The Total Solar Eclipse Of May 28, 1900 (Observed At Wadesboro, N.C.), David E. Hadden Jan 1900

The Total Solar Eclipse Of May 28, 1900 (Observed At Wadesboro, N.C.), David E. Hadden

Proceedings of the Iowa Academy of Science

A total eclipse of the sun is always one of the grandest and most awe-inspiring of all natural phenomena. To the superstitious and unenlightened people of India, Africa and the islands of the sea it is a phenomenon full of terror because of the belief that some great hideous monster is devouring the orb of day, but to the astronomer and scientist it is of such interest and importance that governments, colleges, societies and individuals send out expeditions equipped with costly instruments, over land and sea —literally to the ends of the earth — to locate within the track of …

Presidential Address - The Social Service Of Science, William Harmon Norton Jan 1900

Presidential Address - The Social Service Of Science, William Harmon Norton

Proceedings of the Iowa Academy of Science

The extent to which society may be considered as an organism is still, I understand, a matter of controversy with sociologists. But without awaiting its adjudication, we may surely make use of a simile as ancient as that of the Apostle who spoke of individual Christians as members of one body, or as that of the wise old Roman, who taught the mutinous plebs the parable of the body politic, all of whose members were nourished by the well-fed patrician belly, and consider together this evening the social function of science in the body social.

A Study Of A Contaminated Water Supply, J. B. Weems, J. C. Brown Jan 1900

A Study Of A Contaminated Water Supply, J. B. Weems, J. C. Brown

Proceedings of the Iowa Academy of Science

A pure water supply is one of the most valuable possessions which nature can give to any community. The value of a pure water supply is realized more readily by those who live in a city or town where the population is concentrated than by those living in the country where the families are isolated.

A Method Of Isolating And Counting Gas Producing Bacteria In Milk, C. H. Eckles Jan 1900

A Method Of Isolating And Counting Gas Producing Bacteria In Milk, C. H. Eckles

Proceedings of the Iowa Academy of Science

It is a well-known fact that more or less gas producing bacteria are present in almost all ordinary milk. The number present varies with the season of the year and the treatment the milk has received.

The Fagaceae Of Iowa, T. J. Fitzpatrick, M. F. L. Fitzpatrick

Proceedings of the Iowa Academy of Science

The oak family comprises five genera and 375 species. The family is of wide geographical distribution, and from an economic point of view, of very great value. Four genera occur in the United States, namely, Fagus (the Beech), Castanea (the Chestnut), Quercus (the Oak), and Castanopsis. The number of species and varieties recognized is 87. Of this number 82 belong to the genus Quercus, one each to Fagus and Castanopsis, and three to Castanea. The only genus indigenous to Iowa is Quercus, the oak, and the number of species recognized is 15.

Pure Food Laws, C. O. Bates Jan 1900

Pure Food Laws, C. O. Bates

Proceedings of the Iowa Academy of Science

The demand for cheap goods and the intense strain produced by commercial competition has induced many dealers and manufacturers to adulterate their products. This practice enables them to satisfy the buyer and outwit their competitors, not to speak of the immediate financial advantage.

A Combination Of Chromic Acid, Acetic Acid And Formalin As A Fixative For Animal Tissues, H. W. Norris Jan 1900

A Combination Of Chromic Acid, Acetic Acid And Formalin As A Fixative For Animal Tissues, H. W. Norris

Proceedings of the Iowa Academy of Science

That many of the fixing reagents in common use in the preparation of tissues for histological study are poorly adapted to the fixation of the ova and embryos of Amphibians, is evident to anyone who gives more than casual attention to the matter. The large amount of yolk present in the cells of the Amphibian embryo makes completely uniform fixation with some reagents impossible, and then, too, the disintegrating effect of many fixing fluids upon the yoke granules makes the result very unsatisfactory. A fluid that gives good fixation is likely to interfere with subsequent staining, as witness most of …

Notes On The Time Of Sexual Maturity In Certain Unios, H. M. Kelly Jan 1900

Notes On The Time Of Sexual Maturity In Certain Unios, H. M. Kelly

Proceedings of the Iowa Academy of Science

In the course of a recent study of the parasites of the Unionidae, the following data in regard to the time of sexual maturity in certain species, and their method of carrying their glochidia, were obtained. This primary inquiry involved the microscopical examination of the sexual glands of each individual. And in females whose gills were found swollen with the sexual product, the portion of these organs forming the marsupium and the stage of development of its contents, were also noted.

