In a recent communication of this series (XXVI), it was contended, that the change in the optical rotatory power of an aqueous solution of fructose which is produced by dissolving in the liquid a second substance, whether this be a salt or a non-electrolyte, is the consequence of an alternation in the proportion in which the two isodynamic forms of the compound are present in equilibrium. It was shown that substances such as the monhydric alcohols cause the change to take place in a direction opposite to that in which it takes place when substances such as sugar and salts are added: a similar antithesis has been observed in the course of these studies in numerous other cases in which the influence exerted by interfering agents has been determined. To obtain sufficient data fro the discussion of this problem, we have not only verified the results previously put forward, by repeating the observations and eliminating unsuspected sources of error, we have also measured the effect of a large number of substances other than those used previously.
