Aluminum In Iowa, Charles R. Keyes Jan 1890

Aluminum In Iowa, Charles R. Keyes

Proceedings of the Iowa Academy of Science

Attention is called to the birth of an industry in Iowa that promises to be one of the greatest industries of the State in the near future. It is the establishment of a plant for the production of aluminum. As is well known, this metal is soon to be the metal of the world-replacing largely iron, steel and other metallic substances used in the arts. The properties of aluminum need not be dwelt upon here. The cost of producing the metal has hitherto been the great drawback to its general usage. A few years ago the price was $15.00 or …

Phaenological Notes, L. H. Pammel Jan 1890

Phaenological Notes, L. H. Pammel

Proceedings of the Iowa Academy of Science

Among the many interesting observations in connection with our flora is the relation that plants have to climatology. It is true the question is an agricultural and horticultural one only so far as it bears on questions of our cultivated plants. But with the addition of new plants every year to our list of those cultivated for utilitarian or ornamental purposes, it is important to record exact data in regard to their behavior under cultivation. But in plant climatology all plants should be studied with reference to various climatic conditions.

Artesian Wells In Iowa, R. Ellsworth Call Jan 1890

Artesian Wells In Iowa, R. Ellsworth Call

Proceedings of the Iowa Academy of Science

The demand for artesian waters in the State of Iowa is not to be connected with unfavorable climatal conditions. The State is well watered; a considerable number of rather large streams and numerable smaller ones combine to make it, from a hydrographic standpoint, unique among prairie states. The annual rainfall is a little more than thirty-five inches and chiefly comes at a time of year when every crop necessity is fully supplied. The main grounds upon which artesian waters are sought, therefore, are first, the convenience of such flows for farm and urban use, and second, the supposed purity of …

Geological Structure And Relations Of The Coal-Bearing Strata Of Central Iowa, Charles R. Keyes Jan 1890

Geological Structure And Relations Of The Coal-Bearing Strata Of Central Iowa, Charles R. Keyes

Proceedings of the Iowa Academy of Science

The exposed stratified rocks of central Iowa are made up chiefly of Lower Coal Measure clays, shales and sandstone. In the southeastern portion of the area the upper member (for Iowa) of the Sub-Carboniferous – The St. Louis limestone – is exposed along the Des Moines River. To the westward the socalled Middle Coal Measures and the Upper Coal Measures are represented. Hitherto it has been supposed that the three recognized divisions of the upper Carboniferous rocks in the State have each a maximum thickness of about two hundred feet. Lately, however, the Upper Coal Measures alone have been discovered …

On The Orthopterous Fauna Of Iowa, Herbert Osborn Jan 1890

On The Orthopterous Fauna Of Iowa, Herbert Osborn

Proceedings of the Iowa Academy of Science

The orthoptera are among the most important of the injurious insects of this State, almost all of the species being destructive, and scarcely one that can be considered as of any benefit. A list of the species occurring in the State is therefore of more than scientific interest and becomes important while considering the distribution of the destructive species. The present notes refer almost entirely to the central part of the State, principally in the vicinity of Ames, and there are, doubtless, many other species to be secured by careful collection with special reference to this group in this locality, …

The Gall-Producing Cynipidae Of Iowa, C. P. Gillette Jan 1890

The Gall-Producing Cynipidae Of Iowa, C. P. Gillette

Proceedings of the Iowa Academy of Science

The Cynipidae form one of the most interesting, but one of the least studied families of the Hymenoptera. It is the object of this paper to encourage the collection and study of the gall-producing Cynipidae of the State. The species here mentioned have, with one exception (Rhoditcs multispinosa), been taken by the writer in the past two years in the vicinity of Ames, Iowa. There can be no doubt but what two or three times as many species occur in the State.

Abnormal Pelage In Lepus Sylvaticus, Herbert Osborn Jan 1890

Abnormal Pelage In Lepus Sylvaticus, Herbert Osborn

Proceedings of the Iowa Academy of Science

The specimen of rabbit exhibited was killed a few miles south of Ames, in the early part of the past winter (1889-1890), and sent to me through Mr. H. P. McLain, of Ames. It is remarkable in having two extensive patches of very long hair, one running along each side of the back from the ears to the hips, so long as to droop down the sides to the lower line of the body, and also similar long hairs, in tufts, in front of the ears and on the upper part of each leg, The color is about like that …

On Some Carboniferous Fossils From Jackson County, Iowa, Herbert Osborn Jan 1890

On Some Carboniferous Fossils From Jackson County, Iowa, Herbert Osborn

Proceedings of the Iowa Academy of Science

While on a hasty visit to Jackson county, Iowa, this summer, I was taken, by the kindness of Hon. C. M. Dunbar, to a lime quarry near Monmouth, in the western part of that county, about sixteen miles from Maquoketa. I found there in the possession of Mr. Stewart, the owner of the quarry and kiln, some fine specimens of Lepidodron and Calamites, which naturally excited my curiosity (especially as they were so large as to preclude the idea of their having been brought from a distance as specimens), and led me to make special inquiry as to their occurrence.

