There too the proboseis is a totally developed nose, with a septum, 
conchae, and two halves, as it was in the former case. 
The figures 7 and 8 give the reproductions of the brain of this 
monstrum. 
Dorsally the sac (6) appears, adherent to the dura mater (c) and 
opened in d. Ventrally (fig. 8) the fissure in located more distally 
than in the former case, although it is placed frontally from the 
chiasma, and, what is of more importance the burst is not located 
precisely in the midline, but it is deviating and has also ruptured 
the base of the left hemisphere.

cyclopian calve. f. sag. = fissura sagittalis cerebri. 
Letters as in fig. 8 and fig. 5. x= rupture in the basal face of the left hemi- 
sphere. 
For the rest same letters as in fig. 4. 
The frontal brainpole has not remained undivided here. If the 
burst does not keep strictly to the midline and is passing through 
a more distal plan of the brain-base, as may be supposed in this 
case, then there is no reason why the eye-origin on that side should 
not be totally destroyed and a real monorbitary elyeopian being 
will develop, im which the eye is not composed by two eyes, but 
results from the one remaining eye-vesicle. Then too it is not necessary 
that the frontal pole has to remain undivided, for a part of the burst 
passes laterally from the midline. In this case the sagittal fissure becomes
