Potato-cultivations.—Sterilised jiotatoes form an excellent medium for the cultivation of many micro-organisms, more especially the chromogenic species. Potato-cultivations also give in some cases very characteristic appearances, which are of value in distinguishing bacteria which morphological resemblances. Preparation of Sterilised Potatoes.—Potatoes, preferably smooth- skinned, which are free from " eyes " and rotten spots, should be selected. If they cannot be obtained without eyes and spots, these must be carefully picked out with the point of a knife. The potatoes are well scrubbed with a stiff brush, and allowed to soak in 1 in 20 carbolic for a few minutes. The}' are then transfei'red to the j)otato-.
