1891.] The Double Monster Rosa-Josepha Blazek, 893 
The rectum is probably single for some distance, as they are 
actuated by a single impulse to defecate; but there are undoubt- 
edly two large intestines. 
According to Breisky, at the age six months there was a 
remarkable asymmetry of the heads of the two children, very 
noticeable if one looked at them from above or behind. 
As regards psychological phenomena, it is now well known | 
that monsters of this kind constitute two distinct personalities, 
and that one has to deal with individuals where brains function 
entirely independently of each other. 
The two girls speak “ Czech,’—that is to say, the language of 
their native land. They can occupy themselves in many ways 
independently of each other. One sleeps while the other is 
awake. The showman relates many amusing stories about the 
different sensations that they experience, but these need to be 
verified. It has been proved, however, that they have not the 
same tastes in the matter of food. One likes beer, the other 
wine; one is fond of salad, the other detests it, etc., etc.; when 
one is thirsty the other does not necessarily experience the same 
sensation. 
The two hearts do not beat in unison, for the radial pulses are 
not synchronous. 
With Millie-Christine, Paul Bert demonstrated that a touch on 
the lower limbs of one individual was perceived by the other; 
whence it was concluded that the caud@e eguine of the spinal 
marrow were united. It does not seem to be so with Rosa- 
Josepha; there is only a very restricted zone in which a sensation 
may be experienced by both at the same time, and this zone cor- 
responds to the middle part of the skin which covers the trans- 
verse mass placed between the pelves,—a place where it might be 
possible to separate the two girls if it should become necessary 
through the death of one of them. It can be inferred from this 
that the union is less intimate than in the case of Millie-Chris- 
tine, and that if the spinal canals communicate at the level of the 
sacrum—which is probable—the -cords are either not united at 
all or but slightly.
