The Morphology Of The Seminal Vesicles, Accessory Glands, And The Ejaculatory Canal Of Melanoplus Differentialis (Thomas) And An External Morphological And A Histological Study Of The Seminal Vesicles, Accessory Glands, And Ejaculatory Canal Of This Grasshopper, Wilbur T. Reierson
Electronic Theses and Dissertations
The purpose of this thesis is to record the results of an investigation, by the writer, upon the reproductive system of Melanoplus differentialis (Thomas) with special emphasis placed upon the external morphology and the histological study of the seminal vesicles, accessory glands, and the ejaculatory duct; and also to record conclusions as to the probable function of these organs.

Some Effects Of A Constant Temperature And Different Relative Humidities Upon Egg Laying Of Melanoplus Bivittatus Scudder., Millard Jewell Hatten
Electronic Theses and Dissertations
Of the various species of grasshoppers occurring in rather extensive numbers year after year in the northwestern plains states, Melanoplus bivittatus is one of the most prevalent and destructive. It was thought that a study of the influence of different temperatures and relative humidities upon the reproductive potential of this species might reveal some information and that this information might be of some value in an attempt to forecast the abundance of this grasshopper in years following others in which the factors of temperature and relative humidity were known.
Farm Mortgage Experience Of Life Insurance Companies Lending In South Dakota, Harry Allan Steele
Farm Mortgage Experience Of Life Insurance Companies Lending In South Dakota, Harry Allan Steele
Electronic Theses and Dissertations
Life insurance funds play an important part in supplying farm mortgage credit. This source of credit has increased rapidly during the last twenty years and is now one of the principal sources of farm mortgage loans in the United States. Because of the nature of the institution of life insurance, its investments should be conservative. It is with this view in mind that the state insurance laws are designed to regulate the investments of the life insurance companies. Investments of the well established life insurance companies have generally been made on a conservative basis.
Anatomical Study Of Water Shoots And Ordinary Twigs, Dorothea I. Bingham
Anatomical Study Of Water Shoots And Ordinary Twigs, Dorothea I. Bingham
Electronic Theses and Dissertations
Water shoots or long shoots are those which appear low on the trunks of trees, or about stumps of trees recently cut down. The ordinary twigs are those found at the ends of branches. Interest in the cooperative study of water shoots and ordinary shoots on trees was aroused by the very marked differences, even in a single years growth, in length and the diameter of two types. The former is greater in diameter , much longer, and with more nodes, longer internodes and longer leaves than the twigs which grew ordinarily at the ends of branches. The object of …

Certain Cultural Characteristics Of Digitalis Pupurea, (Linne) With A Proposed Chemical Assay, Clark W, Eidsmoe
Electronic Theses and Dissertations
Since its introduction into modern medicine digitalis has occupied a very important position in our material medica. Its widespread use as a remedy in conditions of failing heart, and its effectiveness as a diuretic in certain dropsical conditions have gained for it a reputation which is equaled by few other drugs. The opinion of pharmacologiate and physicians as to its mode of action and its field of clinical usefulness has been revised a number of times, and there is much diversity of teaching as to its use in special ailments. Among some workers there is a tendency to restrict its …

Studies In The Life History Of The Croton Bug, Blatella Germanica (Linnaeus), Laurence Adams Carruth
Electronic Theses and Dissertations
The Croton bug, or German Roach as it is commonly called, has been widely known for centuries. In the past, a considerable amount of work was done in attempting to find methods of controlling this insect, but relatively little attention was given to a study of its morphology, time of development, or to the finer details of the life history. this lack of information is probably due, in part to the fact that there are several similar common species of roaches and also because the Croton bug has probably received less attention than the other roaches, at least from a …
