Book Description
Excerpt from The Early Stages of Tabanidae (Horse-Flies) There is, however, another consideration of some importance which has guided me in preparing this review; that is, the desirability of having, generally, all the facts on one subject of research concentrated in one language, preferably English. The diversity of languages is a great hindrance for the progress of science, and from the point of view of methodical unification, specialists in any branch of science should be encouraged to concentrate all the literature on their own subject in the language which they prefer to have used. Having given considerable time to the study of this question, I cannot see any serious objection to the more general adoption of English in science. It is to be hoped that the temporary disadvantages to the non-english-speaking scientists, resulting from its adoption would be made up by the advantages of a great progress in science which would undoubtedly follow. It is for the scientists of English-speaking countries to pave the way, by conquering the field systematically, subject after subject, and to facilitate the production of new work by a complete assimilation of work previously done in foreign languages. I wish to express my indebtedness to the authorities of the American Museum of Natural History and of the Philadelphia Academy of Natural Science for giving me liberal access to their libraries and collections, and to Dr. Theobald Smith, Director of the Department of Animal Pathology under whose guidance this work was rendered possible.

Book Description
Excerpt from Habits and Life Histories of Some Flies of the Family Tabanid This species was reared from the egg to the adult. The fly is one of the earliest of its genus to appear in the spring, adults having been taken at Columbus, Ohio, as early as May 20, and it is common during the first half of June. The eggs are placed in masses on various plants that grow in low, wet ground, but I have not observed them over water. The masses are pure shining black when fully colored, rather small for members of the genus, only slightly convex, and accompanied with an unusual amount of cementing material, which nearly obscures the form and arrangement of the individual eggs. The mass in place suggests somewhat a drop of tar or other black substance fastened to the surface of a leaf of the common cattail reed (typha latifolia), a sedge, or some other plant.
