Excerpt: Lastly, an experiment was made with iodine; of this two cubic centimetres of an alcoholic solution were taken, containing 06 gramme of iodine (equal to about nine-tenths of a grain), a much larger quantity than that ordinarily employed, in consequence of the irritating nature of the fumes. The alcohol through which the air issuing from the trachea was passed, did not become coloured in the slightest degree, nor did it furnish any evidence whatever of the presence of iodine. This experiment was performed a second time with another sheep's head and neck. The saliva of the mouth, and the mucus, were also tested for free iodine; not a trace was present, but, after the addition to the mucus of a little dilute nitric acid, it was freely liberated. This shows that the iodine had really entered the mouth, but had become converted into an iodide, of course losing in the process much of its antiseptic properties. In this respect the experiment accorded exactly with what has elsewhere been shown to take place in the living human subject. Of course it may be urged in objection that the results of the experiments just recorded would have been different in the case of the human subject; and this is to some extent possible, although scarcely probable, seeing that the construction of the larynx of the sheep is less complicated than that of the human subject, and that the passage is much more open and free. However this may be, the experiments are confirmatory of those previously quoted, and they show that substances of little volatility at ordinary temperatures, such as car...
