The substance called Cuttle-bone, from the back of the Cuttle-fish (Sepia officinalis, Linn.)] 82. Calcareous earth. [The shell of a Cowry (Cyprsea Tigris, Linn.), consisting almost entirely of carbonate of lime.] Series VIII. Structure and Growth of Shell. Shell is a substance made use of chiefly as a defence from external accidents ; serving the purpose of a retreat, as in univalves, bivalves, and so on; but in some Insecta, it not only answers this purpose of external covering, but serves as levers on which the muscles may act so as to bring about progressive motion, and makes an instrument analogous in some measure to a hand, or to teeth ; as, for example, in the claw of the lobster, where it is constructed so as to lay hold of and pinch whatever molests it. Hunterian MS. Catalogue. 1. In Zoophytes. 82 a. A Madrepore (Meandrina areolata, Lam.), the lower part of which has been steeped in dilute muriatic acid, and partially dissolved. The traces of animal matter are hardly to be perceived. Prepared in 1831. 82 b. A Madrepore (Caryophyllia Cyathus, Lam.), the upper part of which has been similarly treated. Prepared in 1831. 82 c. A portion of Caryophyllia sinuosa, Lam., which has been similarly treated, and exhibits the animal constituent sufficiently organized to preserve the membranaceous form, and in some degree the foliated cha- racter of the Madrepore. Prepared in 1831. 82 d. A Madrepore (Oculina hirtella, Lam.), similarly treated, and exhibiting a greater proportion of animal matter; probably, however, from having been incrusted with some sponge. Prepared in 1831. 82 e. A Coralline (Dichotomaria, Lam.), the terminal joints of which have been subjected to the action of dilute muriatic acid, and reduced to their d 2](https://iiif.wellcomecollection.org/image/b22007763_0001_0039.jp2/full/800%2C/0/default.jpg)
