The peduncle, which was about six times the length of the shell, being encased in a sand tube differing in no respect from the sand tubes of neighboring annelids. In many instances the peduncle was broken in sifting them from the sand, yet the wound was quickly healed and a new sand-tube promptly formed. When placed on the surface of the sand they were noticed to move quite freely, by the sliding motion, in all directions, of the dorsal and ventral plates, aided...
Стр. 164 - Experiments on itacolumite (articulite), with the explanation of its flexibility and its relation to the formation of the diamond.
Стр. 147 - The actual direction in the plant is from the apex of the leaf in sunlight and toward it in the shade.

Стр. 163 - It was distinctly and regularly ringed, and presented a remarkably worm-like appearance. It had layers of circular and longitudinal muscular fibre, and coiled itself in numerous folds or unwound at full length.
