Since the method of treating snakebite-poisoning by hypodermic injections of strychnine, discovered by the writer and published but a few years ago, has already been adopted by the medical profession throughout the Australian colonies, and practised even by laymen in cases of urgency with much success, it has been repeatedly suggested to him that the subject calls for further elucidation at his hands; that the morbid processes engendered by the snake venom and the _modus operandi_ of the antidote should be explained by him in a manner satisfying the demands of science, and at the same time within the grasp of the intelligent, moderately educated layman. When the latter, in a case of pressing emergency and in the absence of medical aid, is called upon to administer a potent drug in heroic doses, the aggregate of which would be attended by serious consequences in the absence of the deadly ophidian virus, an intelligent insight alone into the process he is about to initiate will give him that decision and promptitude of action, on the full exercise of which on his part it may depend whether, within a few hours, a valuable and to him probably dear life will be saved or lost.

The foregoing applies, not to Australia only, but to all other countries infested by venomous snakes. The introduction of the writer’s method in every one of these countries is merely a question of time, for snake-poison acts everywhere according to one uniform principle, however different the symptoms it produces may appear to the superficial observer. The antidote, therefore, that cures snakebite in Australia will as surely cure it elsewhere if properly and efficiently applied.

To his Australian confrères, more especially to those who adopted his method but had to practise it more or less empirically, the writer also owes a more elaborate explanation of his theory of the action of snake-poison in all its bearings on the various nerve centres than is to be found in the scattered writings he has from time to time published in our periodical literature. His warmest thanks are due to them for the records of cases they have furnished to the _Australasian Medical Gazette_, and to the Hon. J. M. Creed, its able editor, for the ample space he has invariably allotted to the subject, and the valuable support he has given him throughout. By our united efforts we have reared in a dark and hitherto barren field of research a column of solid knowledge, and on this column Australia now occupies the highest and will ever occupy the most prominent place.

Not the least pleasing feature in the history of this discovery is the fact that it has been made without an elaborate series of experiments on animals, that it is a peaceful conquest not attained by means of doubtful justification, and which have hitherto invariably failed in their object. This object–the discovery of the coveted antidote–instead of being brought nearer, was, in fact, further removed by every succeeding series of experiments. However fruitful in results this mode of research has been in other domains, in this particular one it has not only been a failure but an actual bar to progress. Nature invariably refused to yield her secret when thus interrogated. The tortured animals, like the victims of Torquemada, either did not answer at all or they answered with a lie, and the baffled experimenter abandoned his task in despair.
