The nostril-like parts are olfactory organs in fish, and are connected to the brain with nerves; Aristotle was looking for a connection by means of blood vessels. Cf. Solmsen, F.

^{page 275 note 1} In Somn. Vig. 2. 456^a1 ff. both movement and the dominant sense faculty are in question.

^{page 276 note 1} 10. 703^a9–28. In Somn. Vig. 2, there is something of a contrast between ‘holding the external breath’ and ‘holding the connate ’ to make strength for movement. The distinction between ‘increasing one’s strength’ and ‘using a general instrument of movement’ seems blurred in the PA passage.
