    i the course of the recovery, the same part becomes yel- lw; probably in consequence of the greater part of it be- ig removed by absorption or otherwise; for, Sir Isaac New- tn observes, that blood, reduced to thin lamina, assumes a jllow colour. Jt is observed, by Dr. Rush, that in some sbjects, the yellow colour did not come on till a few mi- ntes after death; wrhich seems favourable to the opinion (its arising from something in the mass of blood, and not bm bile. And as the yellow colour first shows itself about ie neck, and sometimes in broad spots on the trunk o[ the dy, it is hardly conceivable that such partial affections be owing to an effusion of bile, which would necessa- act equally and generally*. Again, Indeed the yel- ljvness of the skin, like the black vomiting, is not an in- iable symptom of this fever, [yellow fever.] Those who a^ so fortunate as to recover, seldom have it, and many dj without its appearance. Besides, the yellowness alone leas to nothing certain. It may arise from an inoffensive suision of bile, as well as from a gangrenous state of the bllcdt. The yellowness does not appear on the skin and ey: until the second stage, (or that of metaptosis,) accord- in, to MoselyJ—according to Hosack, Towne, and Hil- la^.not until the third day§. And the following fact, stated ontle authority of Sir Gilbert Blane, puts this matter to rest, anmroves that this yellowness may be owing to an external caul. Some instances occurred in which this symptom (yeftwness) was contagious, without being attended with the dier characters which distinguish this disease, [yellow fevei] It was observed, in men belonging to the Royal Oak^vithout any symptom of malignity, though evidently infecous ; and at the hospital, it was known to spread frommen affected with the fever, in its worst form, to * Siflilbert Blane on the Diseases of Seamen—London, 1803, p. 411—12, t Meley on Tropical Diseases—London, 1795—p. 413. | lb.. 420. } Hoick's Nosology, second edition, p. 191,—Towne, p. 23, and Hillary, p. 149.
