he hands of children. But a list of experiments, and of the things necessary to try them, might easily be drawn out by a chemist who would condescend to such a task; and if these materials, with proper directions, were to be found at a rational toy-shop, parents would not be afraid of burning or poisoning their children in the first chemical lessons. In some families, girls are taught the confectionary art; might not this be advantageously connected with some knowledge of chemistry, and might not they be better taught than by Mrs. Raffeld or Mrs. Glass?[5] Every culinary operation may be performed as an art, probably, as well by a cook as by a chemist; but, if the chemist did not assist the cook now and then with a little science, epicures would have great reason for lamentation. We do not, by any means, advise that girls should be instructed in confectionary arts, at the hazard of their keeping company with servants. If they learn any thing of this sort, there will be many precautions necessary to separate them from servants: we do not advise that these hazards should be run; but if girls learn confectionary, let them learn the principles of chemistry, which may assist in this art.[6] Children are very fond of attempting experiments in dying, and are very curious about vegetable dyes; but they can seldom proceed for want of the means of boiling, evaporating, distilling, and subliming. Small stills, and small tea-kettles and lamps, would be extremely useful to them: these might be used in the room with the children's parents, which would prevent all danger: they should continue to be the property of the parents, and should be produced only when they are wanted. No great apparatus is necessary for showing children the first simple operations in chemistry: such as evaporation, crystalization, calcination, detonation, effervescence, and saturation. Water and fire, salt and sugar, lime and vinegar, are not very difficult to be procured; and a wine-glass is to be found in every house. The difference between an acid and alkali should be early taught to children; many grown people begin to learn chemistry, without distinctly knowing what is meant by those terms. In the selection of chemical experiments for young people, it will be best to avoid such as have the appearance of jugglers tricks, as it is not our purpose to excite the amazement of children for the moment, but to give them a permanent taste for science.