Notes On The Geology Of Northwestern Iowa, J. E. Todd Jan 1890

Notes On The Geology Of Northwestern Iowa, J. E. Todd

Proceedings of the Iowa Academy of Science

I handed in the subject of this paper, intending to throw together various notes which have been accumulating for several years. I recently took a trip to the region under consideration intending to visit several localities and examine the borings of several wells, which, however, I was prevented from doing for lack of time. Had I been able to procure careful notes from all the wells I should be more decided on several points stated below.

The Shore-Lines Of Ancient Glacial Lakes, J. E. Todd Jan 1890

The Shore-Lines Of Ancient Glacial Lakes, J. E. Todd

Proceedings of the Iowa Academy of Science

As most are aware, there are areas of drift external to any terminal moraines, the origin of which is still in dispute. On general principles, it would be expected that numerous lakes would have frequently occurred during the Ice Age. As the ice advanced, streams would frequently be dammed, and their channels more or less changed, and the might of the ice, with its chilling effect, in level areas would not infrequently produce a subsidence toward the ice, which would often become filled with the floods escaping from the ice.

Eastern Extension Of The Cretaceous In Iowa, Charles R. Keyes Jan 1890

Eastern Extension Of The Cretaceous In Iowa, Charles R. Keyes

Proceedings of the Iowa Academy of Science

In connection with a casual reference to the cenological features of Central Iowa mention may be made to the recent discovery in the drift at Des Moines of a mass of rather soft ferruginous sandstone charged with fossils of unmistakable cretaceous type, the greater part being in a good state of preservation. When first discovered the mass was perhaps two feet in diameter and contained upwards of a dozen species of fossils. A few of the best preserved specimens were taken at the time; and the place revisited a few days later for the purpose of securing the entire piece, …

Evolution Of Strophostylus, Charles R. Keyes Jan 1890

Evolution Of Strophostylus, Charles R. Keyes

Proceedings of the Iowa Academy of Science

Recently a large series of the most important species of Platystoma and Strophostylus was examined and the matrix carefully removed from the apertural portions of many of the shells. The structural features disclosed in the various forms show a relationship between the two established genera that was long suspected. The two types are now regarded as identical.

Age Of Certain Sandstones Near Iowa City, Charles R. Keyes Jan 1890

Age Of Certain Sandstones Near Iowa City, Charles R. Keyes

Proceedings of the Iowa Academy of Science

The sandstones under consideration lie in old gorges in Devonian limestone a short distance north of Iowa City. On account of the presence of plant remains, which, however, were too fragmentary for identification, Hall regarded the arenaceous deposits as belonging to the upper coal measures. Others visiting the places, since the announcement of the discovery in 1858, have adopted the same view as to the age of the rock without attempting to question the correctness of the assumption, or to obtain further evidence.

On A Quaternary Section Eight Miles South-East Of Des Moines, Iowa, Charles R. Keyes, R. Ellsworth Call Jan 1890

On A Quaternary Section Eight Miles South-East Of Des Moines, Iowa, Charles R. Keyes, R. Ellsworth Call

Proceedings of the Iowa Academy of Science

The section is located on the line of the Wabash railway about two miles below the little station of Hastie. It forms a continuous exposure of nearly three-fourths of a mile in length; and in some places has almost a vertical face of from 125 to 150 feet. It is capped by twenty feet of loess, carrying characteristic fossils such as Succinea arara Say; Succinea obliqua Say; Helicina occulta Say; Pupa muscorum Linne; Vallonia pulchella Muller; Zonites arboreus, Say; Patula strigosa, Gould; and a large Helix, probably Mesodon thyroides, Say. Below the loess to the track level the section is …

Note On The Differences Between Acervularia Profunda Hall, And Acervularia Davidsoni Edwards And Haine, S. Calvin Jan 1890

Note On The Differences Between Acervularia Profunda Hall, And Acervularia Davidsoni Edwards And Haine, S. Calvin

Proceedings of the Iowa Academy of Science

The original description of Acercularia profunda Hall, is found in Hall's Report on the Geological Survey of Iowa, published in l858. The specimens on which the species was founded came from near Independence, in Buchanan County, Iowa. In the same report Professor Hall, not without some hesitation identifies another form found abundantly throughout the Devonian area in Iowa, with Acercularia davidsoni Edwards and Haine. This so far as I have been able to ascertain, was the first time the name had been employed in a work published in America; for although Edwards and Haine's specimens came from near Jeffersonville, Indiana, …

