Presidential Address - Some Problems Of Heredity And Evolution, H. E. Summers Jan 1902

Presidential Address - Some Problems Of Heredity And Evolution, H. E. Summers

Proceedings of the Iowa Academy of Science

Of all biological problems none is of more importance and interest to the mass of mankind than that dealing with the laws of evolution. To the biologist, of course, these laws are of prime importance, as expressing the ultimate result of all life processes. But I refer here rather to the widespread interest among all classes of educated people, due, I believe, to a feeling that as our human civilization is advancing in conformity with these laws, a fuller knowledge of them might enable us the better to guide and control our progress in the future.


Some Observations Upon The Action Of Coherers When Subjected To Direct Electromotive Force, Frank F. Almy Jan 1902

Some Observations Upon The Action Of Coherers When Subjected To Direct Electromotive Force, Frank F. Almy

Proceedings of the Iowa Academy of Science

Most of the earlier quantitative work with coherers seemed to indicate that the coherer was uncertain or indefinite in its action. Some of the more recent work has, however, shown more definite and consistent results.


The Accretion Of Flood Plains By Means Of Sand Bars, Howard E. Simpson Jan 1902

The Accretion Of Flood Plains By Means Of Sand Bars, Howard E. Simpson

Proceedings of the Iowa Academy of Science

About one-half mile above the confluence of the Iowa and Cedar Rivers, the Iowa makes a great bend from a southwesterly to a southeasterly direction. The river on the outerside of this curve is rapidly cutting at the base of a high bluff for a distance of about one-third of a mile. The bluff extends beyond at each end, bounding the flood plain, but at some distance from the stream. The bluff is composed chiefly of Kansan drift overlain by Iowan loess, which creeps rapidly riverward when saturated with water.


Some Ecological Notes On The Vegetation Of The Uintah Mountains, L. H. Pammel Jan 1902

Some Ecological Notes On The Vegetation Of The Uintah Mountains, L. H. Pammel

Proceedings of the Iowa Academy of Science

The Uintah range of mountains extends in a northeasterly direction from the Wahsatch range to Green River in eastern and northeastern Utah. In the range occur types of plants from the southwest, the boreal types of the mountains further northward, many forms from the main Rocky mountain flora, besides prevailing forms west of the continental divide.


The Duck Hawk (Falco Peregrinus Anatum) In Iowa, B. H. Bailey Jan 1902

The Duck Hawk (Falco Peregrinus Anatum) In Iowa, B. H. Bailey

Proceedings of the Iowa Academy of Science

Few birds of the United States are more widely and generally distributed, and probably no one species is more isolated as to the individual pairs than the Duck Hawk, (Falco peregrinus anatum).


Significance Of The Occurrence Of Minute Quantities Of Metalliferous Minerals In Rocks, Charles R. Keyes Jan 1902

Significance Of The Occurrence Of Minute Quantities Of Metalliferous Minerals In Rocks, Charles R. Keyes

Proceedings of the Iowa Academy of Science

The present consideration of the occurrence of many of the more common metals in minute quantities in the rocks had its foundation in an inquiry started by Messrs. Winslow and Roberson, in connection with the investigation of the Lead and Zinc deposits in Missouri, undertaken by the geological survey of that state. Although the work of these authors ended with their general report, the special phases of the investigation were not dropped by the survey. While the later results are by no means complete as yet, owing at that time to circumstances entirely beyond the control of the scientific corps …


Genesis Of Certain Cherts, Charles R. Keyes Jan 1902

Genesis Of Certain Cherts, Charles R. Keyes

Proceedings of the Iowa Academy of Science

As regards origin, the cherts which occur so abundantly throughout the limestones of the lower carboniferous of the Mississippi valley have been the subject of much speculation. The same problem has received attention from every quarter of the globe. While the explanations offered differ very much from one another they in general agree in that they are regarded as formed contemporaneously with the geological formations in which they occur. The writings of Prestwich, Irving, Van Hise, Hull, Benard, Hinde, Hardman, Hovey, and many others corroborate this statement.


The Preparation Of Phenyl Ether, Alfred N. Cook Jan 1902

The Preparation Of Phenyl Ether, Alfred N. Cook

Proceedings of the Iowa Academy of Science

While ethyl ether, the common ether of the modern drug store, has been known for three and a half centuries, and has been used as an anesthetic for over fifty years, phenyl ether is of more recent origin. It has never been put upon the market and has never been put to any so-called "practical use." Improved methods of preparation, however, may bring it within reach of the physiological chemist or the manufacturer, so that this substance or some of its immediate derivatives may, 'ere long, play an important part in the economy of men.
