Thomas Range, twenty-five miles northwest of Deseret, forty miles north of Sevier Lake, and about the same distance west of Eureka, Utah.

The mine herein described is located in Allamakee County, about five miles northwest of Lansing (Tp. 99 N., R. IV. W., Sec. 10, Nw. qr.). It is owned and operated by the Lansing Mining and Smelting Company, of which Hon. J. H. Trewin is president.

Structure Of The Seed Coats Of Polygonaceae, Emma Sirrine

Proceedings of the Iowa Academy of Science

Much work has been done on the structure of the seed coats of different orders of plants. The objects of studying the seed coats of plants microscopically are two-fold. First to help detect adulterated foods, etc., and in this respect the study has been of very great value. Second, to aid in the distinction and separation of species.

Glacial Markings In Southeastern Iowa, Francis M. Fultz

Proceedings of the Iowa Academy of Science

In the third annual report of the Iowa Geological Survey Dr. C. R. Keyes has treated, at considerable length, of the glacial scorings in Iowa. Among others, several localities were given from Des Moines County, of which two were described somewhat in detail by the present writer. Since the above mentioned article was prepared a somewhat more extended and minute search has been made, with the result that several other localities showing glacial scratches have been discovered. Also, some attention has been given to a study of the phenomena accompanying these markings, with a view of determining the general direction …

Address Of The Retiring President - Recent Advances In The Theory Of Solutions, Launcelot W. Andrews

Proceedings of the Iowa Academy of Science

Ten years ago nothing was known of the molecular magnitudes of substances which could not be converted into the gaseous condition. Concerning the constitution of the much greater number of compounds that exist only as solids or liquids, our ignorance was complete.

Interloessial Till Near Sioux City, Iowa, J. E. Todd, H. Foster Bain

Proceedings of the Iowa Academy of Science

Till and loess are well known deposits and need not be defined. It is a peculiar and anomalous relation between the two which it is proposed to describe in this paper. It is well known that the till almost universally occupies a position below the loess wherever the two are found in the same section. A few cases only have been noted where the reverse is true. Such an instance was described by McGee and Call in an account of the loess near Des Moines. Similar occurrences have been reported by other observers from central and eastern Iowa. These may …

Record Of The Grinnell Deep Boring, Arthur J. Jones

Proceedings of the Iowa Academy of Science

Work was begun on the deep well in October, 1892, but it was not completed until the following year. The ordinary churn drill was used and the hole was first drilled eight inches in diameter, but later the upper portion was enlarged to ten inches. The record has been more carefully kept than is usual in drilling such wells, but cannot be relied upon as absolutely exact. In many cases the fragments of the overlying stratum are mixed with that underneath, and the thickness of each formation cannot be exactly determined. This renders the results only approximately correct, but it …

Maquoketa Shales In Delaware County, Samuel Calvin

Proceedings of the Iowa Academy of Science

From the relation of Delaware County to the great Niagara escarpment it would scarcely be expected that rocks older than the Upper Silurian would be found within its limits. Upper Silurian sediments indeed constitute the rocks that may be said to be normal to the entire county. They cover probably ninety-nine per cent of its area. Without exception all the higher lands are occupied by them, and most of the valleys have a floor of Niagara dolomite. Still some of the valleys have cut through the Niagara limestone down into the underlying shales of the Maquoketa age, and very many …

A Kymograph And Its Use, W. S. Windle

Proceedings of the Iowa Academy of Science

The science of physiology in its present condition owes much of its advancement to the skillful manipulation of cunningly devised apparatus. Without the successful invention of delicate mechanical appliances many of the profound researches of Foster, Du Bois, Raymond, McKendrick, Martin and others would never have been possible. It must be granted, however, that invention and skill in manipulation have been supplemented by clear and comprehensive interpretation of results obtained, and it is to the latter that most credit is due. In emphasizing the value of scientific apparatus and its use, we recognize the imperative need of a fundamental knowledge …

Changes That Occur In Ripening Corn, C. F. Curtiss

Proceedings of the Iowa Academy of Science

The great importance of corn as a forage and grain crop has induced the writer to record some observations in noting the successive changes that occur in the ripening process of this plant. These observations have been confirmed and emphasized by the generally unsatisfactory experience of the present season in the use of forage made from the immature corn plant.

