STRANGE INVENTION
“BLOODHOUND BOX” TRACKING OF CRIMINALS LONDON, 24th January. The “Police Review” gives details of a- strange “bloodhound box,” called a “vancamoscope,” whereby tlie inventor professes that he can pick up the trail of a criminal by tracking an individual scent after a murder, burglary or similar crime. Certain chemicals are sprayed on the spot, and resultant vapours pass into the vancamoscope. There the record of the suspects’s individual scent forms a spectrum band. The magic box is then carried to a track where the criminal is believed to have walked. When the pointer of the vancamoscope shows a spectrum band similar to that recorded it can be assunied that the criminal passed that way. The “Police Review” states that no two persons have the same spectrum record.
