~In the first place it possesses a delicious flavour and aroma, altogether lacking in the ordinary vinegar.~ Agreeableness of taste and smell are to a large extent dependent upon the substance from which the vinegar is manufactured, and it is impossible to supply these artificially. That the malt vinegar manufactured in this country is conspicuously wanting in these qualities must be a matter of general experience. Moreover, owing to its great cheapness, acetic acid distilled from wood (besides being employed for pickling and other purposes, for which it is well adapted), diluted and treated with volatile oils, is every year superseding to a larger extent the vinegars in general use. That this bears no comparison as regards the agreeable qualities, even with the ordinary vinegars, need scarcely be pointed out. On the other hand, +Honey+, of all saccharine substances, containing as it does all the essentials for harmonious bouquet and flavour, is the one ~par excellence~, from which we might expect to produce an ideal vinegar. The result is found amply to justify the anticipation, and that its superiority in this respect will be duly appreciated by the connoisseur in salads and condiments goes without saying; but, indeed, so marked is this distinction that I venture to think it would be readily admitted by all who gave it a trial. ~On the ground of wholesomeness honey vinegar is to be preferred.~ It has been clearly ascertained that large quantities of vinegar sold in this country contain injurious adulterants and impurities. Many samples, upon analysis, have been found to include a considerable percentage of sulphuric acid, or nitric acid, added either as a preservative or to increase the acidity. Others have contained, as the results of carelessness in manufacture, such poisonous ingredients as copper, arsenic, and lead. Little wonder that disagreeable consequences so often follow the taking of vinegar, even in small quantities! Immunity from these impurities and adulterants, producing as they so frequently do injurious effects, especially in the case of invalids, is surely greatly to be desired, and every possible improvement, either in respect of the material employed or in the process of manufacture of so important an article of consumption, surely deserves to receive the most careful attention.
