CALCULARY of a Pear, a congeries of little strong knots dispersed through the whole parenchyma of the fruit. The calculus is most observed in rough-tasted or chock-pears. The knots lie more continuous and compact together towards the pear where they surround the ACETARY. About the stalk they stand more distant; but towards the cork, or stool of the flower, they still grow closer, and there at last gather into the firmness of a plumb-stone. The calculus is no vital or essential part of the fruit; the several knots whereof it consists being only so many concretions or precipitations out of the sap, as we see in urines, wines, and other liquors.
