COTTON.-There has been little business done in Cotton. The sales since our last, little exceed 600 packages-200 Pernambuco were disposed ef at 25. 14d. to 2s. 1 d. 90 Bahias for export 2s. Old. a few common West India 19 d. to 214d. Carolina 234d. 40 Surats 14 d. and 220 Bengals in the bouse 101d. to 114d. The East India Company have not declared any further sales of Cotton. SUGAR-There were no Sugars on shew this morning on account of the holidays. There was a considerable revival in the refined market last week : -after it was ascertained that no new duties would this year be levied in Rus sia, the prices advanced about 2s. the request has since subsided, and the currency may again be stated declining; the purchases had been chiefly low Lumps for crushing, and crushed Sugars. There was less inquiry after Foreign Sugars; no alteration in the prices could be stated. COFFEE-There was only one publie sale of Coffee brought forward last week, it consisted of 84 casks British Plantation Coffee, and 405 bags Brazil description; the quantity of the former was too inconsiderable to form a criterion of the market; it went off, however, freely, at very high prices-good middling Demerara realized 1168. and 116. 6d-405 bags fine ordinary Brazil sold at 106s. and 106s. 6d. after the ale, the demand by private contract was still very limited, and it was reported several rather extensive parcels of Coffee were offered at prices a shade lower; there were, however, few sold. There were no public sales this forenoon, and few are advertised; the demand by private contract appears improving, notwithstanding the holidays. IRISH PROVISIONS.-Prime Mess Beef continues in good demand. Pork in fair request. Bacon remains steady; there is not much inclination evinced to purchase at the present prices. The Butter market has been heavy. RICE. There continues to be a demand for Carolina Rice. East India descriptions also in request. TOBACCO.-There has little business been done in Tobacco since our last; the holders continue sanguine that, from the reduced stock, the present prices will be fully supported; there are scarcely any parcels of Virginia offering under 8d. OILS. The prices of Greenland Oil have again given way considerably. There is no variation in Southern since our last. A vessel with 220 tuns Sperm has arrived, but as the cargo had been previously sold to the trade, it will produce little variation in the market. Seal Oil may be stated at a decline of 21. Rape is also a shade lower. There has been more inquiry for Linseed; the prices are at an advance. Gallipoli is at a small decline. MADDER. By public sale last week, 21 casks French Madder, 105s. to 107s. 161 bales Madder roots 94s. to 95s. damaged 98s. to 90s. 6d. 11 NAVAL STORES. - There is no Rough Turpentine at market; the demand for Spirits continues limited. Little doing in Pitch, Tar, or Rosin. HEMP, FLAX, AND TALLOW.The purchasers of Tallow have been sanguine that the arrivals would be so extensive, that they have for a length of time bought only parcels for immediate use, and as the wind still continuesto the westward, it has entirely prevented the expected supplies; the scarcity of Tallow is now so apparent, that the holders have realized an advance of 2s. to 3s. on parcels here; yesterday 79s. and 80s. for Yellow Candle Tallow was reported to be realized; for arrival there was little variation, 68s. to 70s. being the prices for parcels to arrive during the season. Hemp and Flax are without any variation. RUM, BRANDY, AND HOLLANDS. -The demand for Rum has rather revived; the request appears to be chiefly for Leeward Island Rum for North America; the prices may be stated a shade higher. The inferior descriptions of Brandy may be quoted at a small decline. Geneva without any variation. FROM THE 23D OF FEBRUARY, TO THE 23d of march, 1818, roth inCLUSIVE. BREAD, per quartern..
