The judge gave it as his opinion that the case amounted only to excusable homicide, and the man was acquitted.

In forming an opinion as to the cause of death in doubtful cases of suicide, the following important points ought to be carefully kept in view:—

1st. If the person had for some time laboured under melancholia; had met with losses, disappointments, or had suffered any acute chagrin.[74] 2nd. If any of his family, associates, or connexions, had any interest in his death. 3rd. The season of the year should be taken into consideration; for we have observed, without being able to assign the reason, that suicide is more frequent during the solstices and the equinoxes. 4th. If the patient, instead of complaining, remains quiet, seeks for solitude, and refuses medical aid. And 5th. If there be any writing (as those who destroy themselves ordinarily express their last opinions or will) it will be one of the most satisfactory proofs that they have made away with themselves. Remains of poison found in their pockets, or in the apartment, are but an equivocal proof, and one which may attend upon homicide as well as on suicide.[75]

In the course of judicial investigations, medical men are frequently called upon to decide in cases of suspicious death whether wounds discovered on the bodies of the deceased were self-inflicted. Before deciding questions of this character, the medical witness ought to take into consideration the following points:—1st, The situation of the wound; 2nd, its nature and extent; 3rd, the direction of the wound; and 4th, the moral circumstances connected with the case.

Generally speaking, those who commit suicide do not wound themselves on the posterior parts of the body; therefore injuries detected in such situations naturally excite suspicions as to the mode of death. The throat and chest are commonly selected when cutting instruments are used. When death has resulted from the discharge of a weapon introduced into the mouth, Dr. Smith says it may be taken for granted that the case is one of suicide. It is, however, possible, even under such circumstances, for a person to be assassinated in this way. When death has been caused by firearms, the fingers and hands of the deceased should be carefully examined, in order to detect the presence of discoloration. In several instances, a murder has been discovered by a careful examination of the wadding. In two cases on record, the wadding being examined, it was discovered to have been torn from paper found in the possession of the parties on whom suspicion had rested.

Some time back, the body of a man was found lying on the high-road. The throat was severely cut, and he had evidently died from hemorrhage. A bloody knife was discovered at some distance from the body; and this, together with the circumstance of the pockets of the deceased having been rifled, led to a suspicion of murder. This idea was confirmed when the wound was examined. It was cut, not as is usual in suicide, by carrying the instrument from before backwards, but as the throats of sheep are cut. The knife had passed in deeply under and below the ear, and had been brought out by a semi-circular sweep in front, all the great vessels of the neck, with the œsophagus and trachea, having been divided from behind forwards. The nature of the wound rendered it at once improbable that it could have been self-inflicted; and it further served to detect the murderer, who was soon afterwards discovered, and executed.

With reference to the extent of the wound, the celebrated Earl of Essex’s case has often been quoted. He was found dead in the Tower, in 1683, and it was the generally received opinion that he had been murdered by persons hired by the Duke of York, afterwards King James II. Upon examining the wound, it was found that the jugular vessels, trachea, and œsophagus, were cut through to the very neck-bone. The verdict was suicide. In 1688, the matter was revived, and before a committee of the House of Lords,[76] it was proved that the razor with which the wound was inflicted was found on the left side of the body, while it was known that the Earl was left-handed. The edge of the razor was found notched; and it was also proved that the cravat worn by the deceased was cut through, and his right hand was wounded in five places.

As there was much political feeling mixed up with this case, it was difficult to arrive at the truth. That many persons who have cut their throats have divided the neck to the vertebræ is a well-known fact. In the case of Mr. Calcraft, all the large vessels in the neck were divided, and the throat was cut through to the vertebral column.

In the case of Sellis, much stress was laid by Sir E. Home on the wound being regular; he observes, “any struggle would have made it irregular.” Although there were points connected with this remarkable case which naturally tended to excite suspicion, we cannot but declare that the Duke of Cumberland most clearly vindicated himself from the foul charge which party feeling and private malevolence had endeavoured to establish against him.

Many doubtful cases may be decided by taking into consideration the moral circumstances connected with them. A girl was discovered dead. Suspicion rested upon her mother, who had severely beaten the child. It was, however, clearly proved that the girl had been repeatedly heard to declare her intention to commit suicide. Persons should be examined as to the state of mind of the party found dead; whether he or she laboured under an hereditary predisposition to suicidal insanity, or had been exposed to the influence of causes likely to cause melancholy or a depressed state of feeling. If all these points be carefully considered, a fair conclusion may be arrived at in the majority of cases that occur, and which are made the subject of judicial investigation.
