Having now got the complete documentation, I've found that Peter Taylor died 30th January 1852, from a failed amputation of his arm. He had been taken to the Royal Infirmary in Glasgow for the procedure, a relatively new hospital at the time. The amputation was necessitated due to a bite wound to his finger (from his wife Margaret, ostensibly during a vicious argument - hence the culpable homicide charge) that became infected. The witnesses who would have been called up (had the case made it to trial) include many of the broader Taylor family, and I'm not entirely clear on who is who.
