410 Duplicate Twins and Double Monsters 



furnished with a face, it is altogether probable that any original similarity of 

 features would have been lost. In the records of cases accessible to me in 

 which the parasite possesses sex, it seems always to be the same as that of 

 the autosite, but that in itself is no proof that the components were originally 

 duplicates, although, in accordance with the theories advanced here, it seems 

 probable that the latter is always the case. 



This class of monsters seems harder to arrange in groups than does the 

 preceding and the following attempt is mainly for the purpose of putting the 

 various cases in a convenient form for consideration. 



1. Parasite Attached to the OrTsioE of the Autosite. 



a. Parasite possessed of a head, or head and arms, usually attached to the 

 autosite at or near the epigastrium. 



Type: Lazarus Johannes Baptista Colloredo, b. Genoa, 1617. Exhibited 

 all over Europe. Autosite normal, bearing at the lower sternal region a para- 

 site which consisted of a trunk, one thigh, two arms and a well formed 

 head. The parasite gave signs of independent existence, but the eyes were 

 closed and nothing was ingested by its mouth. The man was examined by 

 Bartholinus. This case seems to be unique in the completeness of the 

 parasite, but several other cases, in some of which the parasite consisted of a 

 head alone, are on record. 



Other cases (less complete than the type) : 



1. Dickinson's case, 1880. Child of five years, with a supernumerary head 



attached by a broad base to the lower lumbar and sacral region. 



2. Havana case. Examined by Montare and Reyes. Girl of seven months 



with an imperfect accessory individual attached between the xiph- 

 oid cartilage and the umbilicus. The accessory head was imper- 

 fect, but had hair; the parasite had in part a separate sensation. 

 Moreau's case. Infant born in Switzerland in 1764. The parasite seems 

 to have resembled that of Colloredo; it was amputated by a liga- 

 ture. 

 &. Parasite consists of the legs and more or less of the lower part of 

 the body, without a head; attachment to autosite as in 1. 



Type: Laloo, Hindoo boy born about 1876; exhibited in dime museums 

 all over the United States. The parasite was dressed in girl's clothes and 

 v/as said to be female, but was in reality a male. The parasite possessed 

 arms, but no head, and had no separate sensation. 

 Other cases: 



1. A-Ke, a Chinaman, exhibited in London early in the nineteenth cen- 



tury, and now largely represented by wax models in continental 

 museums. Case similar to last. 



2. Louise L., " La dame aux quatres jambes," born in 1869. Parasite 



consisted of two atrophied legs on a rudimentary pelvis, attached 

 ventrally to the normal pelvis; two rudimentary mammae at inser- 

 tion of legs. " The woman could localize sensation in the parasite 

 except in the feet." She married and bore two normal daughters. 

 [In some respects, e. g., the rudimentary mammae, this case is strik- 

 ingly similar to Blanche Dumas and to Bechlinger's case (see 

 above), except that here there is no doubling of parts in the 

 autosite.]
