It consists of a median dorsal and two lateral lobes. Sections show that the omentum is much folded and convoluted, that it occupies the greater part of the body-cavity, and has large blood sinuses between its folds. The cells of the fat body (Fig. ig,/ 6) measure about o'i5 mm. in diameter; they consist of a reticular protoplasm, in the meshes of which granules and globules of fat are imbedded. These are so numerous that they conceal the nucleus. Sections show that the cells are bounded by a thin cuticular membrane. These cells have large vesicular nuclei, which undergo very remarkable changes during the development of the Fig. 17.—Blood corpuscles {leucocytes'] of the adult larva : /, living corpuscles, showing the amosboid condition, in d the nucleus is also amroboid ; .?, the same, treated with magenta, showin;,' the various appearandes produced by the action of the ; 3, a living cell in several stages of direct division, all drawn with ,'.t oil immersion lens. (For details see ' Histology of Tissues.') The fat body, although adherent in places to the larger tracheal vessels, has no tracheal capillaries developed on its surface. When removed from the larva and exposed to the air, it rapidly assumes an inky hue, probably the result of The contents of the cells are not easily acted upon by osmic acid, unless the outer wall of the cell is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Lowne, Benjamin Thompson, 1839-.
