In the vomit and intestinal contents of the attackedthe comma forms are always present for a number of days, and short andincomplete spirils may sometimes be demonstrated in smear-preparations. The comma bacillus of Koch multiplies commonly by two modes, each ofwhich, however, constitutes essentially a process of fission: a, the commadoubles its length, and then divides into two ; 6, before dividing the commacontinues its elongation into a longer or shorter spiril filament, which ulti-mately becomes segmented in order that finally the segments may separate toform new and separate commas. Of these two processes of multiplication, theformer is by far the more rapid. Elongation and division of the one commainto two have been actually observed under the microscope to take place intwenty minutes. With such a rate of multiplication demonstrated, one caneasily form some adequate conception of the otherwise inconceivable rapidity of PLATE IX
