In three or four hours the rod is seen to have almost or completely disappeared, leaving the spore lying free or within the faint outline of the...
Page 634 - This appearance is distinctively characteristic ; and as the growth is very rapid, this method commends itself for making a quick diagnosis of the presence of the bacillus in larvae supposed to be diseased. Potato cultures. — On potatoes the growth differs considerably, according to the reaction and age of the potato.
