Is The Appetite Of Swine A Reliable Indication Of Physiological Needs?, John M. Evvard Jan 1915

Is The Appetite Of Swine A Reliable Indication Of Physiological Needs?, John M. Evvard

Proceedings of the Iowa Academy of Science

The pig is farrowed with a fairly definite set of specifications for development all wrapped up in their mystery in a two to three pound bundle of throbbing, active "stuff." And yet before the pig sought the outer life apart from the womb of his dam, these specifications were enclosed in the minutest bit of protoplasm, the impregnate ovum resulting from the union of two germ cells, one from the male and the other from the female.

On The Lymphatic System Of The Common Rat, Thesle T. Job. Jan 1915

On The Lymphatic System Of The Common Rat, Thesle T. Job.

Proceedings of the Iowa Academy of Science

From fifty injected specimens, the gross anatomy of the Common Rat has been studied and outlined. The results of the work have further proven the studies of McClure and Silvester on the Lymphatico-venous communications in the Jugulo-subclavian district, and of Silvester on the renal vein communications, and have established two additional communications, the portal vein connection and the ilio-lumbar vein connection. The main circulation and disposition of the lymphatic system has been determined and the need of further knowledge concerning the histology of the lymph nodes, of which there appear to be two types, is pointed out.

Leaching Of The Pleistocene Drifts Of Eastern Iowa, Morris M. Leighton Jan 1915

Leaching Of The Pleistocene Drifts Of Eastern Iowa, Morris M. Leighton

Proceedings of the Iowa Academy of Science

The term leaching is applied by glaciologists to that process of dissolving and carrying out in solution by ground water the soluble constituents of the drift, of which lime carbonate is the most notable in the Mississippi Valley. This discussion of that phenomenon is based on observations made by the writer on Pleistocene deposits of the larger part of the east half of Iowa, and in the vicinity of Chicago, Illinois.

Snakes Swallowing Their Young, E. D. Ball Jan 1915

Snakes Swallowing Their Young, E. D. Ball

Proceedings of the Iowa Academy of Science

Doctor Herrick in his review of the "Infancy of Animals" in a recent number of Science raises the question of the accuracy of observations on snakes swallowing their young. As the writer once had what was probably a particularly favorable opportunity to witness this phenomenon, it occurs to him that the following facts may be worth recording.

Notes On The Distribution Of The Prairie Spotted Skunk In Iowa, B. H. Bailey Jan 1915

Notes On The Distribution Of The Prairie Spotted Skunk In Iowa, B. H. Bailey

Proceedings of the Iowa Academy of Science

In 1906 the U. S. Department of Agriculture published faunal bulletin No. 26 by Arthur H. Howell, Assistant Biologist of the U. S. Biological Survey on the "Revision of the Skunks of the Genus Spilogale". According to this report the only species referred to Iowa is Spilogale interrupta Raf., three specimens of which were examined from this state; one of which came from Gladbrook, and two from Marshalltown. His distributional map shows the range of this species as extending to southeastern Minnesota on the following statement by Mr. E.T. Seton "He (E. T. Seton) states that two were killed by …

The Building And Function Of The College Museum, B. H. Bailey Jan 1915

The Building And Function Of The College Museum, B. H. Bailey

Proceedings of the Iowa Academy of Science

It is with a keen sense of how far short of the real mark he shall come that the writer aims at the center of this target. It is also with an appreciation of the situation in the average college with regard to meager funds, limited space, lack of appreciation by the authorities as well as the public, and the frequent unpreparedness along museum lines and the overworked condition of the professor of natural sciences.

Macroscopic Fuana Of A Small Brook, D. M. Brumfiel Jan 1915

Macroscopic Fuana Of A Small Brook, D. M. Brumfiel

Proceedings of the Iowa Academy of Science

The brief paper here presented is but the first of a series of studies which the writer proposes to work out concerning the ecological relations of the animal life of Johnson County. Johnson County has been chosen as the field for observations for several reasons, among which are its availability from Iowa City and the University buildings as a center, its wealth of diversified habitats, and the most excellent work already done by Professor Bohumil Shimek in the field of plant ecology, upon which all studies of animal ecology depend, as all animals ultimately depend upon plants for food.

Illuminating Power Of Kerosenes Used In Iowa, William Kunerth Jan 1914

Illuminating Power Of Kerosenes Used In Iowa, William Kunerth

Proceedings of the Iowa Academy of Science

The kerosene oil industry in the United States dates back to about the year 1850, although evidences are found in the oil producing regions of Pennsylvania which indicate that the existence of the oil was known long before that date.

