Give the body a thorough arterial and cavity injection, paying especial attention to the pleural sacs, which should be injected independently from the first intercostal space on each side or from the apex of the cavity. Drain blood and disinfect the contents of the blood bottle before disposing of same. For transportation, govern yourself according to the provisions of the transportation laws. (B) _Broncho-Pneumonia_—_Synonyms._—Capillary Bronchitis; Lobular Pneumonia; Catarrhal Pneumonia. _Definition._—An inflammation of the terminal bronchi, air vesicles, and interstitial tissue of a few or many of the lobules. _Pathology._—The interstitial tissue between the air cells and the capillaries are greatly weakened. In most cases the lung will float when placed in water, though the small mahogany-colored nodules found distributed throughout the lung when excised sink in water. _Treatment._—The nature of the disease is such that preservation is comparatively simple, the disease affecting the extremities of the respiratory system. Arterial injection together with special attention to the pleural sacs will suffice for the cases. For transportation, govern yourself according to the provisions of the transportation rules. (C) _Chronic Interstitial Pneumonia._—_Synonyms._—Cirrhosis of the lungs; Fibroid Pneumonia. _Definition._—A chronic inflammation of the lungs, in which the normal air cells are replaced by fibrous or connective tissue, followed by induration and atrophy of the lung. _Pathology._—The disease is nearly always confined to one lung, though, in very rare cases, both lungs may be involved, while localized areas are the rule. The affected lung becomes atrophied and in extreme cases, may be no larger than the closed hand. As a result of the shrinkage of the lung tissue, the heart undergoes hypertrophy. When tuberculosis exists, cavities of varying size and number are found, and the interstitial tissue between the capillaries and the air cells is very much weakened. _Treatment._—Should this disease be followed by a rupture of the capillaries during the injection, thereby causing a hemorrhage from the oral and nasal openings, treat it as you would a case of pulmonary hemorrhage. Otherwise give the body a thorough arterial and cavity injection with special attention to the pleural sacs. For transportation, govern yourself according to the provisions of the transportation laws. =Hydrothorax.=—_Synonyms._—Thoracic dropsy; Dropsy of the chest; Dropsy of the pleura. _Definition._—A collection of serous fluid within the pleural cavity without inflammation. _Pathology._—Hydrothorax, unless due to cardiac affections, is usually bilateral. The quantity of fluid varies, and is generally greater on one side than on the other. The fluid is free, and of a low specific gravity, alkaline in character, clear, and of an amber color.
