who merits notice as being the first who performed the flap-operation in amputation.

In the 17th century also lived Frère St Cosme, a French monk, who obtained considerable fame as an operator for lithotomy, for the performance of which he regarded himself as especially chosen by Heaven. In the 18th century lived in England Cheselden and Douglas, two eminent lithotomists; John Hunter, Pott and Ley; in Scotland, Benjamin and John Bell and Monro; and in Ireland, O’Halloran and Deases; whilst in France flourished Petit, celebrated for his treatise on diseases of the bones; from Germany, Rechter and Haller.

In this century (1784) was founded the Royal College of Surgeons in Ireland. In the present century there are few branches of science in which greater progress has been made than that of surgery. From amongst the most eminent of the English surgeons of the present century we may select the following names:—Abernethy, Blizard, Astley Cooper, Brodie, Dalrymple, Guthrie, Aston Key, Liston, Stanley, Travers, Arnott, Bowman, Erichsen, Fergusson, Prescott Hewett, Hilton, Lane, Lawrence, Paget, Spencer Wells, Marshall, Christopher Heath, Durham, Bryant, Nunn, Lee, H. Smith, Mason, and Pollock.

SUSPENDED ANIMATION. See Asphyxia.

SWAL′LOW. Three or four species of hirundo (Linn.) pass under this name. It was once held in great repute in medicine. Even the excrement was included among the simples of the Ph. L. 1618. The swallow is an insectivorous bird, but, like the sparrow and rook, is much persecuted for its good services. It has been calculated that, directly and indirectly, a single swallow is the humble means of lessening the race of one kind of insect alone to the extent of 560,970,489,000,000,000 of its race in one year.

SWEEPING. Before commencing to sweep, the floor should be strewed with a good amount of damp tea-leaves, saved for the purpose; these collect the dust and thereby save the furniture, which as far as practicable should be covered up during the process. Tea-leaves may also be advantageously used upon druggets and short-piled carpets. Light sweeping and soft brooms are desirable if these latter are to be operated upon. Many a carpet is prematurely worn out by over-violent sweeping.

In sweeping thick-piled carpets, such as Axminster and Turkey carpets, the servant should always be instructed to brush the way of the pile; by following this advice the carpets may be kept clean for years; but if the broom is used in a contrary direction, all the dust will be forced into the carpet, and soon spoil it.

SWEET BALLS. Prep. Take of Florentine orris root, 3 oz.; cassia, 1 oz.; cloves, rhodium wood, and lavender flowers, of each 12 oz.; ambergris and musk, of each 6 gr.; oil of verbena, 10 or 12 drops; beat them to a paste, form this into balls with mucilage of gum

tragacanth made with rose water, pierce them, whilst soft, with a needle, and, when they are quite dry and hard, polish them. Worn in the pocket as a perfume. Some persons varnish them, but that keeps in the smell.

SWEET BAY. Syn. Laurel; Laurus nobilis (Linn.), L. The fruit (LAURI BACCÆ; LAURUS—Ph. L.), as well as the leaves (LAURI FOLIA), are reputed aromatic, stimulant, and narcotic. They were formerly very popular in coughs, colic, hysteria, suppressions, &c.; and externally, in sprains, bruises, &c.
