Mercury is used in syphilis, tonsillitis and other glandular affections, gastritis, dysentery, gastric ulcer, early cirrliosis of the liver, typlioid fever, diphtlieria, Asiatic cholera, pneumonia, "astro-enleric disturbances, conjunctivitis, en- larged thyroid, and enlarged spleen. Bicldoride of mercury is very largely used as an antiseptic. It is irritant and corrosive, and in toxic doses causes severe gastro-intestinal irri- tation, nausea, vomiting, suppression of urine, blood.v diarrhoea, convulsions, and collapse. It is, however, a very safe and valuable internal remedy in proper dosage. It occurs in heavy, colorless crystals, with sharp metallic taste and acid reaction. It is soluble in 2 parts of boiling water, 3 of alcohol, and 10 of water. Its symbol is HgCL. It is used locally as a parasiticide in a solution of I part in 250 parts of water, and as a general surgical antiseptic in a solu- tion of I part to 1000 of water, or 1 to 2000, sometimes 1 part to 5000 of water. In these dilutions it is an efficient antiseptic for cleansing wounds, moistening gauze dressings, injecting into cavities, etc. See the articles Antidote and Toxicology.

They are of two classes, choir sisters and la.v sisters, the choir sisters being occupied with the visitation of the sick and prisoners, the care of poor and virtuous girls, and other charities ; the la.v sisters being employed in the domestic occupations of the con- vent. Each comnuniitv is independent of the rest of the Order, being subject onl.y to the bish- ops. The origin of the Order was due to Miss Catharine McAuley, of Dublin, who. born of Roman Catholic parents and left an orphan, hav- ing been educated a Protestant, joined the Ro- man Catholic Church and devoted her life and ample fortune to the service of the poor. The Order has been introduced into nurny parts of Ireland, England, Scotland, and America. After a preliminary preparation of six months, candi- dates assume the white veil and become novices. The novitiate lasts two ,vears. Their vows bind them to poverty, celibacy, obedience, and the care of the sick and poor. In the United States their first, now the luother, house was opened in Pittsburg, Pa., in 1843, and they are now very widespread and have sixty-five convents.

He was born in Hampshire, February 12. 1S28. and received part of his earl.v education in Germany — a land whose influence, especially through its poetry and music, is perceptible in his writings. On returning to England he studied law for a while, but soon abandoned it, as his literary genius began to make itself felt.
