    Thiers Improved Instrument for Drawing off MiUc from the Breasts of Women. indented ring N, attached to the lower vessel or reservoir, and in which two notches 0, 0, are made; to facilitate the movement of the hooks behind the ring, a little bolt P, which maintains its position by means of a groove in the upper ring, fastens into one of the notches in the lower vessel or reservoir, 5 which prevents the vessels from turning when they are fastened together; in order to separate the two vessels, the little bolt is drawn back with the nail, and the lower vessel is turned round until the notches come in contact with the hooks, and the hooks are unfastened. The tube I may be soldered either to the upper or the lower ring, as may be preferred. 10 Figure 2 shews the lower vessel or reservoir with the tube or syphon inserted in it, which is used for the conveyance of the milk to the child. It should be noted that in this apparatus there are two vessels, which are either dependant upon or independant of each other, according to the manner in which they are employed; the upper vessel is that which is used for tbe 15 extraction of the milk, the other is merely in sucking bottle appended to it, which sucking bottle is so constructed that any aliment which can be taken in by suction may be administered by means of it to infants. It may be made of any form and of any size that may be desired. The principle of this sucking bottle, and that in which the merit of the Invention consists, is the 20 facility with which children can make use of it by means of the flexible tube, which yields to their movements, an effect admirably suited to their state, as it prevents their being either annoyed or hurt, as they are liable to be in the use of bottles which are made without this flexible tube. Figure 3 shews the most commodious and most pleasing form in which this 25 apparatus may be made; the sides being hollowed, it can be more easily held, and the hand being placed right over the liquid will help to maintain its degree of warmth for a longer time than it would otherwise have done. A stopper of cork, perforated, is screwed into the tin tube, which passes across the cork of the bottle, so that the smaller cork stops up the hole of the larger 30 one, and prevents the liquid from escaping when the vessel is moved in an inclined position. Figure 4 is a more simple form of the apparatus, to allow of its being made and sold at a cheaper rate. The manner of using it differs in this respect, that after the milk is drawn, the apparatus should be removed from the breast, 35 and there should be then introduced, through the hole of the bell or cup, a tube having the same advantages as the tubes which have been already described, namely, partly composed of tin and partly of india-rubber, with a nipple attached to the upper extremity of the india-rubber part of the tube, and which two parts of the tube can, as before described, be united, so as to
