In order to guard against the risk of injecting
the Bronchial arteries and capillaries by the same fluid
which is being forced into the pulmonary <s>artery<\s> veins
a strong ligature should be passed around the root
of the aorta, so as to prevent any injection,
which might be forced into the left ventricle through
the mitral valve, from finding its way into the
aorta. These preliminaries having been arranged
it is advantageous in the next place to pump a
quantity of warm water through the pipe inserted
into the pulmonary artery and to continue to do
so until it passes out quite clear through the pipe
inserted into the left auricular appendix - The object
of this is to clear away the blood, which would
otherwise remain in the capillaries of the Pulmonary
vessels, and would prevent the coloured fluid from
duly entering them - This done the suction pipe of
each pump is to be placed in the vessel contain=
=ing the appropriate injection. If the intention
is rather to shew the capillaries in connection with
the pulmonary artery in preference to those <s>in<\s> more im=
=mediately in relation with the pulmonary veins, it
will be desirable to use freshly precipitated chromate