Shrubs And Trees Of Madison County, H. A. Mueller Jan 1900

Shrubs And Trees Of Madison County, H. A. Mueller

Proceedings of the Iowa Academy of Science

Madison County is considered a prairie county, yet fully one-fourth of its area is covered with shrubs and trees of some description. The county is traversed from the west to the east by three medium-sized streams, North River, Middle River, and Clanton Creek; thus it is known as the "Three-river country." North River, with its two larger tributaries, North Branch and Cedar Creek, is situated in the north half of the county. The principal timber areas along these streams are in Douglas, Jefferson, and Union townships. Middle River flows through the central part, while its largest tributary, Clanton Creek, flows …

The Morphology And Function Of The Amphibian Ear, H. W. Norris Jan 1900

The Morphology And Function Of The Amphibian Ear, H. W. Norris

Proceedings of the Iowa Academy of Science

In the struggle for existence as individuals the Amphibians, or Batrachians, seem to have a minor position. For the most part of insignificant size, with poorly protected bodies, and with retiring and inoffensive habits, these forms which we know as toads, frogs and salamanders, seem to be poorly adapted to maintain their species. From what the paleontologist tells us, we may well believe that the Amphibians as a class arose, flourished, and then declined to their present insignificant proportions long ago. It is because of the relationships of this group that it is of profound interest to science. It forms …

Preliminary List Of The Flowering Plants Of Adair County, James E. Gow Jan 1900

Preliminary List Of The Flowering Plants Of Adair County, James E. Gow

Proceedings of the Iowa Academy of Science

The collections on which this report is based were made chiefly during the summer of the year 1900, some of the work, however, having been done some years earlier. It is the hope of the author that he may in the course of time be able to supply a complete account of the flora of the county —one which will be exhaustive to the last detail. Heretofore such an undertaking has not been possible for him. The work has been done in the intervals of other work and has taken into account chiefly the more common species. It is here …

Betulaceae Of Iowa, T. J. Fitzpatrick, M. F. L. Fitzpatrick Jan 1900

Betulaceae Of Iowa, T. J. Fitzpatrick, M. F. L. Fitzpatrick

Proceedings of the Iowa Academy of Science

The Birch family as now understood, comprises six genera and about seventy-five species, mostly natives of the northern hemisphere. Some authors include this family with the Oak or Beech family under the name of Cupuliferae. The chief distinction is the arrangement of the pistillate flowers. The Birch family has the pistillate flowers in aments while the Oak family has the pistillate flowers subtended by an involucre which becomes a bur or cup in fruit.

Notes On The Early Development Of Astragalus Caryocarpus, F. W. Faurot Jan 1900

Notes On The Early Development Of Astragalus Caryocarpus, F. W. Faurot

Proceedings of the Iowa Academy of Science

While a student at the University of Nebraska the writer became interested in plant embryology, a subject which has attracted much attention during the past few years, especially since the remarkable work of Strasburger, Guignard, and other European botanists. Many American botanists, however, have since done much work along embryological and cytological lines, viz.: Chamberlain, Webber, Schaffner, Harper, Coulter, and others. Most of the work that has been done is of a purely technical and botanical character, excepting that done in the U. S. Department of Agriculture, where it has been carried on especially with reference to fertilization and its …

Notes On The Bacteriological Analysis Of Water, L. H. Pammel Jan 1900

Notes On The Bacteriological Analysis Of Water, L. H. Pammel

Proceedings of the Iowa Academy of Science

The recent epidemic of typhoid fever at the college is of interest to us and especially the methods now in vogue with reference to the examination of water for various organisms. During the recent epidemic and previously the well waters in the vicinity of Ames as well as the college water supply were examined at various times. An examination has also been made of water coming from wells of the parties who have furnished milk to the college. It should be stated here that this report is not completed owing to the fact that some of the species have not …
