The nitro group in the 2'-position in the case of 31-methy21-nitrocamphoranilic acid lowers the rotation accompanied by a reversal of sign but the effect is not so marked as in the case of 4'-methyl-2'-nitrocamphoranilic acid (J. [...] The OCH3 group in the W-position lowers the values but the effect is not so marked in 2' : 5'-dimethoxas in the case of the 2'-methoxycaphoranilic acid. [...] The only precaution that was necessary was that the acid solution of the amino compound was treated with excess of pounded ice and the nitrite solution was added all atonce. [...] In order to determine the conditions of the experiment the authors reduced anthraquinone-13-carboxylic acid through the chloride into anthraquinonefl-aldehyde by the method of Rosenmund and his cworkers (Ber. [...] The flask containing the mixture was evacuated by means of a waiter-pump until the solution began to boil and then connected with a gas holder containing pure hydrogen and shaken mechanically until the theoretical amount of hydrogengYNtHESIS OF ALOE-EMODIN 377 was absorbed which in this case took only five minutes The catlyst was then removed by filtration the alcohol evaporated off and the
