The courts often are accused of being too slow in accepting the benefits of new inventions, but certainly they are not subject to this criticism in regard to the use of X-ray photographs as evidence. Within a year of Roentgen's discovery of X-rays in 1895, radiographs were admitted in evidence in the case of Smith v. Grant tried in the First District Court of Colorado. Ever since then courts have shown little hesitation in permitting the introduction of X-ray photographs in evidence. Today the rule is now firmly settled that with certain definite restrictions X-ray pictures are competent evidence of the internal condition of the human body.
