The present work was undertaken w to relieve the inconvenience arising from the want of a sive treatise. It is based upon a paper of mine published ago in Liebig’s Annalen, Bd. 189, in which I discussed determining specific rotation, and, by way of introduc- a brief general account of optical activity. Since then ave frequently reached me, urging the desirability of that paper by including an account of all the recent ts and the practical applications, so as to make it a complete of the subject. I was the more readily induced to under- sk by the fact that, of late years, the increased attention phenomena of rotation has brought to light such a cts as makes it possible to present the material in a more plete form. theoretical aspect the optical activity of organic substances igh interest. As it is a consequence of peculiarity of arrange- le atoms in the molecule, it must assuredly afford some in determining the constitutional formula to be assigned jstances. The investigation of this connection between tver and chemical constitution is, indeed, of the utmost and gives promise of a rich harvest for future workers. mi
