DUST AS EVIDENCE.
Microscopic examination of the dint and dust upon the clothing of suspects is a new scheme of the French police to catch criminals. After. cross-examination the suspects are stripped of their clothing, whose superficial dust, is first examined under a strong microscope. A vacuumcleaner is next applied to draw out other dirt into a pan. In some instances a. more thorough process, in which heating figures, is used to separate aill particles-' of foreign matter. From the dirt thus secured the detectives determine whether the suspect has been telling the truth. One murderer tried to prove an alibi by saying that he had slept in an open field the night of the crime. Microscopic examination of his clothing showed that he had slept in a quarry An unsuspected carpenter was connected with a murder by means of sawdust found on a piece of overall which the victim had torn from his assailant and which, was found at the scene of the crime. The chief value of the new plan has been in breaking down the bravado of criminals. They frequently confess when shown that- their first stories were lies.
