and from his description of suchcases I feel justified in speaking of intumes-cence of Tomato leaves. Professor Sorauerrefers to the frequency of such intumescences on Cassia tomentosa. The young leaves did notstraighten themselves as in normal conditions,and distinct swellings of the central leaf-ribcould be detected. On microscopic examinationhe found abnormal elongations of the cellsbeneath the epidermis, which in portions hadburst through it. At the same time he observedthe position of the chlorophyll in such cells, andstates that most of the chlorophyll bodies arefound at the base of the cells still in sitn,slightly yellowish, and somewhat eaten away.
