Stroschein, Snellen, and others havebusied themselves considerably with the improvement ofdropping bottles. As Stroscheins bottle did not suit usaltogether, Sidler-Huguenin devised one which presentscertain additional improvements, the most important ofwhich is the extra width of the mouth, so that in puttingthe pipet back in the bottle there is less danger of strikingthe point against the lip or even the outside of the bottle,an accident that is apt to happen with any dropping bottlehitherto devised. As the outside of the bottle cannot bekept absolutely clean while it is in use, it is always pos-sible that the point of the pipet may be polluted by. 61 <; EN ERA L COS SID ERA TIOXÜ. coming in contact with it and may thus contaminate thesolution, so that the latter very soon ceases to be freefrom germs. It should also be impossible for the contents of thepipet to get up into the bulb when the former is accident-ally reversed, as very often happens with the attendants,and is very difficult to prevent. This requisite is alsofully satisfied by Sidlers dropping bottle. The bulb isprovided with a spiral tube (see ), so that the fluid can not get upinto it from the dropper, no matterhow often it is held upside down. These bottles may be sterilized, alarge number at a time, with steam,as, for example, in Budenbergs ap-paratus ; or the bottle may be placedover a flame, with a piece of wirescreen to prevent cracking, and usedfor boiling the contained either case a small glass rod isplaced between the bottle and thepipet to prevent the latter from act-ing as a stopper.
