XX1V Obituary Notices of Fellows deceased. 
sharp distinction between the two varieties, though usually manifest, is not 
so absolute as Koch supposed, and that bacilli of the bovine type are not so 
uncommonly found in human infections as he was led to believe. The frank 
expression of opinion by Koch on this subject has been the stimulus for an 
enormous amount of valuable work in connection with tuberculosis throughout 
the civilised world, but the relative importance of infection from one another, 
through sputum, and from bovines through dairy produce, is still an open 
question, and will not be settled for many years to come. 
Before closing this sketch of his life-work, it remains to add a few words 
upon Koch as a teacher. In 1885 he removed from the Health Department, 
and became a professor in the faculty of medicine and director of the new 
Hygiene Institute, attached to the University of Berlin. Here, with the help 
of his assistants, numbers of those who later became the leading bacteriologists 
in all countries were trained in his methods and endowed with some portion 
of his enthusiasm and earnestness. The admiration with which he was 
regarded by his pupils, and the absolute faith which he inspired, amounted 
in many cases to actual worship, and afford further evidence of the essential 
greatness of the man. 
Amongst the numerous honours conferred upon him by scientific and 
academic bodies throughout the civilised world was the Foreign Membership 
of the Royal Society, to which he was elected in 1897. 
There have no doubt been many discoverers as great as Koch, but 1t must 
be seldom that one has been so individually associated with the development 
of a science. Bacteriology has to so great an extent grown up around Koch, 
that the title “Father of Bacteriology” has been conferred upon him by his 
admiring compatriots.
