an English medical writer. While at Salisbury he published in 1742 ‘An Inquiry into the Nature, Cause, and Cure of the Epidemic Fever of that and the two preceding years.’ In this treatise he objected to bleeding as a part of the treatment, and was consequently attacked by another Salisbury physician, a Mr. Hele, in a local newspaper. Barker replied in a pamphlet entitled ‘A Defence of a late Treatise &c.,’ 1743. He also published in 1748 in an octavo volume ‘An Essay on the Agreement between Ancient and Modern Physicians, or a Comparison between the Practice of Hippocrates, Galen, Sydenham, and Boerhaave.’
