Salmonella And Paracolon Species Isolated From The Wild Brown Rat, Rattus Norvegicus, In The City Of Richmond, Virginia, John Miles Sharpley

Master's Theses

The importance of bacteria as a cause of serious intestinal diseases in man and. other animals has been recognized since the early days of the science of bacteriology. Of those forms usually associated with intestinal disturbances in man, the species considered most important are those belonging in the Salmonella group, the Paracolon group, and the Shigella group. Also, it has been known since the early part of this century that the conman rat serves as an important vector for the dissemination of infectious organisms. For example, standard textbooks list rats as primary vectors of enteric bacteria. However. there has been …

Note On The "Leopoldina," Or "The Imperial German Academy Of Naturalists At Halle", S. W. Geiser

Field and Laboratory

Recently, a professor of entomology sent an urgent letter of inquiry relative to the association of German naturalists called, in the older writings, the "Leopoldina," or, more fully, the "Academia Caesarea Leopoldino-Carolina Naturae Curiosorum." He had read an account of Jacob Boll, early Texan naturalist, and therein had noted his election (March 1, 1873) to membership in the society. The article stated that, in 1873, the Academy had its seat at Dresden, where its Praeses, Heinrich Gottlieb Ludwig Reichenbach had been for many years professor of natural history, and director of the natural history museum. It also stated, mistakenly, that …

Studies On The Parasitic Helminths Of The North Central States. Ii. Helminths Of Voles (Microtus Spp.) Preliminary Report, Robert L. Rausch, Jack Tiner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The helminths of North American mouse-like rodents have received little study. Previous work has been based on low numbers of animals examined, and there has been little reference to the ecology involved. The purpose of this paper is to present data resulting from the examination of over 600 voles, with special reference to host-parasite relationships

Evidence For A Tryptophane Cycle In Neurospora, Francis A. Haskins, Herschel Mitchell

Department of Agronomy and Horticulture: Faculty Publications

The work of Snell on lactic acid bacteria provided the first evidence that anthranilic acid may act as a precursor to tryptophane in vivo. Since the strains of bacteria which utilize anthranilic acid in the place of tryptophane also use indole, it was not possible to establish the order in which these two precursors occurred. In 1943 Tatum, Bonner and Beadle found that anthranilic acid was accumulated in the culture medium by a Neurospora crassa mutant, strain 10575, which required either tryptophane or indole for growth. It was therefore indicated that anthranilic acid is a precursor to indole in …

Biographical Note On Dr. Ferdinand Rugel, American Botanist, S. W. Geiser

Field and Laboratory

Ferdinand Rugel was one of the most interesting, but least known, of the botanists who worked in the southern United States before the Civil War. A German pharmacist deeply interested in botany, he came to Virginia from Switzerland in 1840. His plan was to collect plants, insects, and mollusks for R. J. Shuttleworth, a British botanist long a resident of Bern. At first Rugel intended to spend only a few years in the botanical exploration of the Southern Appalachians. In 1845, however, he married in eastern Tennessee (where he had fixed his residence), and here he remained the rest of …

Studies On The Parasitic Helminths Of The North Central States. I. Helminths Of Sciurida, Robert L. Rausch, Jack Tiner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

It is accepted that a fair degree of completeness is being achieved in our knowledge of North American mammals and birds. It can be assumed that nearly all the described species of the higher vertebrates are parasitized by helminths, but many of these helminths probably remain undescribed, and little is known of their geographical distribution. Very little information is available on the incidence of the parasites, or their effect on the host.

Dendrouterina Botauri N. Sp., A Cestode Parasitic In Bitterns, With Remarks On Other Members Of The Genus, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A single cestode belonging to the genus Dendrouterina Fuhrmann, 1912, was taken from the small intestine of a least bittern, Ixobrychus e. exilis (Gmelin), collected by the writer on May 31, 1945, at Buckeye Lake, Ohio. Considerable difficulty was experienced in obtaining adequate material of this cestocde, although bitterns were collected in Ohio, Michigan, Wisconsin, and Manitoba. A second infected bird, an American bittern, Botaurus l. lentiginosus (Monatgu), was collected on April 24, 1947, at Horicon Marsh, Wisconsin. Three specimens of Dendrouterina were obtained from this bird.
Unfortunately, since refrigeration was not available in the field, the scolices of all …

The Vetches And Pea Vines (Vicia And Lathyrus) Of Texas, Lloyd H. Shinners

Field and Laboratory

In technical keys, the genus Lathyrus . is characterized as having a squarely truncate stamen tube and styles hairy near the apex on the inner side only, while Vicia has an obliquely truncate stamen tube and styles hairy on the back or all around. These differences are neither well-marked nor easy to see, especially in most Texas species, which have very small flowers. For convenience the species of both genera are here treated together in a single key.