Prismatic Sandstone From Missouri, Erasmus Haworth Jan 1890

Prismatic Sandstone From Missouri, Erasmus Haworth

Proceedings of the Iowa Academy of Science

On the right bank of the St. Francois River, in S.31; T.33, N.; R. 6. E., about 200 yards southwest of the St. Louis Granite Company's quarry, near Knob Lick, Madison County, Mo., is a little sandstone ridge, trending northwest and southeast, nearly 200 yards long, 10 yards wide, and not more than 8 to 10 feet high above the nearly level ground on either side. The country rock here is the Cambrian sandstone, which overlies the granite, as is beautifully illustrated at the quarry nearby. This little ridge is interesting on account of the peculiar form of the sandstone …

On An Abnormal Hyoid Bone In The Human Subject, R. Ellsworth Call Jan 1890

On An Abnormal Hyoid Bone In The Human Subject, R. Ellsworth Call

Proceedings of the Iowa Academy of Science

The hyoid bone lies at the base of the tongue just above the upper border of the thyroid cartilage. It is not articulated with any other bone in the body. It is usually studied as consisting of five parts, all of which may readily be distinguished in the normal specimen, especially in the young subject. There is the body of the bone, or the basi-hyal; there are also two cerato-hyals, or lesser cornua, aud two thyro-hyals, or greater cornua. The whole forms a horse-shoe shaped bone to which the name hyoid has been given in allusion to the shape of …

Some Experiments For The Purpose Of Determining The Active Principles Of Bread Making, Minnie Howe Jan 1890

Some Experiments For The Purpose Of Determining The Active Principles Of Bread Making, Minnie Howe

Proceedings of the Iowa Academy of Science

This paper described a series of experiments made by the author at the Iowa State University during the winter and spring of 1891, together with their results. The problem was to separate the bacterium, Bacillus subtilis, and the yeast plant, Saccharomyces cerevisae, found together in ordinary soft yeast, to obtain pure cultures of each, and to determine the part each played in bread making,

Notice Of Arrow Points From The Loess In The City Of Muscatine, F. M. Witter Jan 1890

Notice Of Arrow Points From The Loess In The City Of Muscatine, F. M. Witter

Proceedings of the Iowa Academy of Science

No other question has ever engaged the attention of man more than that which relates to the origin and destiny of his race. Many theories have been advanced to account for man's origin and there is likewise great diversity of opinion as to his destiny. Evolution, it seems to one, is competent to explain the natural order of things from the crystal to man. Except we build on the sure foundation of the past and present all speculation concerning man's destiny must be conjecture.

The Gas Wells Near Letts, Iowa, F. M. Witter Jan 1890

The Gas Wells Near Letts, Iowa, F. M. Witter

Proceedings of the Iowa Academy of Science

In the early part of December, 1890, Mr. T. L. Estle, living in section 3, township 75, north, range 4, west 5th p. m., sunk a well on his farm for water. In drift at a depth of about one hundred feet he struck gas, which burned readily but in two or three days the gas ceased to flow. Between forty and eighty rods west of this place, about the same time Mr. R. M. Lee bored for water. At about one hundred feet he failed to get water and stopped boring. In the evening he commenced to pull out …

Composite Milk-Samples In The Laboratory, G. E. Partick Jan 1890

Composite Milk-Samples In The Laboratory, G. E. Partick

Proceedings of the Iowa Academy of Science

Composite milk-samples for use at creameries, as a means of saving labor in the valuing of milk by any of the "oil tests,'' I first proposed (in detail) in Bulletin No. 9, of the Iowa Experiment Station, May 1890. The preserving agent there recommended for preserving the samples was corrosive sublimate, HgCl2, numerous experiments having shown that it preserves the mechanical, as well as the chemical, condition of milk better than any other common antiseptic. For use in creameries I insisted that the sublimate have mixed with it some suitable aniline color, as a guard against accidental poisoning; and …

On A New Astatic Galvanometer With A Single Spiral Needle, Launcelot W. Andrews Jan 1890

On A New Astatic Galvanometer With A Single Spiral Needle, Launcelot W. Andrews

Proceedings of the Iowa Academy of Science

Two types of astatic galvanometer are in common use. In one, two needles with poles reversed are united to form a rigid system, in the other, a single suspended needle is employed, the directive force of the earth's magnetism being compensated by an immovable magnet suitably placed north or south of the needle. (Hauy's method.)
