I have met with on this matter, after much
search, yet I collect and present some of them, in the hope that they
will incite to more abundant and more careful observation in the future
than has been made up to this time.

A good many data concerning the behavior of cretin children are to be
found in the very painstaking book, "Neue Untersuchungen ueber den
Kretinismus oder die Entartung des Menschen in ihren verschiedenen
Graden und Formen" ("New Investigations concerning Cretinism, or Human
Deterioration, in its Various Forms and Degrees"), by Maffei and Roesch
(two vols, Erlangen, 1844). But, in order that these data should be of
value, the observed anomalies and defects of the cerebral functions
ought to be capable of being referred to careful morphological
investigations of the cretin brain. As the authors give no results of
_post-mortem_ examinations, I simply refer to their work here.

I once had the opportunity myself of seeing a hemicephalus, living, who
was brought to the clinic of my respected colleague, Prof. B. Schultze,
in Jena. The child was of the male sex, and was born on the 1st of July,
1883, at noon, along with a perfectly normal twin sister. The parents
are of sound condition. I saw the child for the first time on the 3d of
July, at two o'clock. I found all the parts of the body, except the
head, like those of ordinary children born at the right time. The head
had on it a great red lump like a tumor, and came to an end directly
over the eyes, going down abruptly behind; but, even if the tumor were
supposed to be covered with skin, there would by no means be the natural
arched formation of the cranium of a newly-born child. The face, too,
absolutely without forehead, was smaller in comparison than the rest of
the body. I found now, in the case of this child, already two days old,
a remarkably regular breathing, a very cool skin--in the forenoon a
specific warmth of 32 deg. C. had been found--and slight mobility. The eyes
remained closed. When I opened them, without violence, the pupil was
seen to be immobile. It did not react in the least upon the direct light
of the sun on either side. The left eye did not move at all, the right
made rare, convulsive, lateral movements. The conjunctiva was very much
reddened. The child did not react in the least to pricks of a dull
needle tried on all parts of the body, and reacted only very feebly to
pinches; not at all to sound-stimuli, but regularly to stronger,
