Most of Domenico Scarlatti's harmonic progressions are quite orthodox when considered abstractly or free of their positioning in the score. The harmonic movement is given interest by subtle alterations in time; for example, (1) simultaneous upper and lower voices of different lengths, when repeated several times, change their relationship with each other; (2) one voice may be simply delayed so that it lags behind the other voice, thus combining to produce irregular harmonic sound on many succeeding beats; (3) the combination of two or more chords appearing on one beat is similar to number (2) but does not necessarily occur more than once.

Born April 2, 1873, on the estate of Oneg in the province of Novgorod, Russia, Sergei Vassilyvitch Rachmaninoff was the fifth of the six children of Vassili and Lyoubov Boutakova Rachmaninoff. Rachmaninoff's aristocratic descent was traced to the Hospodars Dragosh, rulers of the realm of Molday from the fourteenth to the sixteenth century. One of the daughters from this family had married a son of the Grand Duke Ivan III of Moscow. The son's nephew was named Rachmanin, and from this source the family name originated.1 Rachmaninoff's mother was the daughter of a general, head of Araktcheyev Military College in Novgorod and the owner of a number of estates in the district. It was with a dowry of five of these estates that Lyoubov Boutakova married Vassili Rachmaninoff, and on one of these estates, Oneg, the couple settled down to married life.

"The purpose of this thesis is to examine the age structure of the population of Texas as it existed in 1960, and insofar as possible to trace important changes and trends in the older group from 1900 to 1960. The qualification derives from the fact that at this time not all of the data from the 1960 census are available, and hence many trends can be described only through 1950. Where appropriate, the structure and trends characteristic of the total population will be described, usually for comparative purposes."-- leaf 1.

Undoubtedly, Dostoyevsky's influence upon the novel is great, but, even yet, few concrete studies have been made and no full-length study has been published. It is hoped that this account of Dostoyevsky's reputation in America during the 1920's will be of assistance in the greater task of tracing Dostoyevsky's influence.

In this study the effects of repeated antigen injections on total complement (C') and C'4 of guinea pig serum were investigated to determine if constant antigenic stimulation would show changes in the C' and C'4 titers. Attempts were also made to correlate any changes with variations in antibody titers during the repeated antigen injections.

"The purpose of this study was to collect and analyze locational data on all branch maufacturing plants established in Dallas County in 1954, 1955, and 1956; these data were acquired through personal interviews in 1957. For comparative purposes the same data on branch plants established in 1959 were obtained in 1960. The following elements of the locational process were determined and analyzed: 1. Origin and character of the new plants; specifically location of home office, types of products, size and location of the plant in Dallas. 2.locational process, including company personnel assigned the task of locating a suitable site and local agencies assisting in the locational process. 3. reasons for establishing the branch plant 4. factors that influenced management to locate the plant inDallas in preference to any other locations."-- leaf 4.

It was the purpose of the present investigation to determine if sensitivity to other antibiotics can likewise be affected by subjecting S. aureus to heparin contact. It is of special interest in this problem to determine whether heparin in some manner affects the combining process of penicillin with the cells of several strains of S. aureus.

The history of the Osages from 1808 to 1839 may be conveniently divided into three major sections, each separated by a cession treaty. The first begins with the cession treaty of 1808 and terminates with the cession of 1818. It covers the Osages' relations with the whites and the eastern tribes during that decade. The second section begins with the 1818 session treaty and ends with the land cession of 1825. It likewise covers the tribe's relations with the eastern tribes and the whites. The concluding division covers the period from the Osages' last major cession treaty to their removal to Kansas in 1839, and includes their relations with the eastern tribes, the western tribes, and the whites. These three sections combined cover the most turbulent period in Osage history, a period in which the United States Government and the powerful eastern tribes took the extensive Osage lands by right of conquest.

The purpose of this paper is to present a study of partly ordered sets. It includes a rigorous development of relations based on the notion of a relation as a set, lattices, and theorems concerning the lattice of subgroups of a group.

This paper investigates the Runge-Kutta method of numerically integrating ordinary differential equations. An existence theorem is given insuring a solution to the differential equation, then the theorem is modified to yield an analytic solution. The derivation of the method itself is followed by an analysis of the inherent error.

It is the purpose of this study to utilize three psychometric measures in order to quantitatively assess the group of subjects on the basis of the trait heterosexuality, as measured by the Edwards Personal Preference Schedule, and in turn make predictions on the basis of these data as to choices made on the Bonney-Fessenden Sociograph.

This paper will investigate the geometry that results when Euclid's fifth postulate is replaced by the Lobachevskian assumption. The investigations will be limited to the plane.

This thesis describes an attempt to increase the life span of mice after injection of a leukemic tumor. Fatty acids were used as a protecting agent against the leukemic tumor.

This study is concerned with the determination of the relationship that exists between levels of emotional stability and academic accomplishment among students of Business Administration at North Texas State College. It is the hypothesis of this study that a positive relationship exists between levels of emotional stability and academic achievement among students of Business Administration at North Texas State College and that the degree of this relationship can be determined.

This thesis presents a series of theorems along with proofs to establish a theory of congruences.

The purpose of this thesis is to indicate the use of the mask by Eugene O'Neill. It is probably possible to say that the mask has been used or implied in all of O'Neill's works, but this thesis will be confined to discussion of the works in which the mask or the implication of the mask is specifically evident.
