His pupils, contracted each to a dot, became the central puncta of two rings of fiery light; his little sharp teeth seemed to gnash.

XVI. 8; yet the quantity of tears secreted at once is more than the puncta lacrymalia can readily absorb; which shews that the motions occasioned by associations are frequently more energetic than the original motions, by which they were occasioned.

There was the famous Puncta, or diamond arrow, given by Duchess Beatrice's grandfather, Niccolo d'Este, to Francesco Sforza; and the Caduceus, a favourite device of the Moro's, wrought in large pearls, each of which was said to be worth 25,000 ducats; while the balass ruby, known as the Marone, often worn as a brooch by Beatrice, was valued at 10,000 ducats.

Thus the catarrhal humour from the nostrils of some, who ride in frosty weather; and the tears, which run down the cheeks of those, who have an obstruction of the puncta lacrymalia; and the ichor of those phagedenic ulcers, which are not attended with inflammation, are all instances of this circumstance.
