Bacteriology. 630 APPLICATION OP METHODS OF BACTERIOLOGY with a stopcock on the cyUnder, or to a glass tube tightly fixed in the neck of an aspirating-bottle by means of a perforated rubber stopper. The cotton plug is then moved from the upper end of the aerobioscope, and the desired amount of air is aspirated through the sugar. Dust-par- ticles and bacteria will be held back by the sugar. During manipulation the cotton plug is to be protected from con- tamination. Fig. 113. Bent funnel for use with aerobioscope.

When the required amount of air has been aspirated through the sugar the cotton plug is replaced, and by gently tapping the aerobioscope while held in an almost horizontal position the sugar, and with it, the bacteria, are brought into the large part (e) of the apparatus. When all the sugar is thus shaken down into this part of the apparatus about 20 of liquefied, sterilized gelatin is poured in through the opening at the end c, the sugar dissolves, and the whole.
