The President's Address, Thomas H. Macbride

Proceedings of the Iowa Academy of Science

When, a short time ago, I was advised by our indefatigable secretary that by virtue of having been chosen vice-president of this body, the duty of making the presidential address fell to my share, I was somewhat disconcerted. I was at first inclined to push my honors from me and to say that inasmuch as no time remained for the preparation of a suitable discourse, the presiding officer would simply waive his prerogative in that particular and pass to the next order of business.

Additions To The List Of Hemiptera Of Iowa, With Descriptions Of New Species, Herbert Osborn

Proceedings of the Iowa Academy of Science

A number of additions to the Hemipterous fauna of the state have been made during the last year, either by collection or by the determination or description of specimens previously in hand, and although there are certainly many others to add it seems desirable to record such as have come to notice. In many cases the record greatly extends the range of the species as heretofore known.

Is The Loess Of Aqueous Origin?, B. Shimek

Proceedings of the Iowa Academy of Science

Organic remains furnish the best criterion for the measure of conditions which prevailed during any given age of the earth's geological history, provided, of course, that their relation to the deposit can be clearly shown.

Do The Lower Animals Reason?, C. O. Nutting

Proceedings of the Iowa Academy of Science

For the average layman to enter into a discussion involving psychological matters is surely a rather hazardous proceeding and indicates a temerity that needs some apology. Your speaker, although not a psychologist, has become greatly interested in the evidences of mind that have impressed themselves upon him in his study of animals, and has had his interest greatly stimulated by the perusal of the works of two writers, one of whom discusses animal psychology from the side of the naturalist, and the other from the side of the psychologist. With the latter writer I have been led into the most …

The Nerve Cells Of The Shark's Brain, Gilbert L. Houser

Proceedings of the Iowa Academy of Science

The sharks are of the greatest interest to the morphologist on account of the many ancestral characters of their organization. The researches of recent years indicate that they represent quite well the primitive stem of the jaw-bearing vertebrates. With this fact in mind, the importance of the study of the shark's brain is at once apparent. For obvious reasons modern neurological investigation has been largely concerned with the mammalian brain in general and the human brain in particular. But the structures here are highly specialized, and their significance cannot always be thoroughly understood. In order to unravel the tangled threads …

The Uses Of Formaldehyde In Animal Morphology, Gilbert L. Houser

Proceedings of the Iowa Academy of Science

By the term formaldehyde, I wish to designate a 40 per cent solution of the gas formaldehyde in water. Several articles answering to this description have been placed on the market under trade names such as the "Formalin" of Schering, the "Formol" of Merck, and the "Formalose" of Richards & Co. So far as I have tested these various preparations, they all agree as to composition, and yield perfectly similar results. My attention was first directed to formaldehyde as a morphological reagent in July, 1894, and I have been using it in my work, and have experimented with it in …

Proceedings Of The Eleventh Annual Session Of The Iowa Academy Of Sciences: Staff & Committee Reports, G. E. Finch, A. A. Veblen, A. G. Leonard

Proceedings of the Iowa Academy of Science

The eleventh annual session of the Iowa Academy of Sciences was held in committee room No. 1 of the capitol building in Des Moines, December 29 and 30, 1896. In business sessions the following matters of general interest were acted upon.

The State Quarry Limestone, Samuel Calvin

Proceedings of the Iowa Academy of Science

At the state quarries, or North Bend quarries, in sections 5 and 8 of Penn township, Johnson County, Iowa, there is a body of limestone of Devonian age, possessing marked characteristics which set it off sharply from the rest of the Devonian in the upper Mississippi Valley. The formation has a thickness of about forty feet. At present there is some uncertainty as to its exact taxonomic relations.

The Illinois Biological Station, L. S. Ross

Proceedings of the Iowa Academy of Science

In Europe there are twenty-seven or more marine biological stations, one in Japan and five in the United States. The attention of biologists has been given mostly to the study of marine life, but some of the inland scientists are taking to the fresh water, leaving the marine life to be salted down by those near at hand. But it is only of late years that a few zoologists have bethought themselves to halt in their rush to the marine stations and cast a microscopic squint at the myriads of forms dashing and crowding through the water of the lakes …

Waverly Phoenix, May 29, 1895

Waverly Phoenix

The Waverly Phoenix was a Democratic weekly German-language newspaper published from 1884 to 1924 in Waverly (Bremer County), Iowa. Articles in the newspaper reflect the experiences and viewpoints of first- and second-generation German immigrants who had settled in Iowa.

Some Facts Brought To Light By Deep Wells In Des Moines County, Iowa, Francis M. Fultz

Proceedings of the Iowa Academy of Science

During the past year a number of deep wells were sunk in Des Moines County. Some of them reached such extraordinary depths before touching rock, or without touching rock at all, as would clearly show the presence of buried river channels. In a paper presented before this society a year ago I stated that the pre-glacial and present drainage systems in this region were practically the same. From facts recently brought to light I must necessarily change that opinion. To what extent remains yet to be seen.

