The description of one species of bacteria by two different bac- teriologists may vary considerably, as the characteristics of the germs depend so much upon the conditions throughout the classification process. Over 200 different species have been described. It is possible, however, though all of these types may have different morphological and physiological characteristics as described by different bacteriologists, that some two or more of the 200 types may belong to one Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original McKay, George Lewis; Larsen, Christian, 1874-.
