Witness.—“No doubt there was spasmodic action of the muscles, but not idiopathic or traumatic tetanus, because the sudden onset of the spasms, and their rapid subsidence, are consistent with neither of the two forms of tetanus.”
Question.—“Is there not hysteric tetanus?”
Witness.—“Yes: it is rather hysteria combined with spasms, but it is sometimes called hysteric tetanus. I have known no instance of its proving fatal, or of it occurring to a man. Some poisons will produce tetanus. Nux vomica, acting through its poisons, strychnia and brucia, poisons of a cognate character, produce that effect. I never saw human or animal life destroyed by strychnia.”
In his cross-examination, Mr. Curling admitted that irritation of the spinal cord, or of the nerves proceeding to it, might produce tetanus, and the correctness of Dr. Watson’s statements in his Lectures, that, in four cases out of five, the disease begins with lockjaw, and that all the symptoms of tetanic convulsions may arise from very trivial blows; but he denied that there was any well authenticated instance of “traumatic tetanus” occurring within a quarter of an hour after the reception of the injury, or that it was very likely that the irritation of a syphilitic sore by wet, cold, drink, mercury, or mental excitement, might lead to tetanic symptoms.
“The irritation,” said Mr. Curling, “which is likely to produce tetanus is the sore being exposed to friction, to which syphilitic sores in the throat are not exposed. I should class tetanus arising from the irritation of a sore as traumatic. Cases very rarely occur which it is difficult to class as either traumatic or idiopathic. I should class tetanus arising from irritation of the intestines as idiopathic. The character of the spasms of epilepsy are not tetanic.”
Serjeant Shee.—“Not of the spasms; but are not the contractions of epilepsy sometimes continuous, so that the body may be twisted into various forms, and remain rigidly in them?”
Answer.—“Not continuously.”
Question.—“For five or ten minutes together?”
Answer.—“I think not.”
Question.—“Does it not frequently happen that general convulsions, no cause or trace of which in the form of disease or lesion is to be found in the body after death, occur in the most violent and spastic way so as to exhibit appearances of tetanic convulsions?”
