The brain and suboesophageal ganglion

1. Remove the glands.

The cut end of the oesophagus will be seen projecting from the space between the brain and the suboesophageal ganglion.

2. If the corpora allata are not visible, pull the oesophagus out a little way with forceps, when they should come into view.

3. Trace:

   3.1. the principal nerves (Fig. 24);

   3.2. the ducts of the glands (Fig. 15).
