Study of Colorado Protozoa
The following abstract is taken from the introductory paragraph of the thesis. "To the zoologist, the Protozoa which are found in the fresh and marine waters, rivers, lakes, ponds, drinking water, the air we breathe, in fact, nearly every place, afford an intensely interesting and prolific field for special study. They are capable of changing and adapting themselves to nearly every sort of environment and therefore may be expected to occur in nearly every sort of condition. The Protozoa constitute an important group, not only because of the position they occupy in the scale of animal life, but also because of their economic importance both negative and positive. These tiny animals, because of their unicellular nature, lend themselves much more readily to microscopic study than do the higher forms, which fact makes it possible to study some of the phenomena exhibited by the specialized forms by having a knowledge of the characteristics and behavior of these tiny organisms."
