As to the subsequent use of the laryngoscope in another sphere of investigation, and the far-reaching results which are due to it, it was nearly two years before the possibility of making practical use was seen. The medical profession was slow to realise what an invaluable instrument of observation the musician had provided, and at first it was treated by superior persons as nothing more than a physiological toy; in fact, as so often happens when a discovery is made by some one not belonging to the craft, Garcia's communication was originally received by the doctors with indifference, if not with incredulity. It might have been expected that the uses to which the instrument could be put for diseases of the throat would forthwith have been perceived, and its value as a means of diagnosis appreciated. Yet, but for an accident, the paper might have lain buried in the dusty tomb of the 'Proceedings' of the Royal Society. It is generally said that Türck of Vienna, coming by chance across it two years after the date of its presentation, was inspired to apply the invention to the examination of the upper air-passages. "This," says the 'British Medical Journal,' "is not accurate. Türck had been working independently on much the same lines as Garcia, and had even devised a laryngoscope. He showed the instrument to a friend, who at once informed him that the invention was not new, and directed his attention to the paper in question." Türck continued his experiments for a time; and it was in this year, 1857, that the instrument was actually used for the first time for diagnostic purposes. He seems, however, to have given up his experiments later, owing to the want of sunlight in the winter. Soon after this, Professor J. N. Czermak of Buda-Pesth, another great physiologist, visited Vienna, and was shown the instrument, in which he was keenly interested. With it he made the observations which he published. This fact gave rise to one of those bitter controversies as to priority, of which the history of science offers so many examples. The famous dispute had the immediate effect of directing the attention of the whole world to the laryngoscope. As to the rights of the matter, it would appear that while there is no doubt that Czermak owed his knowledge of the method to Türck and indirectly to Garcia, he made the important modification of substituting artificial illumination for the uncertain light of the sun. One thing is certain, and that is that to Czermak belongs the credit of making known to the world the laryngoscope, and to some extent the possibilities lying hidden in the little mirror. He visited the principal medical centres of Europe, and, luckily being gifted with a capacious and exceptionally tolerant throat, he was able to give convincing demonstrations of the value of the discovery, and its scientific and practical possibilities. If Garcia was the founder, Czermak was the apostle, of laryngology.
