Other cases: 



1. Wiirzburg Pathol. Coll., No. 75. Three figures of the skeleton of this 



fetus are given by Forster, I. c, Taf. VI, Figs. 5-7, and show a con- 

 dition almost identical with that of Fenn's fetus. 



2. Tulp's fetus, quoted by LiceLus, in the appendix to his " De Monstris," 



ed. 1665. The description is accompanied with an excellent engrav- 

 ing and shows a specimen closely resembling Fenn's fetus, but with 

 the double hand components complete and free as far as the wrists. 

 Although Licetus is very unreliable and fantastic, this case is 

 undoubtedly authentic, since it rests upon the authority of Nicolaus 

 Tulp and is in strict accordance with other observed facts.

d. Components united at pelvis, above which they are distinct, each ivith 

 head and pair of arms; the pelvis is often partly doubled, hut with usually 

 a single set of external median parts and with a single pair of legs, each one 

 of ivhich belongs to the upper component on its own side. 



Type: Tocci brothers, Giovanni-Batista and Giacomo; born, province of 

 Turin, Italy, 1887. The components were separate and normal dov/n to the 

 sixth rib, but possessed " a common abdomen, a single anus, two legs, two 

 sacra, two vertebral columns, one penis, but three buttocks, the central one 

 containing a rudimentary anus." A good photograph of these is reproduced 

 in an article by H. L. Osborne, 02. 



Other cases: 



1. Normandy sisters, reported as having been seen in Normandy in 1062.

3. Scottish brothers, b. about 1465; lived 28 years. 



4. Swiss twins, male, b. 1598; lived at least 30 years. " So joined that at
