It will be found that nothing can be easier than to trace out the course and Ramifications of the Pulmonary arterys and veins when a pair of lungs, injected in the manner above described, with the arteries of one colour and the veins of another is examined - The mode of distribution of each is marked, decisive and invariable. The Pulmo= =nary artery The Pulmonary artery is seen always accom= =panying the Bronchial tube, dividing as it divides and maintaining an exact correspon= =dence with its subdivisions, down to the point at which the terminal Bronchial tubes give off their pedicels - In some works it is asserted that as they diminish in size the <s>Bronchial<\s> pulmonary arteries become more numerous than the Bronchial tubes; this is not the case: whenever there is a Bronchial tube there is also one corresponding Pulmonary artery and never more than one - Throughout the lung the Pulmonary artery always runs on the upper surface of the Bronchial tube, and
