The Vascular Supply Of The Teeth Of The Domestic Cat, C. C. Nutting

Proceedings of the Iowa Academy of Science

After all that has been written about the anatomy of the domestic cat it would seem a hopeless task to find any facts of real importance in a field so carefully gleaned by Wilder and Gage and a host of other writers of the past and present.

Laboratory Notes In Zoology, Herbert Osborn

Proceedings of the Iowa Academy of Science

It is my purpose, in these notes, to call attention to some matters of experience in laboratory work which may be of service to other teachers and also to place on record the results of some studies by students that appear to be worthy of preservation. Laboratory work in zoology has been carried on at the Agricultural College since 1876, and for nearly all of that time under my own supervision, so that while my own specialty has kept me busy in other lines some notes from the experience of these years may be of service to teachers who may …

The Johns Hopkins Biological Laboratory, W. S. Windle

Proceedings of the Iowa Academy of Science

For the past fifteen years it has been customary for the members of the biological department of Johns Hopkins University to devote their summer vacations to pursuing their studies upon the sea shore, where living marine animal forms may be secured for daily use.

Additions To The Known Species Of Iowa Ichneumonidae, Alice M. Beach

Proceedings of the Iowa Academy of Science

The list herewith presented embraces those species taken in Iowa which are not recorded in the Catalogue of Iowa Animals, prepared by Prof. Herbert Osborn and published in 1892.

Preliminary Observations On A Cattle Disease Frequently Occurring In Iowa, W. B. Niles

Some Reasons Why Frogs Are Able To Survive, Gilman Drew

Proceedings of the Iowa Academy of Science

The Leopard frog (Rana halecina, Kahn) and allied species occur in considerable numbers and have a wide geographical distribution. Being entirely defenseless, beset by enemies at every turn-fish, reptiles, birds and mammals-as well as being cannibals among themselves, subject to many diseases and the hardships of great extremes of temperature, they are, withal, able to maintain their numbers.

President's Address, C. C. Nutting

Proceedings of the Iowa Academy of Science

What we have been doing:- In choosing a subject upon which to address you on this occasion, it occurred to me that it might be profitable to present briefly as possible, the work done by the individual members of the Academy, aside from the papers presented before this body.

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

Proceedings of the Iowa Academy of Science

About two months ago the chairman of this committee sent a circular letter to all the members of the Academy asking for notes that could be used in this report. Up to the time of writing, December 19th, only one member has responded to this request, giving an interesting note concerning one species of animal new to the State, and a note concerning the disappearance of the beaver from Big Creek, Tama County.

Significance Of The Concealed Crests Of Fly Catchers, C. C. Nutting

Proceedings of the Iowa Academy of Science

In all the works on animal coloration that have come under my observation, there is a marked absence of any attempt to account for the concealed crests of bright colors on the crown of many birds, notably the Tyrannidae or "Fly-Catchers."

The Key For The Identification Of The Weed Seeds Found In Clover Seed, F. C. Stewart

Proceedings of the Iowa Academy of Science

The identification of weed seeds, though an important matter, is not an easy one. The average person knows Fox-tail, and probably that is about all. Even botanists, who have not given the subject special attention, will be surprised to find how small a number of weed seeds they are able to identify without study.

Some Of The Causes And Results Of Polygamy Among The Pinnipedia, C. C. Nutting

Proceedings of the Iowa Academy of Science

Several years ago the writer was much struck by the great sexual differences met with among the Gallinae, and had noted the fact that there was a relation between sexual disparity in size and polygamy.

Notes On The Redrock Sandstone, Charles R. Keyes

Proceedings of the Iowa Academy of Science

The sandstone of Redrock, in Marion County, Iowa, has long attracted popular attention. The bright vermillion cliffs rise to a height of one hundred to one hundred and fifty feet above the water surface of the Des Moines River. The red coloration of the rock, however, is (?). The formation has a known geographic extent of at least twenty miles; and probably stretches out much farther. At Redrock Cliff the stone is massive for the most part, but rather soft and thin-bedded above. At this place it is a very fine grained and homogeneous sand rock, some portions even affording …

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, …

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 …

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

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.

Aboriginal Rock-Mortars, H. L. Bruner

Proceedings of the Iowa Academy of Science

A few notes by the writer, under the above title, were published in the American Anthropologist for October, 1891. These "mortars", excavated in rock in situ, are located on the east slope of the Franklin Mountains, about eleven miles north of El Paso, Texas, and near the mouth of the ''House Canon."

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.

Systematic Zoology In Colleges, C. C. Nutting

Proceedings of the Iowa Academy of Science

A few months ago one of the curators of the Smithsonian Institution took occasion, in private conversation, to complain of the fact that our universities and colleges did not turn out men capable of taking hold of a collection of zoological specimens and working it up systematically. He said: "We can find plenty of students from Johns Hopkins, Harvard, the University of Pennsylvania, etc., who can do good work if they are put to investigating the embryology of a single species, or writing a thesis on the histology of certain organs. But we have great difficulty in finding men who …

Oviposition Of Anomalon Sp., C. P. Gillette

Proceedings of the Iowa Academy of Science

While passing an apple tree August 18, on which were a brood of Datana ministra larvae about one-third grown, my attention was attracted by the presence of a large Hymenopterous parasite busily ovipositing in their soft bodies and apparently much to their discomfort. The parasite was a large black Anomalon sp. not in my collection, unless, possibly, it is a variety of A. pallitarse Cress. It differs from Cresson's description by having its middle and hind pairs of legs entirely black and its face and antennae entirely yellow.

The Native Food Fishes Of Iowa, Seth E. Meek

Proceedings of the Iowa Academy of Science

In the waters of Iowa, including the Mississippi River along her eastern border, are found about one hundred species of fishes, of these about thirty-six are usually found in our markets, and are regarded as food fishes of more or less value.

Local Problems In Science, Herbert Osborn

Proceedings of the Iowa Academy of Science

It may be said, with truth, that Science knows no boundaries of geography, polities, sect or race. That if there is to her credit, any characteristic of performance, it is that of universality.

Directive Coloration In Animals, J. E. Todd

Proceedings of the Iowa Academy of Science

The paper was the outgrowth of observations made on the Western plains. It is published in full in the American Naturalist for 1888. While recognizing the validity of protective, ornamental and typical coloration, as defined by Darwin, Wallace, Belt and others, the writer claimed that a very considerable amount of coloration in animals remained unexplained.

Animal Intelligence, H. W. Parker

Proceedings of the Iowa Academy of Science

So far as evolution is concerned, it really matters little' at what point intelligence appears. Intelligence proper includes the reasoning power as its chief and distinguishing characteristic. Facts regarded as proving a degree of this power in animals were reviewed in detail, and shown to be susceptible of a lower interpretation in harmony with the general phenomena of animal life.
