X he experiments and observations on shell and bone, whichI had the honour last year to lay before this learned Society,were made in consequence of my having discovered, some littletime before, that the enamel of teeth did not consist principallyof carbonate of lime, as was generally believed, but was of anature similar to bone; with this difference, that the phosphateof lime was not deposited in and upon a cartilaginous or mem-branaceous substance, but was only blended with a certainportion of animal gluten.* By the experiments subsequentlymade on various shells, crustaceous substances, and bones, itwas proved, 1st. That the porcellaneous shells resemble the enamel ofteeth in the mode of formation, but that the hardening substanceis carbonate of lime. adly.
