These ramusculi are situated on the external sur= =face of the Bronchial tubes - The plexus lining the mucous membrane is obviously a sort of diverti= =culum from the main current, by which the arte= =rialized blood is returned to the left auricle and is quite distinct and independent of any anastomosis whatever; it forms a much more vascular layer over the mucous membrane than can at all be attributed to to the Bronchial vessels, and it may be fairly a matter of doubt whether, if the whole of the Bronchial arteries were exclusively confined to this plexus and had no other distribution, they would be large enough to supply an equally vas= =cular distribution to it - But it has been con= =clusively shewn that the Bronchial arteries are spread out in a very uniform manner to every part of the lungs; its principal distribution being to the fibrous tissue of the leaflets and of the Bronchial tubes - Setting aside this diverticulum sent to the mu=
