the experience necessary for distinguishing so simple a phenomenon."
Besides, she was very uncertain in her judgment of distances, and, in
her attempts to seize with the hand new and distant objects, she
frequently acted exactly like an infant.

VII. THE FRANZ CASE.

J. C. A. Franz, of Leipsic, communicates the following to the
"Philosophical Transactions of the Royal Society" (by Sir Benjamin C.
Brodie), (London, 1841; i, pp. 59-69):

"F. J. is the son of a physician. He is endowed with an
excellent understanding, quick power of conception, and
retentive memory. At his birth, both eyes were found to be
turned inward to such an extent that a portion of the cornea was
hidden by the inner canthus, and in both pupils there was a
yellowish-white discoloration. That the strabismus and cataract
of both eyes in this case were congenital is evident from the
testimony both of the parents and of the nurse. The latter held
a light before the eyes of the child when he was a few months
old, of which he took no notice. I ascertained also from her
that the eyeballs did not move hither and thither, but were
always turned inward, and that but rarely either the one or the
other was moved from the internal canthus.

"Toward the end of the second year, as was stated to me, the
operation of keratonyxis was performed on the right eye, upon
which a severe iritis ensued, terminating in atrophy of the
eyeball. Within the next four years two similar operations were
performed on the left eye without success. The color of the
opacity became, however, of a clearer white, and the patient
acquired a certain sensation of light, which he did not seem to
have had before the operation.

"At the end of June, 1840, the patient, being then seventeen
years of age, was brought to me. I found the condition of things
as follows: Both eyes were so much inverted that nearly one half
the cornea was hidden. The left eye he could move voluntarily
outward, but not without exertion; it returned immediately
inward when the influence of the will had ceased. The left
eyeball was of the natural size and elasticity. The patient had
not the slightest perception of light with the right eye; the
stimulus of light had no effect on the pupil. The pupil of the
left eye, which was not round, but drawn angularly downward and
inward, did
