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,
