V. No more than two questions may be asked in one letter, which must be addressed to the Editor of "The Girl's Own Paper," 56, Paternoster Row, London, E.C. VI. No addresses of firms, tradesmen, or any other matter of the nature of an advertisement will be inserted. MEDICAL. EMILY DALTON.--We thank you for your letter, but we must remind you that the preparation that cured you is by no means likely to be of equal value to others. If the remedy that you used is one that is not commonly employed for that purpose, we may be almost certain that it would be totally useless in another case. Most unexpected things do happen in medicine, and it requires a long time to decide whether a drug has any good effect, even though it may have apparently cured one or two persons. You are hardly likely to have discovered any new drug, and most of the medicines used in England, whether in the pharmacopœia or not, have been exhaustively studied. Those drugs which are not official are not given a place in the pharmacopœia, either because they are of insufficient value or because they have not yet been sufficiently studied. The reason why patent medicines and advertised nostrums are not given a place in our official list of drugs is either, as is most commonly the case, they are useless or inferior to preparations already in the pharmacopœia, or because they are simply time-honoured prescriptions which have been stolen and patented for running a company with, and charging thirteenpence halfpenny for what can be got for a penny! You must also remember that using drugs, with the action of which you are not familiar, is indeed dealing with edged tools, which may do great good if properly handled, but which can work disaster if wrongly applied.
