In respect to the preserved meats at the Great Exhibition, many were merely cured or dried meats. From Canada, for instance, they comprised hams, bacon, tongues, and barrels of beef and pork. Among the miscellaneous contributions were grated beef, canisters of fresh salmon, 'admirable boiled mutton in tin cases,' dried mullets, '_mouton roti_,' fish, meats preserved in a fresh state by simple drying--on a plan practised in Switzerland--and preserved larks. Not the least remarkable was a preserved _pig_, which reclined in all its glory on the floor of the south-west gallery, and was a successful example of curing on a large scale. Still more striking than this, was the large partridge-pie, placed somewhat out of general notice in the 'Netherlands' department; a formidable pie it truly was, for it contained 150 partridges, with truffles, and weighed 250 pounds: it had been made a year before it was forwarded to London. But among the contributions more immediately relating to our present subject, may be mentioned those of Mr Gamble, which comprised, among others, a canister of preserved boiled mutton, which had been prepared for the arctic expedition in 1824; many such canisters were landed at Fury Beach in Prince Regent's Inlet; they were found by Sir John Ross at that spot in 1833 in a perfect state, and again by Sir James Ross in 1849, the meat being as sweet and wholesome as when prepared a quarter of a century before. The range of these preserving processes is singularly wide and varied. If we take the trade-list of one of the manufacturers, such as that of Messrs Hogarth of Aberdeen, and glance through it, we shall find ample evidence of this. There are nearly twenty kinds of soups selling at about 2s. per quart-canister. There is the concentrated essence of beef, much more expensive, because containing the nutriment of so much more meat; and there are, for invalids, concentrated broths of intermediate price. There are about a dozen kinds of fish, some fresh and some dried. There are various kinds of poultry, roast and boiled; hare, roast and jugged; and venison, hashed and minced. There are beef, veal, and mutton, all dressed in various ways, and some having the requisite vegetables canistered with them, at prices varying from l0d. to 15d. per pound. There are tongues, hams, bacon, kidneys, tripe, and marrow; and there are cream, milk, and marmalade. Lastly, there are such vegetables as peas, beans, carrots, turnips, cabbage, and beet, at 6d. to 1s. per pound-canister. The canisters for all these various provisions contain from one pound to six pounds each. It was Messrs Hogarth, we believe, who supplied the preserved meats and vegetables to the arctic ships under Sir E. Belcher which sailed in the spring of 1852.
