ON Aug. 25th at Ilkeston, a grocer was summoned under the Food and Drugs Act on two charges for selling baking powder containing injurious ingredients. From the evidence of Mr. Hehner, the powder in question contained 35’5 per cent. of alum. The alum was used instead of tartaric acid to expel the carbonic acid from bicarbonate of soda. Scientific witnesses, both expert analysts and medical men, were not agreed as to whether the powder would prove injurious when employed to "raise " bread. It was urged for the defence that the chemical process which followed on mixing the powder with the dough rendered it en- tirely harmless. In the end the summons was dis- missed, the magistrates holding that baking powder was not a food and that the powder in question was not sold to the prejudice of the purchaser. This decision is to be regretted. Practically it sanctions the use of alum in a powder which is only used for one purpose-that is, to give porosity and lightness to bread. Bearing this in mind, and not supposing for a moment that baking powder is per sea food, it is a moot point whether the powder in question could not be regarded as being sold to the prejudice of the pur- I chaser. It consisted of alum and bicarbonate of soda. These substances when moistened interact, carbonic acid gas escapes and there remains a residuum of sodium sulphate and alumina. Apart from the fact that there is formed by this double decomposition a salt of strong purging qualities—Viz., Glauber’s salt-it is important to consider what is likely to be the action of the newly formed alumina. It is well known that alumina when precipitated in the presence of certain soluble matters will render them insoluble. This is especially the case with soluble nitrogenous matters. In the chemical treatment of sewage, for example, a large proportion of the- soluble nitrogenous matter is removed by adding to the sewage a mixture of sulphate of alumina and an alkali (generally lime). Alumina as a gelatinous precipitate is thus produced, which then, combining with the organic matter in solution as well as that in suspension,, subsides as a "sludge " in the precipitating tanks. The same method is adopted for fixing otherwise soluble colours or dyes, the alumina compound formed giving rise to the so-called ’’ lakes.’’ Further than this, alumina combines with soluble phosphates to form insoluble phosphate of aluminium. Surely, in the light of these facts, it is seriously to the prejudice of a purchaser if, when he buys a baking- powder, he receives one which is calculated to reduce very materially by reason of the nature of its ingredients the food value of his " stafE of life " by rendering both the nutritious and the bone-forming constituents in it insoluble and indigestible. If baking powders must be used, alum should not enter into their composition, especially as there are other comparatively inert and equally effective agents procurable. When a baker uses alum in his bread or flour, proceedings are successfully taken against him under the- Food and Drugs Act, and it is reasonable to expect that the same Act should protect the purchaser against alum intro- duced into his bread in any other form, not excepting that of a baking powder. - PUBLIC HEALTH IN SWITZERLAND.

TEA AND TOBACCO IN WORKHOUSES.

THERE is nothing more gratifying to human nature than tohave liberty in the use of a valued luxury without either adread of after consequences or a conscientious prick at hearton the ground of self-indulgence. Happily, we are not with-out luxuries which can be thus enjoyed, the observance ofmoderation being always understood. Among them we maynumber the cup that cheers but not inebriates, and also thatmuch valued solace of tired leisure-tobacco. So familiarto our minds do both appear that many of us would includethem rather among the necessaries than the amenities

of life. Guided no doubt by such considerations as

PUBLIC HEALTH IN SWITZERLAND.

THE "playground of Europe," writes a holiday contributor, has lately become its sanitary asylum since the out-break of cholera on the North Sea and Gallo-Batavian coasts.has sent the moneyed classes of those regions to the Bernese-Oberland. As I write, however, under date the 5th inst., asensible diminution in this invasion of the panic-stricken has,been registered in Switzerland-a diminution largely due tothe announcement that in one of the most frequented hotelsin Zurich a case of cholera had occurred. But an official

inspection of the hotel referred to has dissipated this report,reducing it to the prosaic truth that fumigation, as a dis-infecting precaution, had been practised on sundry Germans.hailing from Hamburg. No case of death from cholera, nDcase even of illness from that cause, has been officiallyrecorded in the Confederation. Meanwhile prompt effort has.not been wanting on the part of the Swiss authorities tominimise the chance of the introduction of cholera.L’itat général of the public health has just (5th inst.)been announced by the Bureau Sanitaire Fédéral as ’excel-

lent,’ but, all the same, the measures taken by the Bureaufor the safeguard of the sanitary position are exhaustive andvigilant. M. Dreyfus, Chef du Bureau d’Emigration, is nowin Bale, armed with full powers to send back across the-

frontier the emigrant trains arriving by the Chaumont route.Some 250 to 300 passengers by this train were stopped byM. Dreyfus at the frontier ; among them the Jews were in aminority, the bulk being composed of Germans, Tyrolese,Italians, and even Americans.
