SE′TON. Syn. Setaceum. An artificial ulcer, made by passing a portion of silk or thread under the skin by means of a seton needle, a part of which is drawn through daily, and thus keeps up a constant irritation. Occasionally the thread is anointed with some irritating substance for the purpose of increasing the discharge.
SEVEN SEALS, or Golden Wonder—Dr Radcliffe’s Great Remedy. According to the prospectus, this remedy is good for cholera morbus, dysentery, diarrhœa, burns, sprains, rheumatism, warts and corns, and all diseases. In a quadrangular bottle we find about 95 grammes of a brownish-orange clear fluid,
which is a spirituous tincture of cayenne pepper mixed with ether, chloroform, American oil of peppermint, and a little camphor. The proportion of these ingredients is, approximately, 4 grammes ether, 6 grammes chloroform, 4 gramme camphor or camphoraceous oil, 2 grammes oil of peppermint, 35 grammes tincture of capsicum. 50 grammes spirit of wine (90 per cent.) (Hager.)

2. As MAGNETIC ADEPS. Used to make mercurial ointment. Triturated with 8, 12, or 16 times its weight of quicksilver, the globules are completely extinguished in from 10 to 15 minutes.
SEWAGE, Removal and Disposal of. The waste and putrescible refuse discharged from dwelling-houses by house-pipes and drains into sewers may be said, in general terms, to consist, besides human fæces and urine,[150] of the dirty water and soapsuds arising from washing our bodies, our houses, and linen, more or less foul, as well as the water which, having been used for cooking operations, necessarily contains variable quantities of mineral and vegetable matter.
[150] In the drainage of some towns the fæces are not allowed to enter the sewers. This, however, is the exception.
The above statement will have prepared us not only for the complex nature of sewage water as shown in the following tables, but also for the variability in the amount of its constituents, this latter condition depending upon locality, and, as experiment shows, the hour of the day at which the sewage was collected.
