Correspondence. Advice by letter from time to time will be given to any patient whilst continuing Mr. Congreve’s Treatment, provided that the 22s. or 11s. bottles of Elixir are _obtained direct from_ [the address given by the vendor in his advertisements] during the period of correspondence. The directions were: _For adults._—Take a teaspoonful, alone or mixed with honey or lump sugar, three or four times a day, as the urgency of the case requires. Children from 8 to 15 years may take two-thirds of a teaspoonful; from 5 to 8 years, half a teaspoonful; from 2 to 5 years, twenty drops; at six months, ten drops; younger infants from four to six drops. The “elixir” was a bright red liquid; analysis showed it to contain 28·5 per cent. by volume of alcohol, and 2·6 per cent. of total solids; the latter consisted of resinous constituents (about 0·5 per cent.), sugar (about 1 per cent.), a little tannin, colouring matter (apparently cochineal), and extractive. Alkaloid was present only to the extent of a trace, under 0·001 per cent.; the extractive showed no characters by which its source could be determined; the resinous material was of an aromatic nature similar to the resins of benzoin, storax, tolu, or balsam of Peru, and appeared to be derived from a mixture of two or more of these. No other active ingredients were found to be present. THE BROMPTON CONSUMPTION AND COUGH SPECIFIC. The “Sole proprietor” gives an address in a part of London remote from Brompton, but it is perhaps hoped that the name may suggest some connection with the well-known Brompton Consumption Hospital. The price charged is 1s. 1½d., 2s. 9d., 4s. 6d., and 11s. per bottle; the 2s. 9d. bottle contained 3⅔ fluid ounces. The origin of the preparation is thus described: This Specific is prepared from the Prescription of an eminent Physician, who practised nearly forty years in Madeira, he was celebrated for his success in the treatment of Consumption and diseases of the Chest. Upon a visit to this country some years since, he gave the Prescription to a late Physician, who tried it upon five hundred out-patients; its effect was wonderful; it acted like magic upon their Coughs, and prevented that great waste of strength and flesh peculiar to this disease. It will save the lives of thousands and prevent Consumption, by administering it upon the first symptoms of Cough, which will be immediately cured by a few doses. In a circular enclosed with the bottle it was stated:
