(From the same). Crystal-lines. Also crystalli. The Italian physicans call them taroli. They are pustules filled with water, transparent, and on that account receive their name.

They arc lodged on the prepuce without pain; and, though caused by coition, are not infectious. The cause is supposed to be a contusion of the lymphatic vessels in the part affected. Dr. Cockburn, who hath described this case, recommends for the cure a mixture of three parts of lime water and two of rectified spirit of wine, to be used warm as. a lotion, three times a day.
