Dr. Saunders fufpects the acute hepatitis to exift in the in- 

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

 of the vena portartim. Tiea.ti.fe on the Liver. Robinfofts*

13. Scrofula fuppurans . Suppurating fcrofula. The indolent 

 •tumors of" the lymphatic glands are liable, after a long time, to 

 regain their fenfibility *, and then, owing to their former torpor, 

 an increafed action of the veiTds, beyond what is natural, with 

 inflammation, is the confequence of their new life, and fuppura- 

 tion fuceeeds. This cure of fcrofula generally happens about 

 puberty, when a new energy pervades the whole fyftem, and un^ 

 folds the glands and organs of reproduction. 



M. M. SeeClafsI. 2. 3. 21. Where fcrofulous ulcers about 

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

 land, that an empyrichad had fome fuccefs by inflaming them by 

 anapplication of wood forrei, oxalis aceto fella, the leaves of which 

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

 three days, and then fome more lenient application is ufed. 



A poor boy, about twelve years old, had a large fcrofulous ul- 

 cer on one fide of the cheft 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 ihew me that both the ulcers are quite healed. The con- 

 ftant application of linen rags, moiflened with a folution of an 

 ounce of fugar of lead in a pint of water, I think I have feen 

 equally efficacious. 



Small dofes internally of a folution of arfenic have been faid 

 to contribute to cure thefe ulcers. I mould recommend from 

 one drop to five of a faturated decoction of arfenic, 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 per- 

 fons, diminifhing the quantity if it affects the bowels. Tine?- 

 ture of Digitalis is recommended in Clafs I. 2. 3. 21, 



14. Scorbutus fuppurans* In the fea-fcurvy there exiits an 

 inactivity of venous abforption, whence vibices and petechia, 

 and fometimes ulcers. As the column of blood prefiing on the 

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

 erect, oppofes the afcent of the blood in them, they are more 

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

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

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

 caufe cf ulcers on the extremities j as happens to many of the
