The finding of the eggs may be facilitated by mixingthe feces with a nine-tenths saturated aqueous solution ofsodium chloride in a test tube and examining microscopicallythe superficial portions of the fluid, where any eggs presentwill accumulate because their specific gravity is less thanthat of the fluid. This procedure was first recommended byBass. In fresh feces, eggs containing several embryoniccells are most common. (See Fig. 141.) Trichinellse (Figs. 142, 143) are obtained

Trichinellse (Figs. 142, 143) are obtained from the freshmuscle by means of teasing. A quick method is to squeezesmall bits of tissue between two slides and examine with alow power. Pieces of muscle nearest the insertion of thetendon are chosen from the diaphragm or from the musclesof the jaws. Encapsulated and calcified trichinellae are clearedup by means of acids. ANIMAL PARASITES, 409 In hardened tissues the trichinellae are best studied inlongitudinal sections of the muscle-fibers. The other round-worms which sometimes occur in the.
