Artificial leech with two syringes, patented by Baron Heurteloup. Artificial leeches were a mechanical instrument which superseded the use of real leeches in the practice of bloodletting which carried a greater risk of infection. These mechanical devices were invented due to the shortage and subsequent high prices of live leeches. This set dates from around 1840 and was made in Berlin, Germany. The lining reads, 'G. F. Kittel, Berlin'.
