The rôle of the vitamine in the nutrition and growth of organisms other than the man is becoming a matter of interest in various ways. The construction of culture media for various strains of bacteria and the conditions favorable or unfavorable to their growth, are features of study in which the new hypothesis has demanded attention. It has already been claimed that vitamines are essential to the growth of the meningococcus, the influenza bacillus, the typhoid bacillus, the gonococcus, the pneumococcus Type I, Streptococcus hemolyticus, the diptheria bacillus, the Bacillus pertussis and certain soil organisms. If these views are confirmed it becomes evident that the means for prevention of the development of these forms may lie in the control of the vitamine content of the materials on which these forms thrive and that in the study of these types it may be possible to speed up the incubation of strains and thus hasten diagnostic measures by introducing the necessary vitamines into the culture media. These observations merely suggest the possible widening of the scope of the vitamine study in the service of man and give added reason for our keeping pace with the strides made in this particular field.
