Akn Arbor Jan SO, 1846. A changa in the weather has caused the sleighing of lnst week to disappear, and mud begins to be abundant. Most kinds of business are dull. In the VV heat market the operationsarelight. We quote 80 to 83 cents as the market prices. The Foroign News, which has been so long expected, hns not been as favorable as many anlieipated. it will be seen ihat the supplies f rom the Continent for the EngÃ¼sh market had been extensÃ¯ve, and the rot in the Potatoe erop had been oxaggerated. The BntishCorn Laws are not yet repenled, nor is there any very great prnbability thnt they will be; nor, Ã¯f thoy should be, is it at all certain that the result would authorize the pay'ing of high prices for Wheat immediately. Henee we judge that the present arriyal will not afiect the market materi' ally one way or the other.
