The Animal Cell In The Light Of Recent Work, Gilbert L. Houser Jan 1903

The Animal Cell In The Light Of Recent Work, Gilbert L. Houser

Proceedings of the Iowa Academy of Science

With the discovery of the centrosome, microscopical work on the animal cell apparently reached its culmination. It was predicted that further study would yield little more than the details of larger facts already known. The last few years have marked the addition of just such details in even greater measure than was imagined; but it is also true that altogether unexpected contributions have been made from work along other than classic microscopical lines. Especially to be mentioned are: (1) the application to the cell of the data and the methods of physical chemistry; and (2) the extension of experimental biology …


A Contribution To Our Knowledge Of The Development Of Prunus Americana, R. Earle Buchanan Jan 1903

A Contribution To Our Knowledge Of The Development Of Prunus Americana, R. Earle Buchanan

Proceedings of the Iowa Academy of Science

There is no field more promising of results and none that has received less attention until recently than the investigation of the more hidden life histories of our cultivated plants. The gross anatomy of these plants has long been studied. Later we learned of their relationships through a study of their grouping and classifications. Lastly, the microscope with all its world of technique has been brought to the study of the various plant structures. The best and most nearly perfect or ideal treatment of our cultivated plants can be attained only when we know all that is possible regarding their …


A Buried Peat Bed In Dodge Township, Union County, Iowa, T. E. Savage Jan 1903

A Buried Peat Bed In Dodge Township, Union County, Iowa, T. E. Savage

Proceedings of the Iowa Academy of Science

Union County already occupies a notable place in the annals of the Pleistocene geology of our State. Near the towns of Thayer and Afton Junction are exposed the gravel beds which first furnished the basis for the separation of the drift of the pre-Kansan age from that of the Kansan, and for the establishment of the Aftonian interglacial interval The name of this latter age of American geology was taken from the town of Afton which is located not far from the above mentioned gravel exposures, in Union county.


Some Features In The Analysis Of Dolomite Rock, Nicholas Knight Jan 1903

Some Features In The Analysis Of Dolomite Rock, Nicholas Knight

Proceedings of the Iowa Academy of Science

The purpose of this work was to compare different methods of determining silica in dolomite, and also to ascertain the amount of magnesium oxalate that will precipitate with calcium oxalate in connection with the analysis of dolomite rock by different students. These rocks abound in Iowa and in many other portions of the United States. The specimens under examination were variable mixtures of calcium and magnesium carbonates, with silica, ferric oxide and aluminum oxide. All were obtained from the Mount Vernon quarry and belonged to the Niagara period of geologic history.
