The question whether a person who has apparently committed suicide could possibly have made use of the degree of force to which circumstances pointed has frequently arisen.

The most notable instance of the kind was in reference to the Earl of Essex who was found dead in the Tower in July, 1683, his throat having been cut. A razor was lying by his side with its blade notched, and public opinion was strongly divided as to whether he had committed suicide or had been murdered. The medical men who supported the former view explained the notches upon the razor blade as the result of its having been drawn backwards and forwards across the neck bone, although for a suicide to have done this would have been an impossibility.

Occasions have arisen where a chemical expert has been asked to state whether a gun or pistol found lying near a body has or has not been recently discharged.

Even in the case of firearms that had been loaded with black powder no very definite answer can usually be given to this question. Taylor suggested that the presence of potassium sulphide (formed from the powder) adhering to the barrel would indicate that the gun had recently been fired, whereas after a short time this sulphide would become oxidised, and no longer give the reactions of a sulphide. After a longer time traces of iron oxide formed from the iron of the barrel might be expected.

It would not be safe to lay stress upon conclusions based upon such data as these, and at best they could only afford corroborative evidence.

An amusing instance within the present writer’s experience affords another example of the way in which a trifling point being overlooked may be strong presumptive evidence of attempted fraud. A family of the name of, say, Abendessig, effected an insurance against burglary with a company which may be described as the Safeguard Assurance Co.

It was not long before they were the unhappy victims of a burglary in which Miss Abendessig lost several valuable pieces of jewellery including a watch, a diamond ring, and several brooches.

In proof of her claim she produced receipts from the jeweller from whom she stated she had bought these articles, the total value of which was given at £150.

There were three receipts in all, dated at intervals of two or three months, the first being made out to Miss Abendessig and the last to Mrs. Lab, she having been married in the interval, and the second to her father, Simeon Abendessig.

The Safeguard Assurance Co. had a suspicion that the jeweller, who had an address but no shop, was in league with the Abendessigs, and that the first and third receipts had been written at the same time.
