                                specimen. It is always preferable to inject the 
Bronchial vessels exclusively in one preparation 
and the Pulmonary vessels in another - When this 
is done it will be observed that particular vessels 
which are never injected from the pulmonary system, 
are well distended by injecting the Bronchial ar=
=teries, and that a perfectly distinct set of vessels, 
belonging exclusively to the Bronchial system, and 
having very marked peculiarities of their own, 
are brought to light by such an injection, and 
it is further seen that such an injection, sent into 
the Bronchial arteries, will never in any case, 
except as the result of rupture, enter those vessels 
which are peculiar to the pulmonary system. 
When on the other hand the pulmonary vessels 
are alone injected, it is seen that the injection is 
confined to a particular distribution, which is per=
=fectly definite and never encroaches upon that 
particular arrangement, which is allotted to the 
Bronchial arteries. If however it be attempted 
to inject the Bronchial arteries with one colour 
and the pulmonary vessels with another in the same 
specimen, it will be found that the Pulmonary 
vessels so greatly preponderate in dimensions and numbers over