Sex-Linked Factors In The Inheritance Of Rudimentary Mammae In Swine, Edward N. Wentworth Jan 1914

Sex-Linked Factors In The Inheritance Of Rudimentary Mammae In Swine, Edward N. Wentworth

Proceedings of the Iowa Academy of Science

Characters fall into four classes when related to sex. The first type is represented by horns in cattle, and red, black and white coats in swine, their appearance being entirely independent of sex. At the opposite extreme are those characters that are confined to one sex only, as the male plumage of the Brown Leghorn or pheasant. Similarly, although exhibiting different behavior somatically, are characters like mammae or tusks that exist in a rudimentary condition, or at least a relatively undeveloped condition, in one sex. Characters of this sort are intimately related to the sex glands and removal of the …

The Coleoptera Of Henry County, Iowa, Inez N. King Jan 1914

The Coleoptera Of Henry County, Iowa, Inez N. King

Proceedings of the Iowa Academy of Science

The members of the order Coleoptera can be distinguished readily from all other insects, except the earwigs, by the horny, veinless wing-covers which meet in a straight line down the back, beneath which there is a simple pair of membraneous wings. Beetles differ from earwigs mainly in not having the pincer-like appendages at the tail-end of the body, characteristic of the earwigs.

Some Factors Affecting Fetal Development, John M. Evvard Jan 1913

Some Factors Affecting Fetal Development, John M. Evvard

Proceedings of the Iowa Academy of Science

That the nourishment of the mother during the period of gestation should affect the weight, vigor, general relative size, bone and skin (with covering) of the offspring is quite evident from the results of some recent experimental studies made by us. Dr. A.W. Dox and S.C. Guernsey of the Chemical Section arc working upon the chemistry of this problem in co-operation with the writer. Our work is being carried on with both sheep and swine in order that we may get a double set of records upon different species of animals.

Food Habits Of The Skunk, Frank C. Pellett Jan 1913

Food Habits Of The Skunk, Frank C. Pellett

Proceedings of the Iowa Academy of Science

In observation of the food habits of the birds of prey one can take advantage of the fact that food must be brought to the young in the nest. With the skunk, which is a nocturnal animal, many difficulties present themselves in gathering sufficient information on which to base a conclusion, and it must be confessed in the beginning that the results are rather of a negative than a positive character. Animals in captivity adapt themselves to their environment quickly and form habits which perhaps might not be normal when living under natural conditions. In making the observations on this …

Color Inheritance In The Horse, Edward N. Wentworth Jan 1913

Color Inheritance In The Horse, Edward N. Wentworth

Proceedings of the Iowa Academy of Science

While laboratory animals have yielded very nicely to the study of their inheritance of color, the horse still remains a mystery in many of the phases of coat transmission. Hurst and Bunsow have recognized chestnut with the sorrel and liver shades as a true recessive, and Hurst has shown black to be epistatic to this reddish pigment. Bays and browns have been with difficulty separated but have been considered as epistatic to both colors mentioned, while grays and roans seem dominant to the entire series of color. One difficulty which seems to have beset all investigators up to the present …

Mounds And Mound Explorations In Northeastern Iowa, Ellison Orr Jan 1913

Mounds And Mound Explorations In Northeastern Iowa, Ellison Orr

Proceedings of the Iowa Academy of Science

Prehistoric earthworks are common in Allamakee, Clayton and Winneshiek Counties, in the north eastern corner of Iowa, on the bluff tops and on the terraces of the Mississippi and its tributaries, the Oneota or Little Iowa, and the Turkey. They are always close to the stream along which they occur, none being found in such position that some part of the river cannot be seen from them, none being over a mile from the water and usually very much nearer.

A Case Of Urticaria Factitia Observed In The Coe College Psychological Laboratory, W. S. Newell Jan 1913

A Case Of Urticaria Factitia Observed In The Coe College Psychological Laboratory, W. S. Newell

Proceedings of the Iowa Academy of Science

Record of an unusual affection which appeared in experimental work in tactual space. In submitting the following record upon a case of Urticaria, the writer has intentionally observed two restrictions, (1) to leave the technical discussion of the disease in question to medical treatises, (2) to avoid unwarrantable generalization from a single case under observation. While conforming with these limitations, it has seemed that a record of the case, giving such concrete details of the appearance, the progress and the peculiarities of the disease as it was studied in our laboratory, might leave deductions and generalizations to await the discovery …

The Effect Of Smoke And Gases Upon Vegetation, A. L. Bakke Jan 1913

The Effect Of Smoke And Gases Upon Vegetation, A. L. Bakke

Proceedings of the Iowa Academy of Science

The history of an industrial community marks itself into three divisions: (1) the movement from the country into the city, (2) the building up of enterprises or commercial concerns, (3) the conservation of waste products. The movement of the people from the country to the city carries with it a number of problems. Many of these would not be met with in the country.

Segregation Of Fat Factors In Milk Production, F. B. Hills, E. N. Boland Jan 1913

Segregation Of Fat Factors In Milk Production, F. B. Hills, E. N. Boland

Proceedings of the Iowa Academy of Science

The need of an investigation into the problem of inheritance of fat in milk, has long been recognized by the practical milk producer and the physiologist. For the former, a solution of the problem would simplify, very markedly, his breeding operations, as well as increase the certainty of his results. For the latter, a knowledge of the fat producing possibilities of the animal genetically would give an index to the physiological limits of fat formation, and its relation to metabolism.
