It is to be remarked, that the locked jaw did not take place in those cases in which the wounds had a foul and gangrenous appearance more than others; for those that digested and cicatrized favourably, were equally apt to be affected by it; and though amputations are most liable to this symptom, the slightest injuries, even a scratch, will sometimes bring it on. It would be difficult, therefore, to establish any particular treatment that would tend to prevent accidents of this kind; but Mr. Bassan, surgeon of the Arrogant, one of the line-of-battle ships engaged on the 12th of April, mixed laudanum with the dressings of all the wounds, and no locked jaw occurred. In the Bedford there occurred a curious circumstance concerning this complaint. In one of the cases that proved fatal, the symptoms did not come on till the wound was so far healed that all dressing had been laid aside. Mr. Wood, surgeon of the hospital at Jamaica, informed me, that in cases of the locked jaw from injuries to small members, such as fingers, he had tried the effect of amputating the part after the symptoms had come on, but without any effect in putting a stop to them. Would it not appear, from the two last mentioned facts, that this symptom is not kept up, nor even takes place in the first instance, from an immediate present irritation, but that the constitution comes to be so modified, or receives such an impulse, as it were, that the complaint runs its course independent of the presence of that _stimulus_ which excites it?