A Chemical Study Of Honey, W. H. Heileman

Proceedings of the Iowa Academy of Science

It has long been known that honey is composed chiefly of dextrose and levulose (reducing sugars), with a small per cent of sucrose. These, with water and ash, are generally all that is given in an analysis, and their sum invariably falls from three to ten per cent below one hundred. The results of analyses vary with different examples, as shown by the following summary of results, obtained by different observers.

Plant Lice Infesting Grass Roots, Herbert Osborn, F. A. Sirrine

Proceedings of the Iowa Academy of Science

During the fall of 1889 the senior author of this paper determined that a species of plant louse, infesting roots of annual grasses was identical with the "Dogwood plant louse" (Schizoneura corni Fabr.), carrying the work far enough to prove that the winged forms could be transferred from grass roots to dogwood, on which they colonized. As he found the root forms principally on annual grasses which were of no economic value, it was naturally a question of interest to determine whether they might affect forage plants. Furthermore, the occurrence of non-migratory forms on certain of the grasses examined, left …

Some Bred Parasitic Hymenoptera In The Iowa Agricultural College Collection, Alice M. Beach

Proceedings of the Iowa Academy of Science

This list is prepared from the material in the collections of the Iowa Agricultural College and the Iowa Experiment Station, and may be considered a preliminary record of the parasitic Hymenoptera of the state. In its preparation the notes and records made by Prof. C. P. Gillette, while entomologist of the Experiment Station, have been freely consulted and largely drawn upon. The list is still incomplete for much material yet remains to be classified and records to be filled out.

Distribution Of Some Weeds In The United States, Especially Iva Xanthifolia, Lactuca Scariola, Solanum Corolineum And Solanum Rostratum, L. H. Pammel

Proceedings of the Iowa Academy of Science

One of the interesting parts dealing with geographical botany is the question of the distribution of plants over the earth's surface, where man has played an important part. Many changes have occurred in the character of our North American flora since it has been occupied by man. In many cases it has become quite impossible to tell when and where plants were first introduced. We have, it is true, in some cases records when plants were introduced, but in the vast majority of cases there were no records at hand. Early collectors in many cases simply mentioned vague localities with …

Lichens Collected By Dr. C. C. Parry In Wisconsin And Minnesota In 1848, Bruce Fink

Proceedings of the Iowa Academy of Science

The lichens of this collection are all conspicuous foliaceous or fruticulose forms. One striking feature is the evident care of the collector to preserve excellent specimens. There are no notes accompanying each packet. However, if all were collected in one of the above named states as is stated on the card accompanying the package sent me, the collection is a very good one, as Cetraria Islandica, Evernia vulpina, and Stereocaulon puschale, are probably new or very rare in either state. The same may probably be said of the two Umbilicarias listed.

Study Of Glands In The Hop-Tree, Cassie M. Bigelow

Proceedings of the Iowa Academy of Science

In studying this plant, the main object has been to bring out the characteristics of the glandular structures in Ptelea trifoliata and the differences between the glandular structure of this plant and other used in a like way as the hop.

Graphic Representation Of The Properties Of The Elements, T. Proctor Hall

Proceedings of the Iowa Academy of Science

In Mendeleeff's classification the elements are arranged in order on a plane surface, so as to increase along one axis in atomic weight, and along the other axis in valence. The properties of an element can then, to some extent, be inferred from its relation to the others on the diagram. Some of the relations are found to be better expressed when the surface is made cylindrical.

Pollination Of Cucurbits, L. H. Pammel, Alice M. Beach

Proceedings of the Iowa Academy of Science

During the season of 1892 one of us was engaged in crossing some of the cultivated cucurbits. Incidentally some attention was given to their pollination. As comparatively little has been published concerning the pollination of these plants, these notes may be of interest.
