Abstract
IT would be interesting to know how much time is annually expended in chemical laboratories in the preparation of carbon compounds, already recorded in the literature, but which their would-be discoverers believe to be new substances. The considerable waste of energy involved will, however, appear small if compared with that resulting from the choice of the less suitable methods of attack of a denned problem in organic synthesis. It cannot be said that existing safeguards, Beilstein, Richter, Stelzner, Meyer-Jacobsen, and the general indexes, are sufficient to protect us from these dangers.
