<P> Virchow was the first to develop a systematic method of autopsy, based on his knowledge of cellular pathology . The modern autopsy still constitute his techniques . His first most significant autopsy was on a 50 - year - old woman in 1845 . He found from the body an unusual amount of white blood cells, and gave a detailed description in 1847 and named the condition as leukämie . One on his autopsies in 1857 was the first description of vertebral disc rupture . His autopsy on a baby in 1856 was the first description of congenital pulmonary lymphangiectasia (the name given by K.M. Laurence a century later), a rare and fatal disease of lung . From his experience of post-mortem examinations of a number of cadaver, he published his method in a small book in 1876 . His book was the first to describe the techniques of autopsy specifically to examine abnormalities in organs, and retain important tissues for further examination and demonstration . Unlike any other procedure before, he practiced complete surgery of all body parts with body organs dissected one by one . This has become the standard method . </P> <P> Virchow discovered the clinical syndrome which he called ochronosis, a metabolic disorder in which a patient accumulates homogentisic acid in connective tissues and which is indicated by discolouration under the microscope . He found the unusual symptom from an autopsy of the corpse of a 67 - year - old man on 8 May 1884 . This was the first time this abnormal disease affecting cartilage and connective tissue was observed and analysed . His description and coining of the name appeared in the October 1866 issue of Vichows Archiv . </P> <P> Virchow was the first to analyse hair in criminal investigation, and made the first forensic report on it in 1861 . He was called as an expert witness in a murder case, and he used hair samples collected from the victim . He became the first to recognise the limitation of hair as a conclusive evidence . He found that hairs can be different in an individual, and individual hair has characteristic features, and that hairs from different individuals can be strikingly similar . He concluded that evidence based on hair analysis is inconclusive . His testimony runs: </P> <P> (T) he hairs found on the defendant do not possess any so pronounced peculiarities or individualities (so) that no one with certainty has the right to assert that they must have originated from the head of the victim . </P>
