It is useful in many cases, as, for instance,for syrup or mucilage bottles. Such a stopper can be readily cleaned,and as it does not stick to the bottle it consequently is not so liable tobreak. 3. As a funnel. Insert a small and short glass tube in the tophole of the nipple, as in Fig. 3. By flanging one end of the tube it isprevented from slipping through. This can easily be done by soften-ing the end

Perforated corksare troublesome to make, the fibng consuming a great deal of time;but in using the nipple all this is avoided. 5. For luting corks on tubulated retorts, as in Fig. 12. Instead of of using linseed fr meal, fenugreekor plaster of Paris,nipples or rubberfinger - cots arevery convenient,as also for pre-venting volatilechemicals, such aschlorine water,sulphurous acidand bisulphide of -carbon, chloroform, ether, etc., from evaporating, after the bottles haveonce been opened for dispensing. 6. For constructing a syphon (Fig. 10), we take a doubly perforatedcork, a, draw a nipple, b, over one end and a short glass tube, c,through the top hole of the nipple, then introduce the bent glass tube,d, for suction, and the short straight glass tube, e, and attach the rub-ber tubbing,/. This completes the apparatus. In using it, close ori-fice of c with finger and suck at d, then at c. My siphonhas gre