The Nomenclature Question Among The Slime-Moulds, T. H. Macbride

Proceedings of the Iowa Academy of Science

That a man's difficulties are often of his own creating is a fact patent in science as in other fields. The imperfections of our methods form ever increasing nets of complexity about the feet of our progress. No one feels this more keenly than the naturalist, especially he who would attempt to give more exact account of some limited group or series of animals or plants. No matter how carefully he may arrange his materials, no matter how industriously he may have worked out the various problems of structure and morphology, there comes at last to plague him, to hinder …

Annual Address Of The President - Needed Changes In Scientific Methods, H. W. Norris

Proceedings of the Iowa Academy of Science

We live in a period that sees wonderful attainments in science and art, so that in theory and practice many think the summum bonum has been reached. It is pre-eminently the age of science and the application of scientific methods to all phases of human activity. The forces of nature have been made subject to the will of man. The relations of man to his surroundings have been carefully considered. The province of human intellect has been made the ground of scientific investigations. We now see scientific methods foremost and uppermost, and all human thought is more or less permeated …

Origin And Significance Of Sex, C. C. Nutting

Proceedings of the Iowa Academy of Science

This paper is not presented as a contribution to our knowledge of the subject of the origin of sex, so much as an attempt to express concisely a theory of sex drawn from various sources, but principally from a work on the "Evolution of Sex" by Geddes & Thomson, a work which seems to me to mark an epoch in the science of philosophical biology.

County Parks, T. H. Macbride

Proceedings of the Iowa Academy of Science

The title of this paper would seem to require little definition. By county parks are meant simply open grounds available for public use in rural districts, as are city parks in towns. There is nothing new in the idea; it is simply an effort to call back into public favor the once familiar public "common." This does not, however, refer simply to public land such as government land, to be claimed and plundered by the first comer, nor, indeed, to land to be used by the public indiscriminately at all, but to land devoted to public enjoyment, purely to the …

Notes On Forest Distribution In Iowa, T. H. Macbride

Proceedings of the Iowa Academy of Science

The peculiar character of our American forest geography early attracted the attention of intelligent observers. Civilized men, Frenchmen, crossing the continent from the Atlantic seaboard, after threading for two hundred leagues a forest almost unbroken, suddenly found themselves in the presence of vast treeless plains, extending westward across a large portion of the central Mississippi Valley. In wonder and admiration the voyageur looked upon these great plains, grass-grown and flower-bedecked, and found them counterpart to the green meadows of France; to them he gave the name prairie, a word now so familiar as to have long lost for all English-speaking …

The Anatomy Of Sphaerium Sulcatum Lam., Gilman A. Drew

Proceedings of the Iowa Academy of Science

For a number of years the embryology of the Cyrenidae has been attracting considerable attention, but little has been added to our knowledge of the general anatomy since Dr. Franz Leydig's publication in 1855 (No. 5), who recorded such anatomy as could be made out from young and rather transparent specimens.

A Study Of The Genus Clastoptera, Elmer D. Ball

Proceedings of the Iowa Academy of Science

In the development of the hind tibiae and the structure and venation of the wings, the insects under consideration represent the highest and most specialized forms of the Cercopidae if not of the Homoptera; marking, as Uhler suggests, an important advance toward the Heteroptera in the increased freedom of the anterior coxae and the possession of a terminal membrane to the corium.

Occurrence Of Megalomus Canadensis, Hall, In The Leclaire At Port Byron, Illinois, William Harmon Norton

Proceedings of the Iowa Academy of Science

This common fossil of the Guelph of Canada has not been noted in the Le Claire beds of Iowa, or their immediate extension into adjacent states. Its occurrence, therefore, at Port Byron, Illinois, in the Barrett quarries one and one-half miles north of the town, is of special interest, since it shows a range much further to the west than hitherto observed, and a co-mingling of the Guelph and Niagara faunas in the Le Claire, similar to that in the so-called Guelph of Wisconsin. The specimens are well preserved, casts of the normal type not conforming to the variety of …

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.

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.

On The Geological Position Of Bennettites Dacotensis Macbride With Remarks On The Stratigraphy Of The Region In Which The Species Was Discovered, Samuel Calvin

Proceedings of the Iowa Academy of Science

Since Professor Macbride's paper on Bennettites dacotensis was published in the American Geologist for October, 1803, there have been numerous inquiries respecting the exact geological horizon from which the cycads were derived. The close resemblance and the intimate relationship indicated between the Dakota fossil and Tysonia marylandica Fontaine, while not conclusive, would point toward a common horizon for the two species, and so make it possible to correlate the Potomac formation with a definite Mesozoic horizon in the northwest. Professor Macbride's paper left the stratigraphical position of his species undecided. To settle, if possible, the question definitely the writer recently …

Bacteria, Their Relation To Modern Medicine, The Arts And Industries, L. H. Pammel

Proceedings of the Iowa Academy of Science

It has been customary for the president in making his retiring address, to choose some popular subject and discuss it on broad lines. In some cases my predecessors have given a resume of the scientific literature in our own State, and I need not say that we all feel proud of the work accomplished by this small band of workers. I shall venture, in this address, to discuss the subject of Bacteria along general lines and hope I may be able to correct some popular misapprehensions concerning the subject.