Brief Short-Title List Of Published Works On The History Of Science, Samuel W. Geiser, Bessie T. Geiser

Field and Laboratory

The present brief list was compiled primarily for the use of students in a course on the History of Science offered by the senior author at Southern Methodist University. It is far from complete: scholars conversant with the field will note omission of works they consider of primary importance, and the inclusion of others, to them of secondary interest. We are not sure that in every case our omissions and inclusions are fully defensible; but it is believed that this bibliography includes a very large proportion of the best works on the subject in hand.

A Comparison Of The Autonomic Nervous System Of The Cat And The Pigeon, William P. Mccarthy

Bachelors’ Theses

The purpose of this thesis is to describe the autonomic nervous system of the cat and pigeon and to compare them as to their structure. This comparison will consist in noting the differences and points of similarity between the two animals. The autonomic nervous system of the cat is more complex than that of the pigeon and for that reason the comparison will consist in pointing out the parts of the autonomic nervous system present in the cat, but which are not found in the pigeon. In noting the points of similarity only the most important will be treated.

George Washington Curtis And Frank Arthur Gulley: Two Early Agricultural Teachers In Texas, S. W. Geiser

Field and Laboratory

The death, on September 18, 1945, in Oklahoma City, of Professor George W. Curtis, removed the last of the pioneer teachers of scientific agriculture at early Texas Agricultural and Mechanical College. Professor Curtis' term of service extended over a decade-from 1883 to 1893. He was the third professor of agriculture in the history of the College (having been preceded by Carlisle P. B. Martin and Charles C. Georgeson), and second Director (1890-93) of the Texas Agricultural Experiment Station. With him was closely associated as first Director of the Texas Station, Frank Arthur Gulley (1851-1938), graduate (1880) of the Michigan Agricultural …

Bulletin No. 319 - Cherry Rootstocks, Francis M. Coe

UAES Bulletins

This paper reviews the history and status of the cherry rootstocks problem in Utah and the United States and reports 14 years' results from a sweet cherry rootstocks test orchard on open porous soil at Farmington, Utah.

Although a majority of authorities favor or recommend the mazzard root for sweet cherries, the mahaleb is also widely used and preferred by many nurserymen and growers. Many authorities condemn mahaleb stocks as being dwarfing and short lived. Two orchard tests on heavy soils in the Atlantic states decisively favor mazzard.

In the Utah test orchard, the trees on mahaleb proved to be …

Notes On The Trematode Subfamily Loimoinae (Monogenea), With A Description Of A New Genus, Harold W. Manter, Waldo L. Schmitt

Harold W. Manter Laboratory of Parasitology: Library Materials

The subfamily Loimoinae was named by Price (1936) for a peculiar monogenetic trematode, Loimos salpinggoides MacCal lum, 1917, from the gills of a dusky shark, Carcharias obscurus (Lesueur), at Woods Hole, Massachusetts, USA. Price (1938) redescribed this trematode, correcting several errors made by MacCallum. Manter (1938) described Tricotyle scoliodoni from a shark, Scoliodon terrae-novae (Richardson), from Beaufort, North Carolina, USA. He noted some similarities between Tricotyle and Loimos. The redescription of Loimos by Price increased these similarities.

A Study Of The Respiratory System Of The Sparrow (Passer Domesticus), Ben Peter Arnowitz

Bachelors’ Theses

The respiratory mechanisms of birds, unlike that of mammals, are definitely adapted to the function of flight. Because of this added adaptation, we should expect, therefore, some morphological and perhaps even embryological, physiological, and histological differences. An example of a morphological difference between birds and mammals is the intricate system of air-sacs that are present in birds. This remarkable feature is probably the reason why birds are able to fly as they do.

In this thesis the writer has used the sparrow (Passer domesticus) for the basis of his experiments. This particular bird was chosen in preference to …
