Extract

1. Careful search has failed to disclose the presence of flame cells in the excretory system of the adult liver fluke.

2. Fat globules are produced in the walls of the excretory system, and are freed into the lumen, and thus to the exterior.

3. These globules do not contain appreciable quantities of cholesterol, cholesterides or lipins, but may contain some unsaturated fatty material.

4. The aqueous medium in which the globules float is either neutral or slightly alkaline.

5. The distribution of reduced ascorbic acid has been investigated by the silver nitrate technique. This indicates that the main concentration occurs in the smaller vessels of the excretory system, and in the submuscular tissues of the body wall.
