to give additional scope and elasticity, and to
avoid the risk of the pressure becoming too great<s>,<\s>
by being exclusively directed onto the Bronchial
arteries); there would be considerable danger of
causing the trunks of the Bronchial arteries to burst
before their capillaries were filled unless these pre=
=cautions were taken - Ligatures must also be
put on the left carotid and subclavian arteries
and the cut edges of the Pleural and cellular tissue
of the posterior mediastinum should be gathered into
bundles and enclosed by ligatures. Ligatures
should be carefully applied to the four pulmonary
veins externally to the pericardium and care must
be observed not to include either the Bronchial arte=
=ries or veins in these - The object of these ligatures is to prevent
any injection which might be forced through the
mitral valve into the left auricle from finding
its way into these veins nd thence into the lungs
and causing the vessels belonging to the Pulmonary
system to become injected -
It is necessary that freshly precipitated chromate
of Lead should be used for the purpose of injecting
the Bronchial arteries, because the capillaries
