Abstract
IN a recent communication to the Arbeiten ties botan isches Institut in Würzburg (Bd. iii.), Prof. Sachs gives the results of his work during the past summer in connection with the above subject. The investigations were made with the object of determining the formation and disappearance of starch in the leaves of plants growing in the open, and under normal conditions of vegeta-tion, and were carried on chiefly during the months of June, July, and August on a large number of Dicotyledons from various families. Some twenty-two years ago Prof. Sachs showed that the presence of starch in chlorophyll grains can readily be detected by means of the now well-known iodine test, a modification of which was employed in these researches.
