One bacteriologist, studying several cheeses, separated about eighty different species therefrom, and others have found perhaps as many more from different sources. Moreover, experiments have been made with a considerable number of these different kinds of bacteria to determine whether they are capable of producing normal ripening.
In the, field of original scientific research is the famous bacteriologist, Dr. Kitazato. Less widely known perhaps, but none the less truly original explorers in the field of science, are Messrs. Hirase and Ikeno, whose discoveries of spermatozoids in Ginko and Cycas have no little value for botanists, especially in the development of the theory of certain forms of fertilization.
He was by nature and from his boyhood a devotee of science. For about ten years he practiced his profession, but continued his studies with indefatigable zeal. The investigations of Pasteur had already filled Europe with applause when Koch, following on the same lines of scientific exploration, began to enlarge the borders of knowledge. He became a bacteriologist of the first rank.
Must we however with an eminent bacteriologist declare any explanation of growing old insufficient that does not take account of phagocytosis? We do not feel qualified to settle the question.
If this was the line taken about smallpox, the microbe of which has never yet been run down and exposed under the microscope by the bacteriologist, what must have been the ardor of conviction as to tuberculosis, tetanus, enteric fever, Maltese fever, diphtheria, and the rest of the diseases in which the characteristic bacillus had been identified!
Under these menacing conditions cases of the disease became more numerous and when Col. Strange died of it uneasiness culminated in real alarm. My proposed trip to Scotland for Christmas was postponed and instead I was sent up to London to get an expert bacteriologist on the disease and arrange to start a laboratory.
"Anything more about Challenger?" "Well, I'm a bacteriologist, you know. I live in a nine-hundred-diameter microscope. I can hardly claim to take serious notice of anything that I can see with my naked eye. I'm a frontiersman from the extreme edge of the Knowable, and I feel quite out of place when I leave my study and come into touch with all you great, rough, hulking creatures.
"The manipulation of the tins is quite easy." He conducted us to a small room on the top floor, which I at once saw was fitted as a laboratory, and which contained microscopes, incubators, stands of test-tubes, and all the other apparatus appertaining to the bacteriologist. One of his assistants had carried up four small tins of beef, with a couple of bottles of beef extract.
This method is frequently advisable, since the bacteriologist can seldom hunt up all bacteriological literature with sufficient accuracy to determine whether some other bacteriologist may not have found the same species in an entirely different locality. One bacteriologist, for example, finds some seventy different species of bacteria in different cheeses.
What limits to the frightfulness yet to be discovered by chemist and bacteriologist? What guarantee against the insidious growth of a militarist attitude even in democratically minded peoples if the constant terror of war exalts military preparations to the supreme place? Something has changed the Germany of other days which many of us loved even while we shrank from its militarist masters.
