Abstract
The accumulated total of human knowledge is incomprehensible. A few hundred years ago an aspiring scientist took all knowledge as his province, but the ever mounting mass of information necessarily led to specialization. The inevitable penalty of working in a restricted field is ignorance of progress outside one's special domain until some significant overlapping necessitates inquisitive excursions abroad. The possible relation between deficiency of vitamin B and at least some forms of nerve deafness, pointed out by Selfridge,1 and an attempt to alleviate a condition heretofore largely intractable entail certain questions which must be answered if therapeusis is to have some semblance of rationality. What is the chemical and biologic nature of this complex catalyst? Can a symptomatic picture be formulated so that the need for it can be diagnosed clinically ? Are there any laboratory procedures to aid investigators? What are the meanings of the new names and standards
