Abstract
MICROSCOPISTS who are hampered by wearing eyeglasses (that is, pince-nez) often find that when their work requires reference to books or other objects on the table, the incessant business of taking their glasses off and putting them on wastes time, and is apt to become wearisome. There is a simple way of getting over the difficulty. When the glasses are taken off in order to make way for the microscope, they should not be laid down but should be kept on the head, in which position, being near the fine adjustment and the hand resting on it, they can at once be replaced when wanted. To attach the eyeglasses in this way nothing more elaborate is necessary than a piece of ordinary elastic, the two ends of which are tied, or fastened with hooks, to the frame, preferably the bridge, of the glasses. With the elastic loop round the head, the eyeglasses can be raised on the forehead out of the microscope's way or brought into position for reading with a minimum expenditure of time and trouble.
