This procedure must be carefully done, lest adifferent colony be disturbed than the one looked at, and anunknown or unwanted germ obtained. After the needle has entered the particular colony, it iswithdrawn, and the material thus obtained is further exam-ined by staining and animal experimentation. The bacteria. / §- \ •I >
