if that were true it would result that no dis=

pulmonary tissue and what Bronchial tube.
Nothing could possibly be more incorrect -
A late author has endeavoured to prove that
each ultimate Bronchial tube terminates in
a kind of trefoil and that an arrangement to
which he gives the name 'alveoli' is connected
with them. This is entirely a mistake as nothing
of the kind exists - These errors arise from
the attempt to make out the structure of the lungs
by examining specimens which have been inflated and dried - When the lung is thoroughly
moist, it can be fully distended by forcing air
into the tubes, and the air will have <s>no<\s> but little tendency
to escape from its meshes so long as that mois=

the lung<s>s<\s> becomes in the slightest degree dryer
the air penetrates through the tissue in every
direction and the character of the spaces where
