Note 52 — OF THE PERIPNEUMONY.

Some late Authors seem to look upon the Pleurisy and Peripneumony as the same Disorder: However, though it be true, that when the Pleura is inflamed, the Surface of the contiguous Lungs is generally in the same State; and that, when the Lungs are inflamed, the Pleura is often affected; yet as I have frequently seen the true Peripneumony without that sharp Pain of the Side which characterizes the Pleurisy; and upon opening the Bodies of People who have died of the Peripneumony, have found the Lungs violently inflamed and livid, and so filled with Blood as to sink in Water, without the Pleura being much diseased; and upon opening the Thorax of others who died of the Pleurisy, have found the intercostal Muscles and Pleura violently inflamed with livid Spots, and only a small Portion of the Surface of the contiguous Lungs affected; I cannot help still looking upon them as distinct Disorders; though they require nearly the same Treatment, and are often complicated together.
