Where tliis [jrocess is not of long standing, thewalls of the alveoli are thickened owing to the distension of the capil-laries; near these capillaries a number of larger cells are usuallyfound within the air vesicle. Outside this narrow zone the air vesiclesare filled with catarrhal cells, with little or no fibrin between them. 462 THE LUNG These, or their nuclei, are deeply stained, and the mass is not nearlyso transparent as is the exudation in the central zone. Here, too,the capillaries in the walls of the air vesicles are distended. Thecatarrhal change may extend to the periphery of the lobule, but in • •• •;., .0,V .--:.. ?-?•?•!• ;?«?- iJiiJ.
