CLASS II. 1. 4. 13. OF SENSATION. 221 



Dr. Saunders suspects the acute hepatitis to exist in the in- 

 flammation of the hepatic artery, and the chronical one in that 

 of the vena portarum. Treatise on the Liver. Robinsons.

13. Scrofula suppurans. Suppurating scrofula. The indolent 

 tumours of the lymphatic glands are liable, after a long time, to 

 regain their sensibility; and then, owing to their former torpor, 

 an increased action of the vessels, beyond what is natural, with 

 inflammation, is the consequence of their new life, and suppura- 

 tion succeeds. This cure of scrofula generally happens about 

 puberty, when a new energy pervades the whole system, and un- 

 folds the glands and organs of reproduction. 



M. M. See Class 1. 2. 3.21. Where scrofulous ulcers about 

 the neck are difficult to heal, Dr. Beddoes was informed, in Ire- 

 land, that an empyric had had some success by inflaming them by 

 an application of wood sorrel, oxalis aceto sella,the leaves of which 

 are bruised in a mortar, and applied on the ulcers for two or 

 three days, and then some more lenient application is used. 



A poor boy, about twelve* years old, had a large scrofulous 

 ulcer on one side of the chest beneath the clavicle, and another 

 under his jaw; he was directed, about three weeks ago, to pro- 

 cure a pound of dry oak-bark from the tanners, and to reduce it 

 to fine powder, and to add to it one ounce of white lead in fine 

 powder, and to cover the ulcers daily with it, keeping it on by 

 brown paper and a bandage. He came to me a few minutes ago, 

 to shew me that both the ulcers are quite healed. The constant 

 application of linen rags, moistened with a solution of an ounce 

 of sugar of lead in a pint of water, I think I have seen equally 

 efficacious. 



Small doses internally of a solution of arsenic have been said 

 to contribute to cure these ulcers. I should recommend from one 

 drop to five of a saturated decoction of arsenic, as directed in 

 Mat. Med. Art. IV. 2. 6. 8. for children, twice or thrice a day, 

 according to their age, and from five to ten to grown persons, 

 diminishing the quantity if it affects the bowels. Tincture of 

 digitalis is recommended in Class I. 2. 3. 21. 



14. Scorbutus suppurans. In the sea-scurvy there exists an 

 inactivity of venous absorption, whence vibices and petechiae, 

 and sometimes ulcers. As the column of blood pressing on the 

 origins of the veins of the lower extremities, when the body is 

 erect, opposes the ascent of the blood in them, they are more 

 frequently liable to become enlarged, and to produce varixes, or 

 vibices, or, lastly, ulcers about the legs, than on the upper parts 

 of the body. The exposure to cold is believed to be another 

 cause of ulcers on the extremities; as happens to many of the
