Iowa Erysiphaceae, J. P. Anderson

Proceedings of the Iowa Academy of Science

The Erysiphacere are popularly known as blights, white or powdery mildews. They are parasitic on quite a large variety of plants and during the summer are often quite conspicuous factors of the vegetation, covering the leaves or other parts with a white mycelium which sometimes gives the host an almost hoary appearance.

Some Features Of Iowa Ground Waters, W. S. Hendrixson

Proceedings of the Iowa Academy of Science

About ten years ago the Iowa Geological Survey published an elaborate Report on Iowa Artesian Wells by Professor William H. Norton of Mt. Vernon. In this Report, which occupies most of Vol. VI of the Survey, are published the analyses of about fifty deep well waters. The geology of these wells and other deep borings was fully discussed, and illustrated.

The Innervation Of The Lateral Line System Of Amphiuma, H. W. Norris

Proceedings of the Iowa Academy of Science

Kingsbury has given us an account of the general distribution of the sense-organs of the lateral line system in Amphiuma. According to him the arrangement in this form is almost typical of Amphibia. On the head: the supra-orbital group dorsal to the eye extends anteriorly to the tip of the snout; the infra-orbital group runs from the angle of the mouth ventral to the eye to the snout region; the oral line on the lower jaw passes along the lower lip; an angular series connects the oral with the infra-orbital; the gular series is found on the ventral surface of …

Presidential Address - Influence Of Modern Science In The Formation Of Ideals, C. O. Bates

Proceedings of the Iowa Academy of Science

Allow me to congratulate you on the completion of another year's successful and profitable work. Self-imposed scientific effort brings its own reward to every earnest soul in search of truth. The acquisition of new knowledge is both fascinating and stimulating. In proportion as we get knowledge at first hand, just in that proportion is the fascination and the stimulation increased, and our acquirements become a part of our being.

Homology Of Tissues Of Ferns, Henry S. Conard

Proceedings of the Iowa Academy of Science

In comparing two or more organisms our standpoint may be developmental, morphological or physiological. Or, we may strike a middle ground in what is called the morpho-physiological point of view.

Studies In Karyokinesis, James Ellis Gow

Proceedings of the Iowa Academy of Science

The work whose results are here presented has been done at various times and places. The investigation of Trillium was undertaken at Blairstown during the fall and winter of 1905, and was carried on in the Botanical laboratory of the Blair Academy. Indian Corn and Arisaema were studied during 1901 and 1902 at the State University of Iowa, under the personal direction of Prof. T. H. Macbride, to whom are due thanks for the first suggestion leading to the undertaking, and for continued advice and assistance.

The Determination Of Silica, Nicholas Knight

Proceedings of the Iowa Academy of Science

The method of procedure depends upon the amount in the substance under investigation and also upon the condition of the silica, whether in the form of sand, or as a soluble or an insoluble silicate. The determination is beset with difficulties, but these are by no means insurmountable. It has been the object of much careful study and investigation and very accurate results are attainable even by persons who have not had much experience in quantitative analysis.

Some Features Of The Channel Of The Mississippi River Between Lansing And Dubuque, And Their Probable History, Samuel Calvin

Proceedings of the Iowa Academy of Science

The courses followed by the major streams of the interior of the North American continent during Paleozoic and Mesozoic times, cannot now be pointed out with any high degree of certainty. The numerous upwarps and twistings to which the continental ridge was subjected, caused large portions of what is now North America to be at times above the sea, at other times below, and the drainage was shifted from area to area, from one direction to another. During a period as recent as the late Cretaceous the drainage of the middle Northwest flowed westward into a great sea that overlapped …

Physiographic Significance Of The Mesa De Maya, Charles R. Keyes

Proceedings of the Iowa Academy of Science

The Mesa de Maya is a small elevated tableland lying on the borders of Colorado and New Mexico, between Trinidad and Raton. It has an elevation of over 9,000 feet above sea-level and about 3,600 feet above the valleys on either side.

Tertiary Terranes Of New Mexico, Charles R. Keyes

Proceedings of the Iowa Academy of Science

Deposits of Tertiary age are extensively developed in New Mexico. The greatest thicknesses are found in the northwestern and central parts of the state, where their maximum measurements reach no less than 3,000 feet. Many minor areas are also known. These deposits recline usually in marked unconformity upon the beveled edges of the Cretaceous and older strata. They are geologically among the most important deposits of the region.

Volcanic Phenomena About Citaltepetl And Popocateptl, Charles R. Keyes

Proceedings of the Iowa Academy of Science

Two noble mountains fired the fancies of the native races of Mexico before the Aztecs. Quiescent at present they were within historic time quite active. They are the "'Star Mountain," or Citlaltepetl, and the "Smoking Mountain" or Popocatepetl. Both tower above the great Mexican tableland, itself 7,000 feet above tide-level; the first named on its eastern margin and the last mentioned in the central part overlooking the capital city.

Exposures Of Iowan And Kansan (?) Drift, East Of The Usually Accepted West Boundary Line Of The Driftless Area, Ellison Orr

Proceedings of the Iowa Academy of Science

McGhee, in the map accompanying his Pleistocene History of Northeastern Iowa, makes the "Upper Till" overlap the "Lower Till." And the eastern boundary line of the "Upper Till" (Iowan), as shown by the same, and consequent western boundary line of the Driftless Area, in the counties of Winneshiek, Allamakee and Clayton, the three northeastern counties of Iowa, begins at the boundary line of Clayton County about six miles south of the mouth of the Turkey River, and runs thence northwesterly at about that distance south of the Turkey, to West Union in Fayette County, and from there runs nearly due …

Effects Of Certain Characteristics Of Rocks On Their Erosion, J. E. Todd

Proceedings of the Iowa Academy of Science

A study of the streams of the western slope of the Missouri Valley in South Dakota and northern Nebraska presents some striking contrasts. These are the more notable because the histories of the streams since the Tertiary have been much the same. At the opening of the Pleistocene, their courses were uniformly eastward from the mountains on the west to the master stream in the James River Valley. The Glacial Period resulted in the shifting of the latter westward to the present line of the Missouri above Yankton and it rapidly cut down to a grade of about one foot …

An Attempt To Illustrate Tides And Tidal Action, John L. Tilton

Proceedings of the Iowa Academy of Science

The inspiration for this paper was due to Professor W. M. Davis, who, in an article published in the Journal of School Geography, Vol. 4, No. 7, discussed the "Illustration of Tides and Waves". This led me to think that here in an inland town where there is no opportunity for the student to observe tidal effects, there is a need for class illustration that I, at least, had been neglecting. I consequently drew a plan of what it seemed to me would meet the need and employed a local tinner to construct the apparatus. The piece proves very satisfactory …

The Disparity Between Age And Development In The Human Family, Illustrated By Pronounced Cases Due To Thyroid Malformations., James Frederic Clarke

Proceedings of the Iowa Academy of Science

The author of Rip Van Winkle has his hero awaken from the long sleep, an old man. The writer does not violate in fiction our conception of the uniform advancement, in human growth and development, from infancy to old age. So uniform is growth in children that we associate in our minds rather definite sizes and mental conditions with certain years from birth. Dress patterns are made for a three or an eight year old girl. A shoe merchant can usually select correct shoes for your boy if he is told the age. There is not great variation from the …
