ALDBOROUGH , a See also:

village in the See also:Ripon See also:parliamentary See also:division of the See also:West See also:Riding of See also:Yorkshire, See also:England, 16 m. W.N.W. of See also:York, and 1 m. E. of the See also:market See also:town of See also:Boroughbridge, which has a station on a See also:branch of the See also:North-Eastern railway. Aldborough formerly returned two members to See also:parliament, but was disfranchised by the Reform See also:Act of 1832. The See also:place is remarkable from its numerous See also:ancient remains. It was the Isurium Brigantum of the See also:Romans, originally perhaps a See also:capital of the See also:Brigantes tribe, and afterwards a Romano-See also:British town of considerable See also:size. See also:Inscriptions, beautiful mosaics and other traces of comfortable houses have been found, with many potsherds, coins and See also:bronze, See also:iron and other See also:objects; and a large See also:part of the town walls, several mosaics and parts of buildings, can be seen.' A See also:fine collection is kept in the Museum Isurianum in the grounds, of The See also:aldehydes may be prepared by the careful oxidation of See also:primary See also:alcohols with a mixture of See also:potassium dichromate and sulphuric See also:acid,—3R•CH2OH+K2Cr207+4H2S03=K2S0,+ Cr2(SO.03+7H2O+3R•CHO; by distilling the See also:calcium salts of the fatty acids with calcium formate; and by See also:hydrolysis of the acetals. L. Bouveault (See also:Bull. See also:sac. shim., 1904 [31,31,p.1306) prepares aldehydes by the See also:gradual addition of 'disubstituted formamides (dissolved in anhydrous See also:ether) to See also:magnesium alkyl haloids, the best yields being obtained by the use of diethyl formamide. Secondary reactions take place at the same See also:time, yielding more particularly See also:hydrocarbons of the See also:paraffin See also:series. G. Darzens (Comptes Rendus, 1904, 139, p.

1214) prepares. See also:

esters of disubstituted glycidic acids, by condensing the corresponding ketone with monochloracetic ester, in the presence of See also:sodium ethylate. These esters on hydrolysis yield the See also:free acids, which readily decompose, with loss of See also:carbon dioxide and formation of an aldehyde, the See also:manor-See also:house.
