with the locality where that occurs, becomes proporti= =onately thickened and indurated, and it will be necessary in order to separate the true pleura from the morbid structure by which it is enveloped, to dissect away the false membrane (and it will be found quite possible to do this): the pleura can then be discovered entirely distinct and independent of the false mem= =brane; and such blood-vessels as still remain within it will be found to be in connection with the pul= =monary and not with the Bronchial systems. Induration of Pulmonary tissue When it occurs that such false membranes are formed, not only is the sub-jacent cellular tissue thickened and hypertrophied, but the parenchymatic structure itself also (forming the leaflets or pulmonary tissue) in the immediate locality is at the same time toughened and made to resemble parchment. This toughened and hypertrophied structure which occupies the situation which in a state of health belongs to the air-cells, can be injected with consi= =derable minuteness by the Bronchial artery, but it will be found that this altered structure will admit of only a very sparing and insufficient quantity of the fluid sent into the Pulmonary artery, passing into its capillaries, although every other part of the lungs
