The respirations finally become exceedingly slow, and then cease, convulsions and death following. It sometimes happens, as in mammals, that the respiratory centre is almost simultaneously stimulated and paralysed, the bird dying at once.
In the amphibia, there can scarcely be said to be any symptoms of cobra-poisoning; the frog, for instance, only becomes more and more sluggish and paralysed, and is at last found to be dead.
It will be necessary to consider some of the more important conditions in detail, after having noticed the appearances to be found after death.
