- Abstract
The article cites a paper by C.T. Symons, Government Analyst of Ceylon, that appeared in the November 8, 1935 issue of the journal "The Police Chronicle." The paper describes a technique which was used in the identification of samples of copper wire. Symons states that the procedure was successfully employed following several thefts of government-owned telephone wire, comparisons being made of standard government samples, samples of wire found in the home of the suspects, and samples from the source from which the accused stated their wire had been obtained. The composition of the various samples was determined by spectrographic analysis which revealed the presence of impurities in the government wire not found in the other wires examined. However, it was found necessary, according to the Symons, to determine whether a particular length of wire had been cut down from a particular section of the line. In order to examine two pieces of wire suspected to have come from the two sides of one cut, a comparison microscope was used to bring the two objects optically side by side, in the same way as such an instrument is used in the comparison of rifling marks on bullets.
