Apatite, the phosphate with fluoride of lime, crystallizes insix-sided prisms terminated by hexagonal pyramids, or in itsmore aberrant and beautiful forms in short prisms variously mod-ified on terminal edges. Examples of much complexity havebeen described, notably amongst which are the crystals fromNorth Carolina detected by Hidde
