I had been in bed ten minutes, and had not gone to sleep, when he suddenly started up in bed and called out, “Doctor, get up; I am going to be ill; ring the bell for Mr. Palmer.” I rang the bell, and the chambermaid came to the door. He himself called out to her, “Fetch Mr. Palmer.” He asked me to rub his neck. I rubbed the back part of his neck and supported him with my arm while doing so. There was a stiffening of the muscles; a sort of hardness about the neck. Palmer came very soon indeed; two or three minutes at the most. He made the remark, “I was never so quickly dressed in my life.” I did not observe how he was dressed, as I was so engaged. He gave Cook two pills, which he said were ammonia pills. Directly he swallowed the pills he uttered loud screams, threw himself back in the bed, and was dreadfully convulsed. As the pills had immediately before been taken, it certainly could not have been from their action. He said to me, “Raise me up or I shall be suffocated.” The convulsions lasted five or ten minutes. It was at the commencement of the convulsions that he called out to raise him up or he should be suffocated. All the muscular fibres were convulsed; there was a violent contraction of every muscle of the body, and a stiffening of the limbs. When he called out to me to raise him, I endeavoured to do so with the assistance of Mr. Palmer, but found it was quite impossible owing to the rigidity of the limbs. When he found I could not raise him up he asked me to turn him over, which I did. He was quite sensible. After I had turned him over I listened to the action of his heart. I found it gradually to weaken. I requested Palmer to fetch some spirits of ammonia in the hopes of reviving him. Palmer fetched a bottle from his house. He was not away above a minute. When he returned, Cook’s heart was gradually sinking, and life was almost extinct. He died very quietly. He was not able to take the ammonia, and it was very soon after Palmer returned that he died. From the time when he raised himself in bed and called upon me to go for Palmer to the time when he died would be from ten minutes to a quarter of an hour. In my judgment, as a medical man, he died from tetanus, or, in ordinary English parlance, lockjaw. Does it involve, ordinarily speaking, a mere locked jaw?--Yes, that is the common term. Locked jaw is one of the symptoms of tetanus. Every muscle in the body was affected in the same manner.
