This thesis examines the history of Jefferson, Marion County, Texas, and its cycle of prosperity and decline.

The idea of the Texas Revolution as an internal conspiracy cannot be eliminated. This thesis describes the role of a small minority of the wealthier settlers in Texas in precipitating the Texas Revolution for their own economic reasons. This group, made up of many of the leading figures in Texas, were, for the most part, well-to-do farmers, merchants, and professional men.. Most of them were slaveholders, and their prosperity depended upon the continued existence of this institution. In their minds, the entire economic growth and development of Texas rested upon slavery. When the Mexican government began to threaten the economic future of Texas by the passage of prohibitatory laws on slavery and commerce, many of the leaders in Texas began to think of freeing Texas from Mexican control. The threat to their own economic position and prosperity gave birth to the idea of Texas independence.

Many experiments have been performed with the Warburg apparatus, or variations of this manometric technique, since Warburg's experiments (52, 53) where the effects of cyanides upon dark reactions and of urethanes upon light reactions of photosynthesis were demonstrated. The same basic techniques were utilized in this research in attempting to determine the effects of some coordination complexes upon the apparent photosynthetic rate of Chlorella pyrenoidosa. A second goal of the present paper was to investigate the potential of the Warburg apparatus as a tool for screening algicidal compounds.
