Item A study of the anatomy and histology of the digestive tract of tabanus atratus Fabricus(Montana State University - Bozeman, College of Agriculture, 1917) Wells, Roscoe W.In spite of the importance of many species of Tabanidae as parasites of horses and cattle, as pests of man and as possible agents in the transmission of certain diseases, very little has been published dealing with their internal anatomy. This lack of literature is especially noticeable concerning American species. The most valuable work on the subject to date is that of Patton and Craig (Text book of Medical Entomology), which concerns species native to India. The present paper is a result of a study of the anatomy and histology of the digestive tract of Tabanus atratus Fabricius and is submitted as a part of the requirements for the Degree of Master of Science.Item A study of the correlation of the characters of barley(Montana State University - Bozeman, College of Agriculture, 1913) Hodgskiss, John EdwardThis study is made for the purpose of finding whether correlations are present in various characters of barley and also for the study of correlation in general. Until recently practically nothing has been done along this line, especially with barley. However, we find some attention has been paid to the correlation of nitrogen content, mealiness, color of grain and paleae, length and thickness of internodes, fineness of hull, average weight per kernel, and length of head. Most of this was done before the modern statistical method was introduced.
