THE DORSAL VESSEL OF THE IMAGO OF THE BLOW-FLY. The dorsal vessel commences near the posterior border of the fifth abdominal segment, arches forward immediately beneath the integument, and terminates in the aorta at the inferior margin of the mesophragma. It can be most readily seen in situ by making a vertical longitudinal section, a little on one side of the median line, Fig. 86.—a section through the dorsal part of the abdomen of a lilovv-fly, showing the dorsal vessel, a, aorta ; e/i, chyle stomach ; i, intestine ; m, mesophragma ; /, pericardial septum ; xr, scutellum ; v', v', v'', 2nd, 3rd, and 4th ventricular enlargements of the dorsal vessel. The longitudinal fan-like alar muscle is seen covering the two anterior enlargements. through the body of a Blow-fly which has been previously hardened in a i per cent, solution of potassium bichromate, and afterwards in strong alcohol (Fig. 86). The anterior part of the dorsal vessel is then seen between the intestine and the abdominal wall; the posterior part is more difficult to trace, and can only be studied in serial sections and when the whole pericardium and dorsal vessel have been removed from the body of an insect. This can be done by taking away all the structures which lie beneath it, so as to leave the pericardium on the inner surface of the dorsal wall of the abdomen. The posterior 42
