are given off, the structure of the Bronchial
tubes splits as it were into two layers: the
thicker, firmer, and most elastic of the two
expands and encloses an ultimate portion
of the lungs (called in this treatise a leaflet),
and becomes continuous with the fibrous tissue,
which encloses the rest of the parenchymetic
structure, dipping down between the different
lobules and leaflets, so as to form the sulci,
by which they are divided - Five or six of
these pedicels are usually given off at the
spot, where the Bronchial tube undergoes
this change, and each of these enters a distinct
leaflet, but each of these leaflets receives nu=

Each pedicel on entering the leaflets, expands
into processes, which extend to the perimeters
of the leaflet and divide its interior into
numerous compartments - These compartments
usually go by the name of 'air-cells.
