In many objects, such as lymphcorpuscles, corneal cells, and the epithelial cells of gills of Sala-mander larva?, no nuclei can be distinguished during life, althoughthey immediately become visible when coagulation, induced eitherby the death of the cell, or by the addition of distilled water orweak acids, occurs. In many kinds of cells, and in the lower organisms, the nucleusmay assume very various shapes. Sometimes it is in the shape ofa horse-shoe (many Infusoria), sometimes of a more or less twisted. B
